Metehe Rivikatto (row roof) lock seam sheet metal is manufactured with a 35 mm high lock seam using 0.60 mm warranty-coated steel sheet metal. The surface of the Rivikatto SRT 35 model is smooth and the surface of the Rivikatto WRT 35 model has stiffening ribs. The installation screws remain hidden in both models, and the ready-made edge fold finishes the installation of the front edge. The roofing is well-suited for more gently sloped sites, and the product can easily be installed by yourself. The coating options are PUR, PUR Matte (technical warranty 50 years) and HC25 (technical warranty 40 years).
