The coated steel sheet is a product made by coating (roll coating) or laminating organic films (such as PVC film) 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-coated steel sheet" or "plastic coated steel sheet." The colored steel sheet products are produced in rolls on a continuous production line by the manufacturer, hence also known as colored coated steel sheet rolls. Colored steel sheets combine the high mechanical strength and easy molding properties of steel materials with the good decorative and corrosion-resistant properties of the coating material. Colored steel sheets are a newly promoted material in today's world. With the advancement of technology, the enhancement of environmental awareness, and the improvement of people's living standards, the colored steel sheet activity houses are increasingly showing their strong vitality and broad market prospects, gaining favor in the construction, home appliance, electromechanical, transportation, indoor decoration, office supplies, and other industries.

Color-steel panel mobile houses offer advantages such as lightweight, high strength, thermal insulation, and aesthetic durability, seamlessly integrating architecture and decoration for quick installation. These houses are easy to construct and maintain, 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 mobile house construction.
