Color steel plate coatings are products 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-roll coated color steel plate" or "plastic color steel plate." Color steel products are produced in rolls on continuous production lines by manufacturers, hence also known as color coated steel coil. Color steel plates combine the high mechanical strength and easy molding properties of steel materials with the good decorative and corrosion-resistant properties of the coating material. Color steel plates are a new emerging material highly regarded in today's world. With the advancement of technology, increased environmental awareness, and the improvement of people's living standards, color steel plate activity houses are increasingly demonstrating 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 sandwich panel mobile houses offer the advantages of lightweight, high strength, thermal insulation, and aesthetic durability, seamlessly integrating architecture and decoration for quick installation. These mobile houses are easy to construct with cleanliness, and are widely used in large-span workshops, warehouses, office buildings, villas, roof extensions, clean air rooms, cold storage, shops, kiosks, and temporary housing. 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.
