1. Single pile support systems for free-fields
1.1
The single pile support system for free-fields is made from galvanized steel. The quality of the steel
finish has a minimum coating of hot dip galvanization 45 microns. The purlins can be either from
aluminium or galvanized steel. All of the steel accessories (bolts, nuts, etc...) are made from stainless
steel A2.
The system is available in 2 versions, 2 portrait & 3 landscape with angles of 25°,30°,35°.
The foundation of the system can be made with steel driven piles or with concrete piles.

2. Assembly of support system
The individual parts for assembling the support
system are provided with the necessary
machining for easier and faster installation.
2.1 PILE FOUNDATION
Pile driving should be performed by specialist,
and should be according to the installation
specifications and drawings.
The piles should be placed with the large
surface area parallel to the North-South axis.

The girder connector can be adjusted in
the vertical direction +/- 2cm
The girder beam can be adjusted in the
horizontal direction +/- 2cm

4. Installing purlins
Two types of purlins are available:
Ÿ Aluminium purlin ( SolarPrime)
Ÿ Steel purlin ( FUS62 )
4.1 ALUMINIUM PURLIN ( SolarPrime )
The aluminium purlin (Solar Prime) is fastened to the steel girder beam with the corner clamp
connector that is inserted into the channel on the side of the purlin and then it is fastened with an
allen screw and a safety nut M8 to the girder beam.

4.1.1 PURLIN CONNECTOR
When the purlin is used continuously to span over several girders, then a special purlin connector is
used to fasten the two purlins together. The purlin connector is inserted into the chamber of the
purlin and fastened with self-tapping stainless steel screws.

4.2.1 PURLIN CONNECTOR
When the purlin is used continuously to span over several girders, then a special purlin connector is
used to fasten the two purlins together. The purlin connector is fastened to the under side of the
purlin with four allen screws M12x30 and washers M12. Safety nuts are not required as the
connector has been threaded to directly receive the M12 bolts.

5. Installing the panels
The panels are fixed to the purlins
with special clamps. There are
end clamps that are used to fix
the panels at the beginning and
the end of a series, and there are
middle clamps that are used
between two panels.
The clamps are available preassembled (with allen screw,
spring, plastic grip, hammer-head
nut) and are availble for every
panel thickness.
The hammer head nut is inserted into the channel of the purlin and turned to lock into the desired
position.
Then the clamp is fastened into place with the allen screw.
