Color steel sheet coatings are made by cold-rolled steel sheets and galvanized steel sheets, which are coated (roll coated) or compounded with organic film (PVC film, etc.) after surface chemical treatment, and then baked and cured to form the product. Some people also call this product "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 ease of shaping 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, the enhancement of environmental awareness, and the improvement of people's living standards, color steel sheet buildings are increasingly demonstrating their strong vitality and broad market prospects, and are favored by the construction, household appliances, electromechanical, 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 houses are easy to construct and maintain, widely used in large-span factories, warehouses, office buildings, villas, rooftop extensions, clean rooms, refrigerated warehouses, shops, kiosks, and temporary accommodations. The lightweight color-steel sandwich panels, weighing less than 14KG per square meter, can significantly reduce structural load and lower the cost of activity house construction.
