The extrusion is made from high quality aluminum (also available in a double-anodized version) is designed for flexible or rigid LED strips that are 8 - 10 mm wide. One of the accessories offered for the extrusion are covers that shade and protect LEDs inside the profile. Covers are made of polycarbonate and additionally, they are certified for excellent resistance to all weather conditions or UV radiation as well as being flame retardant. Extrusion HR-ALU, together with LEDs, cover and caps should be used only in a version specially sealed with neutral silicone (recommended SIKASIL WS-605 S). Regarding the degreasing of surfaces, we recommend Universal Cleaner R-40 by DOW CORNING. The use of other agents can cause gaping or damage to the fixture. The extrusion is fastened to the desired surface, usually between ceramic tiles, with mounting adhesive. The design and parameters of the extrusion’s cover, when mounted in the floor, allows standard loads and performance of maintenance and utility works.
