Steel caps with seal
Steel cap with metallic coatings to facilitate the expansion and shrinkage of sheet metal.
The purpose of mounting screws is to fasten and join sheet metal to various substrates . They can be self-engraved and with different processing of the tips, in different colors or in a raw design.
The screws differ from each other depending on the intended use (roofing, facade, metal products, borders, etc.) and the intended substructure (wood, metal, etc.). We know:
Screws of this type enable the fastening of roof and facade panels to a wooden or metal substructure. The screws for the panels, which are most often used, are stainless steel (INOX) and have a seal made of high-quality EPDM rubber, which is resistant to all external influences. Depending on the fastening method, we distinguish between self-drilling screws and wood screws or metal construction with pre-drilling .
Screws for metal roofing without insulation are fully galvanized in the color of the roofing, with a hexagonal head with a steel washer with an EPDM seal, or stainless steel (INOX), which also have a seal made of high-quality EPDM rubber. The screws are of different lengths and are suitable both for screwing into wooden and metal structures .
Carpenter screws are used to fasten sheet metal or plastic materials to wooden structures or together with inserts for fastening to hard surfaces. They have a weather-resistant sealing washer and are available in different colors and lengths.
Screws for clamps allow us to attach drain pipes to the facade . The screws are available in standard lengths between 80 and 150 millimeters, but there is the possibility of adjusting the screws according to the thickness of the facade between 80 and 400 millimeters.
Hanger screws for clamps are not very different from ordinary ones, except for their torx system . The standard lengths are the same as for ordinary screws, and the flexible lengths of these screws are between 80 and 300 millimeters.
Riders are used when installing roof coverings on profiled sheets. Their task is to mitigate the expansion and contraction of the sheet metal , as this also allows the screw to have a greater inclination. The advantages of the riders are that they enable safer installation of roof coverings , high structural strength and optimal pressure distribution. They are available in different colors that match the colors of the coverings, and in different widths.
Roofing and carpentry tools enable roofers to perform their work efficiently and effectively . These tools include a puncher, hammer, pliers, pliers, various scissors, benders, etc.
