Color steel plate coating is a product made by coating or laminating organic films (such as PVC film) onto cold-rolled steel or galvanized steel plates after surface chemical treatment, followed by baking and curing. Some people also refer to this product as "pre-coated color steel plate" or "plastic color steel plate." Color steel products are produced in rolls on continuous production lines, hence also known as color coated steel coil. Color steel plates 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 plates are a new material highly regarded in today's world. With the advancement of technology, the strengthening of environmental awareness, and the improvement of people's living standards, color steel plate buildings are increasingly demonstrating their strong vitality and broad market prospects, and are favored by the construction, home appliance, mechanical and electrical, transportation, interior decoration, office supplies, and other industries.

Color-steel activity houses offer advantages such as light weight, 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 the activity house construction.
