The standing seam clamps from Roofing Depot vary with regard to the material used, all providing different benefits that cater to the varying needs of roofing. Stainless steel, aluminum, and galvanized steel are common materials used for making standing seam clamps. Stainless steel is one of the favorite materials because it has excellent resistance to corrosion and rusting, so it is used for metallic roofing in coastal areas and with a lot of humidity. Aluminum clamps are highly resistant to corrosion and are very light, so installation is easy. Galvanized steel clamps are again cost-effective and do not compromise on strength and durability. They often feature a layer of zinc to help avoid rust and wear, making them suitable for a wide range of roofing applications.
