Steel coil is widely used in the construction industry. Hot-rolled steel coil is often used in building structures, Bridges, ships, auto parts, appliances, home improvement, steel structure houses and pipelines, etc., to provide a strong foundation for construction. Cold rolled steel coils are used in the manufacture of steel structures, steel frames and steel plate facades, and their high strength, seismic performance and workability make them ideal building materials. In addition, stainless steel rolls are suitable for architectural decoration, such as wall panels, ceilings and floor panels, and their anti-corrosion and wear-resistant properties make them ideal for indoor and outdoor decoration. The color coated steel coil has excellent anti-corrosion and weather resistance, which can effectively protect the building from the influence of air pollution and oxidative corrosion, and extend its service life.
