Description
Aluminium Trapezoidal PV Bridge with EPDM H70 L330 for Trapezoidal Sheet Roofs
Aluminium trapezoidal bridge H70 L330 is a robust mounting profile designed for photovoltaic installations on roofs covered with trapezoidal sheet metal. Thanks to the 2 mm EPDM gasket, it ensures a tight and stable contact with the substrate, eliminating the risk of micro-vibrations and damage to the sheet coating. The ready-made component reduces installation time and ensures consistency across every roof.
The profile is manufactured from aluminium with a Standard finish (protective anodising). The trapezoidal cross-section with a central guide channel allows secure fastening with a bolt or self-drilling screw and guarantees high load capacity with a low self-weight of just 0.357 kg.
Application
- Mounting PV rails on trapezoidal sheet metal roofs
- Compensation of the trapezoid profile – the bridge distributes pressure evenly across the sheet corrugations
- Compatible with self-drilling screws or bolts with EPDM washers
