Color steel sheet coating is a product made by coating (roll-coating) or bonding organic film (PVC film, etc.) on cold-rolled steel sheets or galvanized steel sheets after surface chemical treatment and baking curing. Some people also refer to this product as "pre-roll-coated color steel sheet" or "plastic color steel sheet". Color steel products are produced in rolls on continuous production lines by manufacturers, hence also known as color coated steel coil. Color steel sheets combine the high mechanical strength and easy moldability of steel materials with the good decorative and corrosion-resistant properties of the coating material. Color steel sheets are a newly promoted material in today's world. With the advancement of technology, increased environmental awareness, and improved living standards, the life force and market prospects of color steel activity houses are increasingly evident, and they are favored by industries such as construction, home appliances, machinery and electronics, transportation, interior decoration, office supplies, and others.

Color-steel activity houses offer the advantages of lightweight, high strength, thermal insulation, and aesthetic durability, seamlessly integrating architecture and decoration for quick installation. They are widely used for large-span factories, warehouses, office buildings, villas, rooftop extensions, clean rooms, cold storage, shops, kiosks, and temporary housing. The lightweight color-steel sandwich panels, with a weight per square meter under 14KG, can significantly reduce structural load and lower the cost of activity house construction.
