Color-coated steel panels are made by applying a coating (roll-coating) or composite organic film (PVC film, etc.) to cold-rolled steel sheets or galvanized steel sheets after surface chemical treatment, and then baking and curing them. Some people also refer to this product as "pre-roll-coated color steel" or "plastic color steel." Color steel products are produced in rolls on continuous production lines by manufacturers, hence also known as color coated steel coil. Color steel panels combine the high mechanical strength and ease of shaping of steel materials with the good decorative and corrosion-resistant properties of the coating material. Color steel panels are a new material highly regarded in today's world. With the advancement of technology, the increased awareness of environmental protection, and the improvement of people's living standards, color steel panel mobile houses are increasingly demonstrating their strong vitality and broad market prospects, and are favored by industries such as construction, home appliances, electromechanical, transportation, interior decoration, office supplies, and others.

Color-steel activity houses feature light weight, high strength, thermal insulation, aesthetics, durability, and are a quick installation solution that integrates architecture and decoration. These houses are easy to construct and maintain, widely used in large-span factories, warehouses, office buildings, villas, roof 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.
