H PROFILE FOR 4mm. AND 6mm. POLYCARBONATE. 6m. LENGTH. With a length of 6m, equal to the side of the plates, it serves to hermetically join two plates. It is a safe and easy-to-install system, allowing two plates to be joined on the side, preventing the entry of water or dust. The system also makes it easy to leave a small distance for dilations. The profile is placed manually or with a rubber hammer so as not to damage it, with slight pressure. Fix the two plates and their intermediate part can be used to screw with self-drilling screws, fixing to the wooden or metal structure that serves as a support. In our blog you can see the montage.
