Color-coated steel panels are products made by coating or laminating an organic film (such as PVC) onto cold-rolled steel or galvanized steel sheets after undergoing surface chemical treatment, followed by baking and curing. Some also refer to this product as "pre-coated steel panels" or "plastic-coated steel panels." Color-coated steel products are produced in rolls on continuous production lines, hence also known as color-coated steel coil. These panels combine the high mechanical strength and ease of forming of steel materials with the good decorative and corrosion-resistant properties of the coating material. Color-coated steel panels are a new, highly regarded material in today's world. With the advancement of technology, increased environmental awareness, and improved living standards, prefabricated steel panels are increasingly demonstrating their strong vitality and vast market prospects, enjoying popularity in the construction, household appliances, mechanical and electrical, transportation, interior decoration, office supplies, and other industries.

Color-steel activity houses offer advantages such as lightweight, high strength, thermal insulation, and aesthetic durability, seamlessly integrating architecture and decoration for quick installation. These structures are easy to clean and widely used in large-span factories, warehouses, office buildings, villas, rooftop extensions, clean rooms, cold storage, shops, kiosks, and temporary housing. The lightweight color-steel sandwich panels, weighing less than 14 kg per square meter, can significantly reduce structural load and lower the cost of activity house construction.
