CALCULATEHEAVY-DUTY STRUCTURE – Aluminium and steelA structure you can rely on, without compromise
Soltrek: No “plastic kits”. Just solid steel, aluminium and bolts.
While most current mounting systems for flat roofs focus on speed and fragile plastic snap-fit components, at SOLTREK we believe in solid, proven materials. Our structure is made exclusively from solid steel and aluminium, securely joined with bolts. No plastic. Once assembled, it will last on the roof much longer than the solar panels themselves.
Where does Soltrek refuse to compromise?
- 100% plastic-free: The entire structure is made exclusively from solid aluminium and sturdy 0.8 mm galvanised sheet metal.
- Strength that stays in place: All key parts — trays, brackets and wind deflectors — are securely fastened with steel bolts. This creates a strong yet flexible assembly that reliably withstands thermal expansion and extreme wind gusts.
- Roof protection for 50 years: The underside of the ballast trays is fitted with an integrated 3 mm EPDM rubber strip. It does not chemically deform roof membranes and reliably dampens wind-induced vibrations.
- Time efficiency: Assembly takes slightly longer than snapping plastic together, but the integrated tray lets you load concrete ballast directly into it in no time. No additional ballast holders need to be purchased or fitted.

Detailed description of the mounting components
Solar rail
Installed on the roof brackets to secure photovoltaic panels using end and mid clamps. Material: aluminium. Length: 3000 mm.
Ballast tray
A specially shaped component attached to each roof bracket with two bolts. It provides a simple way to secure the structure with ballast. The required number of 300×300 mm concrete paving slabs is placed inside the tray. The ballast requirement is calculated individually for each structure according to the roof type and height and the local weather conditions. The tray also protects the roof covering from damage caused by the aluminium bracket or ballast.
Rear wind deflector
Installed at the rear of the aluminium roof bracket. It protects the structure in adverse weather conditions and is also a design feature of the mounting system.
Side wind deflector
Installed on the outside of the end aluminium brackets.
The mounting system includes certification, a structural assessment and load calculations for the steel and aluminium components.
