Aluminium Solar Mounting Structures
L2 and L3 aluminium structures for flat roofs and open ground, where low weight and corrosion resistance matter most.

Where they are used and what they are made of
FERO L2 and L3 structures are made from anodized aluminium 6063 T5 with SS304 fasteners. They are used on concrete flat roofs and on open ground, where they add tilt to a flat surface. Aluminium is light, which helps on roofs with limited capacity, and it does not rust, so the structure needs no corrosion maintenance.
L2 is the modular baseline for typical flat roof and ground installations, and L3 is scaled for larger arrays and wider spans. Both run at a standard inclination of 10 to 45 degrees and a standard design wind speed of 35 m/s (126 km/h), and both are customized per project. For each site we set the tilt, member sizes, spacing and connection details from the roof or ground, the wind exposure, the number of modules and the access needed for cleaning. Where obstacles or shading limit a flat roof, an elevated shed is the alternative.

Common questions
When should I choose aluminium over galvanized iron?
Choose aluminium for roof structures where weight matters or where you want no corrosion maintenance. Galvanized iron suits ground mounts, shell roofs, elevated sheds and parking structures, where members span longer distances and carry more load. Your site, wind zone and span decide the final choice.
Which suits my roof, L2 or L3?
L2 is the modular baseline for typical flat roof and ground layouts. L3 is scaled for larger arrays and wider spans. We confirm the choice from your roof drawings and module count.
What tilt can the aluminium structures take?
The standard range is 10 to 45 degrees, and it can be customized per project.
