Two pillar systems

Aluminium profi le rail system ALFREI_AL

This system combines the various advantages of ALFREI with a reduced assembly eff ort and a minimum number of required system parts. The piles and struts are aluminium profi les as are the carriage and assembly profi le rails. These are designed and manufactured to fi t with your desired module angle.

ALFREI_AL_BF(aluminium profi le rail system on concrete foundation)

This system with high quality beams, supports, carrier and mounting rails can also be design-ed for a concrete foundation. The angles are delivered pre-assem-bled and therefore can be easily fi xed to the concrete strip founda-tions or existing concrete areas. This reduces the assembly eff ort required. Delivery includes fi xing anchor and dowel technology.

ALFREI_AL_DF(aluminium profi le system on screw foundation)

ALFREI_AL_DF has been optimised for the fi xing to screw foundations with pre-assembled angles which reduces the work eff ort required. Corrosion resistant stainless steel bases are used to connect the steel tubing frame to the screw foundation.

Aluminium angle system ALFREI_WK

This system uses an assembly principle similar to the fl at roof system ALFLACH. It consists of aluminium angles and generally is distinguished from ALFLACH by not having a continuous base rail. The foundation is either con-crete strips or existing concrete fl ooring. Other foundation options are also available. The angle of the modules is adjusted to the site requirements.

ALFREI_RAMM_2P(Pile foundation with two pillars)

If you have a small surface area available, option ALFREI_RAMM_2P with two pillars off ers maximum yield. Even with two pile founda-tions, this two pillar system is quickly assembled. Cross beams or diagonal struts are not required as the pillars are fi xed to the ground. The large width between supports distinguishes this system. The angles are defi ned through positioning of the piles but can be corrected by changing the depth of the pile driving. The bracket that has been developed as connection between the pile and frame, is independent from the required angle and pre-assembled for an uncomplicated assembly.

Steel tubing system ALFREI_ST

This system is suitable for high loads due to its steel tubing construction. Cross beams and diagonal struts make the structure rigid against side forces, especially those caused by wind. This pre-vents the need for large diameters piles and therefore saves material. In addition the system is height adjustable.

ALFREI_ST_BF(steel tubing system on concrete foundation)

The steel tubing system for concrete is a compelling choice as it off ers optimum material use. The fasteners as well as concrete strips and existing concrete fl ooring fulfi l the static requirements. Delivery includes fi xing anchor and dowel technology. We can also off er design of the concrete elements if required.

ALFREI_ST_DF(steel tubing system on screw foundation)

ALFREI_ST_DF can cope with the worst soil conditions. This option of the system is fi xed with established screw foundations. Especially for sandy or gravelly grounds which don’t off er pile foundations enough opportunity to distribute the weight, are screw foundations the best solution. As the foundations are screwed, it enables the system to withstand the largest possible extraction forces. Additionally, the ability to adjust the height of the pillars allows for assembly on uneven grounds.

All our components used for fl at roofs can also be used for the assembly of open ground mounted systems.

We recommend:

· Rail connectors

· Rail extension connectors

· End caps

· Slip preventers

· Theft prevention

· Laminate click clamps

· And more

The ALFREI mounting system has been designed specifi cally as a ground mounted PV-system for open areas. It holds most commer-cial modules in one or more rows, horizontally or vertically. The use of high quality materials allows for maximum stability and longevity of the frame.

The angle of the modules can be adjusted to optimise the use of the sun’s energy and the local conditions.

The system is available in various options to fi t the local ground conditions. The mounting frame consists of aluminium profi le rails in all options and comes with fasteners such as cross connec-tors, rail connectors and module clamps which can be fi xed quickly. The supporting system technology depends on the local conditions. However, whether it is a steel tubing system or aluminium frame, every option is manufactured to the highest demands.

Pile foundation system ALFREI_RAMM

Pile foundations are used for this one pillar system. This optimises longevity, material use and assembly eff ort required. The frame is connected with a prop head suitable for the occurring forces. This is manufactured specifi cally for the required module pitch. The foundation is especiallysuitable for soil classes 3 to 5. A ground survey confi rms the pile driveability and the required depth.

ALFREI_RAMM_BF(pile foundation system on concrete foundation)

This system off ers a creative solution as it combines the advantages of the pile founda-tion system with a concrete foundation. Using a matching counterpart (“base”) into which the pile can be inserted, allows the system to be used on ground which cannot be penetrated. In this case strip foundations are commonly used which off er the best possible material use. This also off ers the opportunity to use pre-existing concrete areas, such as on airports or barracks.
