Passenger Terminal Building’s pillar clads in stainless steel

Delhi’s new airport terminal T3 is partof the project for the modernization and upgradationof the Delhi airport awarded to Delhi InternationalAirport Limited (DIAL), a joint venture companyformed by the Bangalore-based GMR Group, AirportsAuthority of India (AAI), Fraport and MalaysianAirport Holdings. T3 Terminal at Delhi’s IndiraGandhi International Airport is the world’s eighthlargest airport terminal.

Terminal 3, a state-of-the-art integrated terminal,occupies 502,000 m² (5.4 million sq ft), with acapacity to handle 34 million passengers annually.The new Terminal 3 is a two-tier building, with thebottom floor being the arrival area, and the top beingthe departure area. This terminal has 168 check-incounters, 30 parking bays for aircrafts, 72immigration counters, 15 X-ray screening areas forless waiting times, duty-free shops and otherfeatures. This terminal has 78 aero bridges, thelargest number for a single terminal anywhere inthe world. It also has a 100-room transit hotel.

The entire terminal had been built in a record timeof just 37 months against the 60-72 months takenin different airports in the world, creating a globalbenchmark.

Some interesting facts about the potential ofstainless steel in the airports sector can be gaugedby the use of stainless steel in T3. For the domesticpiers of T3, the passenger terminal building (PTB)and Airport Connection Building connecting to DelhiMetro and the car parking area, stainless steel type304 in satin finish (surface roughness ra value of0.2 microns) has been used for the followinginstallations:

• 33 Kilometers of handrails and crashguards• 350 Security Bollards• 5,000 Square meters of cladding

The Indian Stainless Steel DevelopmentAssociation (ISSDA) held a hugelysuccessful workshop in Ahmedabad onthe use of stainless steel for buildings.The workshop was held on Saturday 21st

August, 2010. About 350 architects,builders, interior designers, municipal andgovernment officials responsible forenhancing the image and infrastructureof Ahmedabad, stainless steel fabricatorsand members of the stainless steelindustry in and around Ahmedabadattended.

This event was sponsored by RaajratnaMetal Industries Ltd., Fabrica of theSunrise Group, Lancer Laser Tech Ltd.,(all-based in Ahmedabad) and theChennai based M/s Fein Power ToolsIndia Pvt Ltd. All these companies provideproducts and services in stainless steelfor the building and construction sector.

The objective of the seminar was to helpstainless steel fabricators to ensure highquality of architectural products. For thearchitects and designers, it was anextremely useful exercise to know howto identify good quality stainless steelproducts. The presentations were alsomeant to help new-comers to the field ofstainless steel fabrication for this sectorto know how to go about setting up amanufacturing unit, including theequipment and machinery they wouldneed. Availability of consultants for newprojects was indicated to the audience.

Workshop in Ahmedabad -- STAINLESS STEEL FOR BUILDINGS

Highly experienced personnel from thestainless steel industry across Indiasuch as Mr. Ramadas of Salem SteelPlant (SAIL), Mr. Kuldeep Singh of JindalArchitecture at Gurgaon, Mr. KamleshMehta of Stallion Infrastructure,Bangalore, Mr. Rajesh of Fein PowerTools, Chennai, Mr. Nitin Shah of Fabrica,Ahmedabad, Mr. Pravin Goel of JSLStainless Ltd., Delhi, Mr. K RAnanthanarayanan, Consultant, based inBangalore and Mr. Ramesh Gopal ofISSDA made presentations.

The presentations comprehensivelycovered the complete range of activitiesstarting from grades and grade selectioncriteria; architectural images spanning avariety of applications across India; abasic guide to fabrication; surfacefinishing techniques and requirements;the full range of stainless steel productforms available in the market for thissector; indoor plumbing in stainless steelfor pure water and longevity of RCCbuildings; new stainless steel productsthat could be introduced for capturingmore market space and bigger volumesfor stainless steel; and good shop floorpractices for ensuring quality products.

Why did ISSDA do this programme? Thisis because the use of stainless steel forbuildings is mainly in big cities like Delhi,Mumbai, Bangalore, Chennai etc. Notmuch in smaller cities like Ahmedabad.The stainless steel industry wants to

spread the use of stainless steel inbuildings to a large number of cities likeAhmedabad, Chandigarh, Coimbatore,Pune, Nagpur, Aurangabad and hundredsof other tier II and tier III cities throughoutIndia.

Why did ISSDA start with Ahmedabadfor these workshops? First, Gujarat iseconomically most progressive state andAhmedabad is looking forward tooccupying the top slot among cities forits industry and commerce. Second,Ahmedabad is a premiere city forproduction and processing of stainlesssteel. It is therefore natural that thepeople, the fabricators, architects andmunicipal bodies in Ahmedabad wouldpositively respond to our efforts.

Amongst a lot of people who helped,ISSDA is personally thankful to Mr.Ugamraj Hundia of M/s Real Strips Ltd.Ahmedabad, for the wholehearted supporthe gave from day one and who waspresent at the workshop. We are thankfulto ISDO for the co-operation extendedto ISSDA in successfully conducting thisworkshop in Ahmedabad.

Stainless steel production for the first half of 2010: More than 40% increase

Preliminary figures released by the InternationalStainless Steel Forum (ISSF) show that stainlesssteel crude steel production has tremendouslyincreased in the first half of 2010 by 44.3%compared to the same period of 2009. Totalproduction for the first six months of 2010 was15.6 million metric tons (mmt). All major regionsshowed significant higher production volumesin the first half year 2010. Remarkably, Chinareported a lower than average productionincrease.

This never seen before strong magnitude ofstainless steel production growth is reflectingseveral facts:

1. A clear statistical basics effect after thedramatically decreased production in the firsthalf of 2009 due to the world-wide economiccrisis.

2. A much stronger and quicker than anticipatedrecovery of the global economy.

3. A strong re-stocking business – partiallycombined with speculative buying.

4. A re-filling of the mill-internal supply-chain.

In Asia, with China excluded, stainless steelproduction increased by 46% to 4.3 million tons.All stainless steel producing countriessignificantly increased production in the first halfof 2010. Growth rates were between 20 and80%. China increased the stainless steelproduction in the period of review by 35% to5.5mmt.

Western Europe/Africa reported a49% increase in stainless steelproduction during the first sixmonths of 2010. Total productionwas 4.3 million metric tonnes inthis period.

The split by main stainless steelgrades has seen a recoveredmarket share of ferritic stainlesssteels. This clearly reflects thestrong production recovery in the

global automotive industry. The marketshare of austenitic CrNi stainless steelshas slightly decreased compared withthe average of 2009 due to strongerdevelopment of the ferritics. The marketshare of chrome-manganese stainlesssteels has increased somewhat due tothe better market demand in China.

Emergence of Stainless Steel Service Centers

JINDAL STAINLESS STEELWAY LTD.

Jindal Stainless Limited was the firstto envision this big service opportunityin the stainless steel arena. The idea toset up a string of service centres acrossIndia & outside to provide customizedstainless steel, in exact quantities & onexact time, was put on the tablesometime in early 2004 & the moment itwas spelt out, it found widespreadacceptance among all, across theorganization.

Soon after, Jindal Stainless Limitedembarked on its journey, to bringcustomer - centric service solutions. JSLformed a strategic joint venture withSteelway Inox Market Group, in early2004 to form a new organization - JindalStainless Steelway Limited.

Jindal Stainless Steelway Ltd. is thelargest stainless steel service center inIndia which services customers withdifferent grades of stainless steel in tailor-made forms, on just-in-time basis.

The company’s state-of-the-art plants areoperational in Gurgaon (Haryana),Mumbai (Maharashtra) & Chennai (TamilNadu) with another one coming up inBaroda (Gujarat). The company also hasa warehouse facility in Kolkata(W.Bengal) to cater to the North-Eastmarket of India. The strategic location ofall the service centers is essential incatering the scattered stainless steelrequirement of India. Apart from this, thecompany also has a series of satellitemarketing office in all major cities of India.

The Steel Service Centre Industry in Indiais fast developing as an inseparableconnect between the primary steelproducers & its end users.

Till few years ago, around 90 – 95% of Steelin India was distributed to end users byeither the producing mills directly or by thetrading sector comprising of big & small

distributors or stockists. The materials weregenerally supplied in their mother form, asproduced, to be further processed by endusers through local stand-aloneprocessors, to make them usable for endapplications.

But in the last few years, there has been amarked change in steel producers’

approach towards reaching out to its endconsumers. Today, most of them haveforged alliances with internationalcompanies in the steel servicing businessto bring ready-to-use processed steeldirectly to their customers’ doorsteps.

Facilities Installed: The company is equipped with the latest technologically advanced Slitting, Cut-to-Length & SurfacePolishing Lines (No.4, Scotch Brite, Mirror Finish, Anti Fingerprint Finish & Embossing) from the best international equipmentssuppliers Like FIMI & IMEAS of Italy and DAHEWA of Korea.

Matt Finish, Satin Finish – Know from the experts

Stainless steels are a family of steelswith a unique set of properties. Protectedby a passive layer of chromium oxide filmat the surface which is formed by reactionof the chromium in the stainless steeland oxygen in the atmosphere, theyrequire no added surface protectionagainst corrosion.

It is important for surface finishers tounderstand that during the process ofapplying a specific surface finish, THEYSHOULD NOT ENGAGE IN ACTIVITIESthat would destroy the passivity of thesurface. In other words, if you employrough and tough activity with a stainlesssteel surface (as you would tend to dowith carbon steel), you would destroy thecorrosion resistance (read: passivity ofthe surface film) and the job in questionwould inexplicably start showing signsof corrosion in service.

This article attempts to help you achievethe specific surface finish – either Mattor Satin – while retaining the passivity ofthe surface and give your clients decadesof stainless service.

The number of finishing processes forgetting the desired finish can beminimized by selecting, as a startingpoint, the closest mill finish to the desiredresult. To achieve a consistent surfacequality, it is advisable to agree to apolishing specification which mustinclude a surface roughness value Raand inspection. It is in the best interestsof the fabricator and the specifier(architect/designer) that each one keepsa small sample of the agreed finish.

Satin finish is a smooth reflective finish.This finish is obtained by the use of finergrit belts and non-woven brushes whichgives a clean cut finish with a maximumsurface roughness of Ra = 0.4 microns.

Matt finish is less reflective than Satin.This finish is obtained by the use ofbrushes and grinding media with slightly

coarser grains, giving a finish in whichunidirectional texture can be clearlyseen. The Ra value should be specifiedas not greater than 0.7 microns.

To start the finishing process, the roughmill finish on the product must undergometal removal to make the surfaceuniform. For this purpose, differentequipments are available. For instance,variable speed angle grinders and arange of easy-to-change abrasive canbe used with them. It is advisable tostart with coarse removal of 40-60 gritand move down in steps to finer beltsand wheels to say 120 grit before youbegin final process of applying the finishyou need. Please note that it is veryimportant to keep the speed down toavoid excessive heating of surface.Damage caused by excessive heatingcan be difficult to repair and lead toexcessive wear of the abrasive.

Angle Grinder

Set of wheels and belts for grinding(Metal removal)

High speed grinding does not speed upyour productivity. On the contrary, it ispositively more expensive for you bothin terms of time and money.

Applying Final Finishes:

Before applying any of these finalfinishes, please make sure that the lastgrinding operation was by 120 gritgrinding medium. First apply Matt finish,which is the rougher of the two finishes.The Blue and Green wheels in the imageabove are for this purpose. They give youa surface roughness value of less than0.7 microns.

For obtaining a satin finish, use the browncoloured non-woven wheel and obtain thedesired finish. CAUTION: DO NOT SKIPTHE MATT FINISH STAGE. IF YOUDIRECTLY APPLY THE SATIN FINISHWHEEL, YOU WILL LAND UPSPENDING MORE TIME AND MONEY.If you skip the step, the finish quality willnot be uniform or desirable.

If you follow the above guidelines, youwould get an excellent uniform andconsistent finish and the product wouldprovide corrosion free service fordecades.
