Color steel plate coatings are products made by coating or laminating organic films (such as PVC) onto cold-rolled steel sheets or galvanized steel sheets after surface chemical treatment, followed by baking and curing. Some 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 easy formability of steel materials with the good decorative and corrosion-resistant properties of the coating material. Color steel plates are a newly promoted material in today's world. With the advancement of technology, increased environmental awareness, and the improvement of people's living standards, color steel plate buildings are increasingly demonstrating their strong vitality and broad market prospects, gaining favor in industries such as construction, home appliances, electromechanical, transportation, interior decoration, office supplies, and others.

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 clean in construction 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.
