In February 2021, the solar power specialist LORENZ ENERGIE GmbH installed a 100 kWp solar power system on the green roof of the Berkesheimer School in Frankfurt am Main.
The quick and easy to install flat roof system TRIC F Duo East/West 10° was chosen as the mounting system.
In this case the TRIC F duo system was fixed on concrete blocks using our new concrete screw Quick. This screw renders anchors or dowels obsolete.

Concrete screw Quick

Did you know? TRIC F duo on gravel or green roofs - no problem at all! Simply use our new concrete screw Quick for simple, safe and fast fixation of Duo ground rails on concrete blocks. The concrete screw is screwed directly into a pre-drilled 6 mm hole without dowels and it can be loaded instantly. The special thread, with toothed and hardened front section, cuts its own internal thread into the building material while screwing it in. It can even be used close to the edge without a torque wrench and is easily dismantled if required.
