Colorcoat HPS200 Ultra® Super durable


The multi-layered structure of ColorcoatHPS200 Ultra® incorporates a uniqueprotective layer and the latest polymertechnology. This means that ColorcoatHPS200 Ultra® is strong, super durable andmaintains its appearance for longer.

Pre-finished steel comprises a number of paintlayers and treatments that are applied to thesteel in an automated and carefully controlledprocess. Each layer has a particular function.The synergistic effect of these various layersensures a material that is robust, versatile andaesthetically pleasing.

Multi-layered functionalityThe functional layers of Colorcoat HPS200Ultra® combine to deliver super durability androbustness. The Galvalloy® metallic coating,pre-treatment and primer provide unrivalled corrosion resistance even at the cut edges.

The unique topcoat formulation (nominal 200microns) utilises leading polymer technology,which provides abrasion, chemical and UVresistance.

Unique Scintilla® embossUnique to Colorcoat HPS200 Ultra® theScintilla® emboss has been developed with adepth of only nominal 50 microns, whichmakes it less likely to trap dirt than deeperleathergrain embosses therefore making thepre-finished steel easier to clean whilst beingmore robust.

Unlike standard leathergrain patterns theemboss is subtle and does not detract fromthe overall appearance of the building,looking smooth and creating a modernbuilding appearance from a distance. TheScintilla® emboss provides a unique guaranteeof authenticity, and an overall thickerprotective topcoat from Tata Steel.

With a world class reputation in steel, TataSteel products and services are widely usedin the construction market. The steelsubstrate for Colorcoat HPS200 Ultra® ismanufactured by Tata Steel.

Strong, versatile and truly recyclable, steel isa compelling choice for the buildingenvelope.

Steel has one of the highest strength-to-weight ratios of any building material –producing strong, lightweight structuresenabling fast build programs that are costeffective without any compromise on quality.

Steel provides:• Functionality, versatility, strength and flexibility.

• Ability to work well with other materials.

• Excellent environmental performance –offering high recyclability and re-usepotential.

• Ability to be pre-fabricated off-site andconstructed quickly and accurately on-site.

• Excellent durability and performance in use.

Designing with steelThe gauge of the steel plays a vital role in thephysical properties and performance of theroof or wall cladding that is manufacturedfrom it. Incorrect specification may, in theworst cases, have safety implications such asroof fragility.

The European standard EN 10143:2006 definesthe tolerances for different grade, width andgauge material for normal and specialtolerance categories. In the case of ColorcoatHPS200 Ultra®, the gauge is measured as thesteel substrate plus the Galvalloy® metalliccoating.

Tata Steel supplies pre-finished steel to normaland special tolerances according to EN 10143:2006 to ensure that the claddingperforms as designed.

Incorrectly specifying gauge or gauge tolerances can affect:1. Structural performance, including in service load capacity and purlin spacingsas well as safety implications duringconstruction and maintenance.

2. Building visual appearance, lighter gaugematerial is more prone to damage duringinstallation, and distortion of the profilearound fasteners due to slight misalignmentof the primary/secondary structure.

Colorcoat HPS200 Ultra® uses our uniqueGalvalloy®metallic coating, a special mix ofZinc and Aluminium that provides unrivalledcorrosion protection, even at cut edges.

How does Galvalloy® work?The metallic coating is essential to theperformance of the pre-finished steel.Traditionally, pre-finished steel products haveused a Zinc metallic coating which is oftenreferred to as Hot-Dipped Galvanised Steel(HDG). This HDG coating does provideimproved corrosion protection, in comparisonwith uncoated steel, but often leaves cutedges vulnerable to increased rates ofcorrosion and will ultimately lead to peelingand/or premature paint delamination.

To address this problem, Colorcoat HPS200Ultra® uses the unique and proven Galvalloy®metallic coating. Galvalloy® is made with aspecial mix of 95% Zinc (Zn) and 5%Aluminium (Al) that conforms to EN10346:2009.

The carefully developed proportions of Zincand Aluminium (Zn-Al) in Galvalloy® offer acombination of increased barrier and sacrificialprotection when compared with conventionalHDG coatings.

The sacrificial protection results frompreferential corrosion of the Zinc over thesteel, and the barrier protection results fromthe presence of a stable Aluminium oxidelayer on the surface of the Galvalloy® coating,both of which inhibit and slow the rate ofanodic undercutting compared toconventional HDG metallic coatings.

The Aluminium in the metallic coating ofGalvalloy® and the manufacturing parametersare optimised to give a very fine two-phasemicrostructure compared with the uniformmicrostructure of HDG.

A typical microstructure of Galvalloy® is shownin figure 7 where the primary Zinc dendritesmake up approximately 20% of the bulkmicrostructure and the Zinc/Aluminiumeutectic the remaining 80%.

Primary Zinc Zn-Al eutecticdendrites


For a product using conventional HDG, thecorrosive attack will dissolve all of the metalliccoating at the same rate – leading to obviouspeeling of the paint system as the paint hasnothing to adhere to.

For the same time period, the optimisedGalvalloy® microstructure has a majoradvantage in that the corrosion will occur intwo stages.

Initially, the Zinc phase will be corrodedpreferentially to the Zinc/Aluminium eutectic.As the paint adheres to the eutectic structure,no edge peel is observed.

Over time, the eutectic structure will corrode –but at a greatly reduced rate when comparedwith HDG coatings and thus results in longerdurability.

In addition to exhaustive artificial testing,Galvalloy® has been subjected to prolongedand independent natural weather testingsince its introduction in 1998. Its proven,superior performance means that Galvalloy®lasts for a longer time period than HDG andremains the preferred metallic coating for ourlatest generation of super durable pre-finishedsteel, Colorcoat HPS200 Ultra®.

The micro cross-section of Galvalloy®illustrates the before, figure 8, and after, figure9, corrosion process. It clearly shows the Zincdendrites corroding at a faster rate than theZinc and Aluminium eutectic composition. Theprotective Zinc and Aluminium phase is leftbehind and remains adhered to the organiccoating providing improved corrosionprotection.

Figures 8 and 9 illustrate how, as the lighter colouredZinc dendrites ultimately corrode, the uniquemicrostructure of the Galvalloy® layer ensures thatthe surface coating remains adhered to the eutecticsurface.

The super durability of Colorcoat HPS200Ultra® derives from its Galvalloy® metalliccoating, high performance primer and thick,durable barrier topcoat which providesexcellent scratch and abrasion resistance.Testing of products is carried out in UKASaccredited laboratories to EuropeanStandards.

Testing has shown that Colorcoat HPS200Ultra® benefits from high levels of scratch andabrasion resistance, the advantages are:

• Less susceptible to damage during storage,handling and construction.

• Longer life of the completed buildingenvelope due to superior resistance towind-blown material and site damage.

• Robustness of the top coat reducing therequirement for filming before profiling.

Scratch testsThe scratch test method is a technique thatapplies critical loads to a sample to test atwhat point failure appears – testing thecohesive and/or adhesive properties of pre-finished steel. Colorcoat HPS200 Ultra® hasbeen tested alongside a typical PVDF and apolyester product. During the test, samples ofColorcoat HPS200 Ultra® were scratched with aneedle which was drawn at a constant speedunder a progressive load. The test wasconcluded when sufficient weight was addedto cut through the Colorcoat HPS200 Ultra®sample revealing the metallic coating. Themore weight recorded the greater theresistance of the topcoat.

The unique topcoat formula meant thatconsiderably more weight was required toexpose the metallic coating on ColorcoatHPS200 Ultra® when compared to othercoating types as shown in figure 10.

Falling sand testAbrasion resistance is commonly tested by the‘falling sand’ test to ASTM D968:2001. This testmeasures the stream of falling sand requiredto erode a paint system - to determine thetopcoat’s resistance.

Colorcoat HPS200 Ultra® was tested against atypical PVDF product. Results showed thatmore than twice as much sand was requiredto expose the metallic coating of ColorcoatHPS200 Ultra® compared to alternativeproducts tested.

Natural weather testing is an essential partof testing the corrosion resistance of a pre-finished steel product. Colorcoat HPS200Ultra® has undergone a comprehensiveprogram of testing in key weatheringclimates around the world – achieving thehighest classification possible.

Exposure sites for Colorcoat HPS200 Ultra®were chosen to provide the full spectrum ofweathering zones - from equatorial andtropical climates to urban, rural, industrial andcoastal locations.

Samples of Colorcoat HPS200 Ultra® havebeen tested and remain exposed atweathering sites in USA (Florida, Arizona,Ohio), Australia, China, India, Dubai, Sweden(Bohus Malmon), France (Brest) and sitesacross the UK. This has enabled us to build upa comprehensive assessment of the corrosionresistance of Colorcoat HPS200 Ultra® in awide-range of extreme climates.

Figure 12. RC5 Certificate for Colorcoat HPS200 Ultra®

Highest corrosion classificationColorcoat HPS200 Ultra® has undergoneextensive corrosion testing in accordance withthe European Standard EN 10169:2010‘Continuously organic coated (coil coated) steelflat products’. Samples of Colorcoat HPS200Ultra® were exposed to the extreme coastalenvironment of Brest on the west coast ofFrance to assess corrosion resistance.

The European Standard requires the samplesto have more than two years exposure at thesite. During this time they must be able toresist blistering, coating damage and edgepeel (containing any edge peel to less than2mm) in order to achieve the highestcorrosion resistance classification of RC5.

After independent assessment, The FrenchCorrosion Institute concluded that ColorcoatHPS200 Ultra® achieves RC5 corrosion rating inaccordance with EN 10169:2010. An example ofone of the Colorcoat HPS200 Ultra® test panelsis shown in figure 13. This shows no edge peeland no surface damage or blisters after morethan two years exposure at Brest, France.

Colorcoat HPS200 Ultra® utilises the optimisedGalvalloy® metallic coating, which is anessential element of it’s super durableproperties. We have gone beyond the twoyear testing period required for Europeanstandards to examine products dating back tothe 1990’s when the unique Galvalloy®metallic coating was first introduced to themarket, to assess its superior performancequalities over Hot-Dipped Galvanised Steelmetallic coating.

In 1998 Galvalloy® metallic coating was usedwith an earlier generation of the product –Colorcoat HPS200®. Samples of this productwere exposed at Bohus Malmon (figure 15)and Rye (figures 16 and 17) to evaluate theperformance of the Galvalloy® metallic coatingand corrosion resistance primer.

Bohus Malmon is a C4/C5 classified site (high /very high corrosivity) as per EN 10169:2010 on

the West coast of Sweden, Rye is situated inthe UK within 50 metres of the sea in thesouth of England and would typically be a C3site (moderate corrosivity).

After more than 13 years of exposure at Ryeand 10 years at Bohus Malmon there isvirtually no edge delamination (measured asless than 2mm), blistering or any other surfacedegradation of Colorcoat HPS200®.

This long-term exposure demonstrates theexcellent performance of the Galvalloy®metallic coating combined with the optimisedcorrosion-resistant primer.

The performance of the corrosion resistanceprimer is further demonstrated by theevaluation of Colorcoat HP200® that wasproduced in 1993, that has been exposed formore than 18 years at Rye.

Natural weathering testing of corrosionresistance can be greatly acceleratedthrough the use of specially designedweathering chambers. The super durableproperties of Colorcoat HPS200 Ultra® havebeen proven through extensive andaggressive accelerated corrosion tests.

Accelerated corrosion testsSamples of a representative selection of theColorcoat HPS200 Ultra® colour range wereput through a series of rigorous tests designedto predict the corrosion resistance of theproduct in different environments – coastal(salt spray), humidity, prohesion (cyclic wetand dry), water soak and Kesternich (acid rain).The tests are symbolic and often are far moreaggressive than would be seen in real worldsituations.

Samples of Colorcoat HPS200 Ultra® - with oneedge exposed and a cross scribed into thecoating to simulate site damage, were placedin UKAS accredited test chambers for therequired test duration. The results of theseaccelerated corrosion tests are given in table 3.

Representative photographs of ColorcoatHPS200 Ultra® in Goosewing Grey after 1000hours testing in this suite of accelerated testsare shown in figures 19-22.

Both saltspray (continuous fog of sodiumchloride) and prohesion (cyclic phases ofsodium and ammonium chloride fog followedby a drying cycle) are extremely aggressiveaccelerated corrosion tests. Despite this, theUKAS tests showed that the extent of paintdelamination at both the cut edge and scribeis minimal.

The Kesternich test (moist/humid sulphurdioxide test) is designed to simulate thedamaging effects of harsh environments,particularly sulphur dioxide contaminants andacid rain.

Colorcoat HPS200 Ultra® showed minimal (lessthan 3mm) edge and scribe delaminationfollowing repeated cycles of testing.

Following 1,000 hours of humidity and watersoak tests, no blistering or significant paintdelamination was observed on the ColorcoatHPS200 Ultra® panels. This demonstrates

excellent paint adhesion between theGalvalloy® metallic coating and the organiclayers of Colorcoat HPS200 Ultra®. In figures21, 22 and table 4 the topcoat has beenremoved to clearly show absolutely no creepat the scribe, or cut edge.

Even after5000 hours testing, the test results clearlyshow no evidence of blistering, surfacedegradation or creep at both the edge orscribe for the Colorcoat HPS200 Ultra® sample.Both the generic PVDF and 25 micronpolyester pre-finished steels exhibit extensiveblistering in the samples with all 4 sides taped.The exposed edge and scribe also exhibitsignificant creep and blistering whencompared to Colorcoat HPS200 Ultra®.



In the internal environment of a building,corrosion factors can be increased by thecreation of a microclimate. Colorcoat HPS200Ultra® has been tested and proven toprovide the highest level of corrosionprotection for internal environments.

Increased corrosion factorsIn normal external atmospheres the rate ofcorrosion is accelerated by the following factors:an increase in relative humidity; frequency ofcondensation (time of wetness); the amount ofpollution and rising temperatures.

In the internal environment (ambience) of abuilding these corrosion factors can be greatlyenhanced by the creation of an internalmicroclimate as a result of activities carriedout inside the building such as manufacturing,waste processing or swimming pools.

A building’s internal environment can beclassified according to its corrosivity. Theprincipal factors that determine the corrosivityof internal environments are the risk ofcondensation (time of wetness) and theaggressiveness of any chemicals present andcleaning operation. Table 5 provides guidanceon different levels of aggressiveness for eachof these factors.

These factors are considered in theEN10169:2010 classification of internalambience types. The five categories rangefrom ‘non-aggressive’ to ‘very aggressive’. Veryaggressive environments include those withhigh chemical aggressivity levels wherecleaning agents with a pH of 5–9 are useddaily and environments with a high andpermanent risk of condensation.

Internal certificationCoil coating standard EN10169:2010 classifiesthe suitability of organic coatings for use ininterior environments. Excellent test resultsmean that Colorcoat HPS200 Ultra® is classifiedas a CPI5 product. This is the highest classifiedlevel of corrosion protection for interiors andmeans that Colorcoat HPS200 Ultra® is suitableto be used in the most demanding internalenvironments such as swimming pools andsewage treatment plants.

The thick topcoat of Colorcoat HPS200 Ultra®provides an extra barrier between theatmosphere and the steel substrate –considerably delaying the onset of corrosion.Permeability tests prove the superiorperformance of the product.

Atmospheric corrosion is an electrochemicalprocess that takes place in a thin film of wateron the steel surface. Both water and oxygenare required to instigate corrosion.

Pre-finished steels, apart from the aestheticbenefits, provide a barrier that blocks thepassage of water and oxygen reaching themetal surface and hence slows the corrosionrisk. Top coats on pre-finished steel aregenerally semi permeable to water andoxygen transmission and the greater theirability to restrict transmission - the moredurable the pre-finished steel overall.

Colorcoat HPS200 Ultra® has been developedto ensure an effective and long-lasting barrierbetween the internal atmosphere and thesteel substrate – deferring the onset ofcorrosion. The robust topcoat plays a vital rolealongside the Galvalloy® metallic coating andprimer in preventing corrosion.

Recent test results show low levels of waterand oxygen permeability of Colorcoat HPS200Ultra® when compared to other generic paintsystems.

Water permeabilitySamples of Colorcoat HPS200 Ultra® weresubjected to water vapour transmission/vapour permeance tests undertaken by thePaint Research Agency. The tests were carriedout in accordance with ASTM D1653 using testmethod B – wet cup method, condition A.Within this test method, samples of thefreepaint film are sealed over a vesselcontaining water which are placed in a testchamber with a controlled atmosphere.Regular weighings of the vessel are made todetermine the rate of water movementthrough the paint film. The purpose of thistest was to obtain values for water vapourtransfer through the different coating typesand provide a relative rating of the coatingswhen they are tested under the same closelycontrolled conditions.

The results presented in the table belowclearly show that the thicker barrier topcoat ofColorcoat HPS200 Ultra® was considerably lesspermeable to water vapour than other genericpre-finished steel.

Oxygen permeabilityAll paints and polymers are oxygen-permeablebut tests conducted by Smithers Rapraconfirmed that the thick barrier topcoat ofColorcoat HPS200 Ultra® was significantly lesspermeable to oxygen than other generic pre-finished steel products. All paint filmswere tested using the constant volumemethod as detailed in BS ISO 2782:2006. Thetemperature of the test was maintained to23°C and conducted using oxygen at 1 Bar.

Due to its tough, less permeable topcoatColorcoat HPS200 Ultra® also providesexcellent chemical resistance. Along with ahigh level of resistance to humidity, thismakes the product the ideal choice foraggressive internal environments.

When Colorcoat HPS200 Ultra® is used forinteriors including double sided applications,its super durable topcoat provides excellentchemical resistance – when in direct contactwith the chemical and also when exposed tochemical vapour.

Chemicals and pollutants accelerate corrosionby attacking the chemical bonds that make upthe topcoat polymers. In aggressive internalenvironments, where chemicals are present,this can result in discolouring and degradationof the topcoat. The information providedbelow relates to the effects of chemicals onColorcoat HPS200 Ultra®. Any exposed steelsuch as cut edges must be protected with asuitable lacquer or protective coating system.

Independent testing under strict laboratoryconditions has proven the impressivechemical resistance levels of Colorcoat HPS200Ultra® in the vast majority of tests.

Chemical resistance performance is rated on ared, amber, green scale. Green is acceptable,amber requires further advice from Tata Steeland red means it is unsuitable for use with thischemical.

Independent tests show that:• Dilute acids at room temperature do not

normally attack the top coat of ColorcoatHPS200 Ultra®; only concentrated acidsattack the topcoat – normally after aprolonged period of exposure.

• Aqueous solutions of alkalis such asammonia and caustic soda do not attackColorcoat HPS200 Ultra® except in highconcentrations at elevated temperatures.

A pre-finished steel must resist thedamaging affects of the suns emissionsincluding Ultra-Violet and Infra-Redradiation. Exposure to solar radiation cancause a deterioration of colour and glossretention, both of which are precursors ofpaint cracking and delamination. ColorcoatHPS200 Ultra® is classed as RUV4 - thehighest classification of UV resistance. Thisproven and superior UV resistance meansoutstanding colour and gloss retention,resulting in a superior product that lastslonger.

Sun and pre-finished steelThe sun emits a spectrum of light energy(figure 23) including invisible ultraviolet (UV),visible light and infrared radiation (IR). Theshorter wavelengths of UV radiation - whichinclude UVB and UVA radiation - are the mostdestructive on polymer materials. The UV lightis absorbed directly by the polymer andpigment at the molecular level, ultimatelyleading to the breaking of chemical bonds.This results in loss of colour and gloss,chalking, brittleness and, eventually, loss oftopcoat adhesion. The length of time that thistakes depends on the durability of the pre-finished steel, as depicted in figure 24.

Figure 24. Light degradation over time

Colorcoat HPS200 Ultra® has been developedto offer outstanding UV resistance throughincorporation of the latest polymertechnology in its durable topcoat. This 200micron topcoat contains specially developedheat and UV stabilisisers which mitigate anydegradation caused by the absorption of UVradiation together with advanced plastisisersthat increase the durability of ColorcoatHPS200 Ultra® compared to alternative pre-finished steel products.

The IR radiation is also absorbed at themolecular level (solar absorption) whichresults in the topcoat heating up. Such solarabsorption can cause thermal degradation ofthe polymer chemical bonds. The extent ofthis IR absorption is dependant on acombination of the colour pigments used and

other constituents within the paint that canreflect certain proportions of this radiation.The incorporation of an advanced package ofheat stabilizers in combination with the latestpigment technology within the topcoat ofColorcoat HPS200 Ultra® reduce the affect ofIR radiation damage resulting in a productthat maintains it colour and gloss for longer.

The UV resistance of Colorcoat HPS200 Ultra®has been extensively tested andindependently verified with a suite of naturaland accelerated tests that range in theirseverity. Samples have been exposed andremain exposed at weathering sites that coverthe full spectrum of weathering zones such asFlorida, Arizona, Prescott Arizona, Dubai,China, India, Australia and sites within the UK.

RUV4 requirements

UVA testingTo meet the requirements of RUV4, samples areexposed to artificial UVA radiation for a total of2,000 hours as well as two years at anaccredited weathering site with a cumulativeUV radiation in excess of 4,500 MJ/m2 per year.Colorcoat HPS200 Ultra® has been subjectedto both of these testing conditions.

EN 10169:2010 stipulates that, for RUV4classification:

• The percentage gloss retention (% GR) mustbe greater than 80% after each test and theextent of colour change (ΔE) must be lessthan 2ΔE for artificial UV testing and lessthan 3ΔE following natural weatheringexposure.

In both tests, Colorcoat HPS200 Ultra® easilymeets these requirements in terms of thestipulated colour and gloss retention whichprovides clients with even greater reassurancethat their buildings will retain their true colourfor longer.

The superior UV resistance of ColorcoatHPS200 Ultra® has been independentlyverified by ATLAS following exposure at theFlorida weathering facilities. Figure 25 is theRUV4 certificate for Colorcoat HPS200 Ultra®.

Extended testingIn addition to the standard tests for RUV4classification, samples of Colorcoat HPS200Ultra® have completed more than 6,000 hoursof exposure to artificial UVA radiation – threetimes the required length of testing. Even afterthis extended testing period, ColorcoatHPS200 Ultra® still met the requirements ofRUV4. The tests showed that Signature colourshad a ΔE of less than 1.0 and the Classic andMatt colours had a ΔE of less than 1.5.

Extended testing: All colours had a percentagegloss retention greater than 80% even afterthis accelerated test. The Matt colours had agloss retention greater than 100% and as suchare not represented in the graph.

Continuing with testing the product beyondindustry standards. Colorcoat HPS200 Ultra®has been subjected to extended UV testingand long term natural weathering.

UVB testingDue to the short wavelengths of radiation inUVB testing it is more damaging to polymersthat UVA artificial testing. Samples ofColorcoat HPS200 Ultra® have also beenexposed to artificial UVB radiations for 6000total hours. Even after this extended exposurein this harsh testing environment, ColorcoatHPS200 Ultra® Signature colours have a ΔE ofless than 1.5 and a percentage gloss retentiongreater than 50 per cent, with nodelamination between the topcoat andsubstrate. When Colorcoat HPS200 Ultra® iscompared to standard leathergrain pre-finished steel exposed for 2000 total hoursin the UVB test, performance in terms ofcolour and gloss retention are superior.

Xenon testingIn addition to UVA and UVB artificial testing,Colorcoat HPS200 Ultra® has undergoneXenon testing – a whole-spectrum testdesigned to simulate natural sunlight. Xenontesting closely follows the full sun spectrumfrom typically 300 to 3000nm wavelength andtherefore covers all UV, visible and IR radiation.

The average colour and % GR results forColorcoat HPS200 Ultra® Signature and Classiccolours tested after 2000 light hours (2400total hours) is a ΔE of 1.7 and a % GR > 80 percent with no delamination.

Natural weatheringIn addition to the accelerated weatheringprogramme, Colorcoat HPS200 Ultra® hasbeen exposed to full scale testing at ournatural weathering facilities, which confirmsthe proven performance and super durableproperties of the product.

By the end of 2011, initial production samplesof Colorcoat HPS200 Ultra® had beensubjected to more than three years ofexposure at the ATLAS weathering facilities inFlorida.

The UV resistance demonstrated by ColorcoatHPS200 Ultra® under these natural weatheringconditions provides further proof of itsdurability and excellent colour and glossretention. After three years exposure in Floridathe colour change was approximately 1.0ΔEwith a % GR approximately 80 per cent.

Figure 31. Colorcoat HPS200® after 8 yearsexposure in Florida

A year’s exposure to sunlight in Florida canequate to four to seven years of exposure inNorthern Europe. Based on the test results todate, Colorcoat HPS200 Ultra® has had UVexposure equivalent to up to 21 yearsexposure in Northern Europe with excellentgloss and colour retention.

A whole suite of natural weathering andaccelerated tests are used to assess the UVperformance of Colorcoat HPS200 Ultra®. Asindicated in figure 30 this suite of tests rangein both exposure time and aggressivity of thetest environment. The collated test dataprovides an understanding and reassuranceon the performance of Colorcoat HPS200Ultra® in different world wide climates. Thissuper durable UV performance quality hasenabled Colorcoat HPS200 Ultra® to be usedon prestigious projects throughout the worldwith Tata Steel backed warranties issued on acase by case basis.

Understanding reflectivity and emissivity ofpre-finished steel is important, to evaluatetheir affect on thermal loading and theurban heat island effect.

The sun’s infrared (IR) light is absorbed bymaterials, causing an increase in surfacetemperature that can be greater than thesurrounding air temperature. The ability of apre-finished steel system to reflect IR light canhave a significant effect on the building’stemperature, decreasing the need for highenergy consumption in air conditioning, andthe amount of thermal expansion of thecladding profile. Colour has a significant effecton the Total Solar Absorption (TSA) of IRradiation with a black roof reaching a fargreater surface temperature than a white roofunder the same climatic conditions.

Figure 32. Solar reflectivity

All colours in the Colorcoat HPS200 Ultra®range have been tested to determine theirreflectivity performance. The heat absorptionand emittance values for each colour havealso been measured, along with the maximumsurface temperature for the various coloursunder standard conditions. The total solarreflectance (TSR) was measured according toASTM E903-96 and emissivity according toASTM C1371-04a.

Several Signature colours have exceptionalreflective properties (table 10) in that virtuallyall of the sun’s radiation is reflected - resultingin a coating that does not heat up comparedto other pre-finished coatings. This reductionin thermal load minimises heat gain indoorsand in turn energy consumption required tocool the building, and reduces the urban heatisland affect by lowering outdoortemperatures. The total solar reflectance (TSR)and emmitance values quoted in the tablebelow are beneficial when undertaking wholebuilding assessments such as LEED which giveadditional credits for solar reflective products.

Confidex® is the product performanceguarantee for the weatherside of ColorcoatHPS200 Ultra®, when used in an externalconventional building envelope applicationnamely roof and wall cladding using singleskin, built-up or composite panel constructionin industrial and commercial buildings.

Confidex® offers the longest and mostcomprehensive guarantee for pre-finishedsteel available in Europe with ColorcoatHPS200 Ultra® being guaranteed for up to 40years. Dramatic and unrivalled improvementsin colour stability and gloss retention aretranslated into a durable product with greatlongevity. We are so confident in our productthat we cover the cut edges for the entirety ofthe guarantee.

The Confidex® Guarantee is project specificand upon registration online - provides acontractual relationship between Tata Steeland the building owner meaning that in thecase of a claim the contact with Tata Steel isdirect rather than having to go through thesupply chain, saving time and money.

With no mandatory inspections ormaintenance, we remove the need to go on tothe roof to maintain the validity of theguarantee – Confidex® is the only pre-finishedsteel guarantee on the market that offers this.

What’s more, the Confidex® Guarantee istransferable, so should the building ownerchange it is simply a case of filling in the formon the back of the guarantee certificate andposting back to Tata Steel.

Who registers?Usually the building owner, claddingcontractor or the cladding systemmanufacturer, but anyone in the supply chaincan apply online at: www.colorcoat-online.com/registration

If you want to check your building has beenregistered, contact the Colorcoat Connection®helpline on +44 (0)1244 892434.

Other warrantiesWhilst Confidex® has always been restricted tothe weathering performance of the externalcladding, we have recognised the growingemergence of demanding internalenvironment projects, such as energy fromwaste plants, and may offer a non-Confidex®warranty on a case by case basis for ColorcoatHPS200 Ultra® used internally.

Application specific warranties are alsoavailable for non-standard claddingapplications; i.e residential roofs, retro fittingPV modules, flashings and sectional rollershutter doors. Please contact the ColorcoatConnection® helpline forguarantees associated with such applications.

Colorcoat HPS200 Ultra® Guarantees

The British Board of Agrément Certificate

Don’t just take our word for it, ColorcoatHPS200 Ultra® has been assessed by theBritish Board of Agrément (BBA) which is theUK’s major authority offering approval ofconstruction products, systems andinstallers.

The BBA awards Agrément Certificates to aproduct only after it has successfully passed

a comprehensive assessment involvinglaboratory testing, on-site evaluations andinspections of production.

Colorcoat HPS200 Ultra® has been awardedAgrément Certificate 91/2717 by the BBA forindustrial, commercial, retail and leisure useand for residential and non-residentialdwellings.

The BBA states: “Colorcoat HPS200 Ultra®coating and metal treatment will protect thesteel substrate against corrosion for a period inexcess of 40 years in normal industrial, urban, suburban and rural environments.”


Sustainability in terms of material usage,construction, occupation and end of life hasbecome an important consideration in thedesign and specification of buildings. Ourcommitment to sustainable practice isexemplified in the development,manufacture and support of ColorcoatHPS200 Ultra®.

Increasing focus on sustainability is beingdriven by factors such as legislation, consumerpressure and a desire to provide a betterquality of life for people withoutcompromising the future. We have an ongoingcommitment to reduce CO2 emissionsassociated with pre-finished steel manufactureand we work with leading experts to ensurethe both Colorcoat® products and the roof andwall cladding systems that it is part of,contribute to sustainable building envelopesolutions - now and in the future.

Steel manufactureTata Steel are continuing to work hard tosubstantially reduce the embodied CO2 in itssteel products. We have a climate changestrategy with a clear objective to reduce CO2emissions from steelmaking by 20% by 2020.This is being delivered through a mix of majorand smaller investment projects, goodhousekeeping and burden optimisation insteelmaking.

We are also working on a long-term ‘Ultra LowCarbon Dioxide Steel’ project with otherEuropean steelmakers to identify a step changereduction in CO2 emissions in excess of 50%.

The steel used in Colorcoat HPS200 Ultra® ismade by Tata Steel at Port Talbot in SouthWales where £60 million has been invested tocapture the ‘offgas’ generated in steelmakingfor use as an energy source. As well assignificantly reducing electricity and naturalgas requirements, the scheme reduces theplant’s CO2 emissions by 3% per year.

Colorcoat HPS200 Ultra®manufactureColorcoat HPS200 Ultra® is manufactured atthe Tata Steel site at Shotton in North Wales.At Shotton we have strategies to deliversignificant reduction in Shotton site CO2emissions have included: a move from road to100% rail for all feedstock coming from TataSteel in South Wales; a focus on process andoperational energy reduction initiatives suchas installation of variable speed drives, energy-efficient lighting and participation inan ‘energy from waste’ scheme.

Colorcoat HPS200 Ultra® uses steel made byTata Steel from a combination of recycled steelscrap and molten iron. At Shotton we settargets to ensure the efficient use of materialssuch as Zinc and paint to minimise waste.More than 95% of our Zinc pot waste isreclaimed and recycled. Solvents used forwashdowns are filtered, distilled and returnedto us as a 50% recycled blend.

Sustainable design and useA key part of sustainable design is specifyingproducts that offer long-term performanceand minimised emissions during the life timeof the building. The super durable propertiesof Colorcoat HPS200 Ultra® are backed by theConfidex® Guarantee. This provides cover forup 40 years with no requirement forinspection or maintenance to validate it,avoiding additional emissions generated byin-service maintenance, repair or replacement.

We have worked closely with the leadingarchitectural school at Oxford BrookesUniversity to study the operational impacts ofa building and identify the contribution thatpre-finished steel cladding can make to itsefficient running. This work has found that theoperational CO2 of a building can far outweighthe embodied CO2 associated with thebuilding fabric and construction. On very largebuildings it can account for as much as 80% oftotal CO2 of the building life cycle.

Optimising the building envelope efficiencythrough insulation, high air-tightness levelsand the minimization of linear thermalbridging can reduce the operational impacts.We have provided best practice advice andguidance on detailing in our Colorcoat®technical papers so that cladding systemsmanufactured using Colorcoat HPS200 Ultra®can reduce the associated heat losses from thebuilding envelope.

All Tata Steel supply chain partner roof andwall cladding systems in the UK have detailsdesigned and modelled to improve thethermal performance of the building.For more information visit www.colorcoat-online.com/technical

Investing in sustainable buildingenvelopesTata Steel, together with the Low CarbonResearch Institute and Welsh AssemblyGovernment, has invested £6 million in thecreation of a ‘Sustainable Building EnvelopeCentre’ at the Tata Steel site in Shotton, NorthWales. The aim is to create a constructionprocess which will enable the façade ofbuildings – both roof and walls – to betransformed from a passive energyconservation role to an active energygeneration, storage and management function.

Tata Steel Europe is also the lead industrialpartner in an academic and industrialconsortium led by Swansea University that isworking on a multi-million pound project todevelop hi-tech, sustainable, coated productsfor building envelopes. The project, namedSPECIFIC (the Sustainable Product EngineeringCentre for Innovative Functional IndustrialCoatings) aims to develop a portfolio ofproducts that will turn buildings into powerstations to generate over one third of the UK’srequirement for renewable energy by 2020.

Colorcoat HPS200 Ultra® Sustainability


System environmental assessmentIn the UK all roof and wall systems using pre-finished steel achieve a Green Guide A+ rating.Manufacture and processing of ColorcoatHPS200 Ultra® into building envelope products,through our approved supply chain, canmaximise credits assessed through BREEAM.

Colorcoat HPS200 Ultra® is exclusively fromTata Steel and, as such, is fully traceable. Ourmanufacturing site has an environmentalmanagement system which has been certifiedto ISO 14001.

End of lifeWhen the building envelope comes to the endof its life, there are options to either extend it'slife further or ensure that it is disposed ofsafely and with minimum impact botheconomically and environmentally. By usingappropriate maintenance and remedial actionsuch as over-painting, Colorcoat HPS200 Ultra®can last almost indefinitely. If corrective actionis not an option there is a well established andvery efficient infrastructure which ensures thatall steel collected at end of life goes back intosteel manufacture. This means that theinvestment in steel-making is never wasted,making steel the most sustainableconstruction material.

Colorcoat HPS200 Ultra® is truly recyclablewithout any loss of quality, time after time.This makes Colorcoat HPS200 Ultra® a cradleto cradle product in that, at the end of its life,it can be reused or recycled rather than bedisposed of as waste.

Life cycle assessmentWe take a holistic approach to understandingand minimising the environmental impactsover the whole life of the building. Thereforewe constantly strive to ensure that themanufacturing processes and materials usedto manufacture Colorcoat HPS200 Ultra® are

the most sustainable available. Moreover it'senhanced robustness and durability meansthat it significantly outperforms other pre-finished steel in terms of environmentalimpacts over the full life cycle.

To demonstrate environmental impacts and toallow you to make detailed comparisons andinformed decisions when purchasingconstruction products, Tata Steel has carriedout comprehensive life cycle assessments on awide range of cladding systems using ColorcoatHPS200 Ultra®.
