What is the color steel plate? Color steel plate, namely color coated steel plate, commonly known as color steel plate, is a steel product made of cold rolled steel plate, electro galvanized steel plate, hot galvanized steel plate or aluminum zinc plated steel plate after surface degreasing, phosphating, complexing treatment and transformation, coated with organic paint and baked.
The commonly used coatings for color steel plates are polyester (PE), followed by silicon modified resin (SMP), high weather resistant polyester (HDPE), polyvinylidene fluoride (PVDF), etc. The coating structure is divided into two layers of coating, one layer of baking and two layers of baking. The coating thickness is generally 20-25u on the surface, 8-10u on the back, and the external use of buildings should not be less than 20u on the surface and 10u on the back.
Color steel plate has the characteristics of light weight, high strength, bright color and good durability. Color steel plate is widely used in construction, household appliances, decoration, automobile and other fields.
The strength of color steel plate depends on the substrate material and thickness, and the durability depends on the coating (zinc plating amount 318g/m2) and surface coating. The coating is made of polyester, silicone resin, fluorine resin, etc. The coating thickness is more than 25um. The coating structure has two coats and one bake, two coats and two bake, etc. The maintenance free service life can be 20-30 years depending on the ambient atmosphere.
The commonly cited standards for color steel plate are ASTM A527 (galvanized), ASTM AT92 (aluminum zinc plated), JIS G in Japan, EN/ in Europe, KS D in South Korea, and Baosteel Q/BQB420.

Colour steel plate, also called coloured steel plate or coated steel plate, is a kind of metal plate with a colour coating, usually made from steel plate after a series of processes. There are many types of colour steel plate, the following are some common types of colour steel plate:
Single-layer colour steel plate: usually covered by a layer of colour coating on the substrate steel plate, suitable for some basic building applications.
Composite colour steel plate: covered by two or more layers of coating on the base material steel plate, it can provide better performance of heat preservation, heat insulation and anti-corrosion, etc., and is suitable for occasions with higher requirements for building heat preservation.
Rock wool colour steel plate: in the colour steel plate is sandwiched with rock wool and other thermal insulation materials, has excellent heat preservation and insulation properties, widely used in industrial plants, cold storage, etc..
Polyurethane colour steel plate: polyurethane foam is sandwiched in the colour steel plate, which has good heat preservation and insulation performance, and is suitable for occasions requiring heat preservation.
EPS colour steel plate: polystyrene foam is sandwiched in the colour steel plate, lightweight and good heat preservation, commonly used in buildings, cold storage, etc..
Mineral wool colour steel plate: in the colour steel plate is sandwiched with mineral wool and other heat preservation materials, has good heat insulation and heat preservation performance.
Fireproof colour steel plate: in the colour steel plate to join the fireproof material, has the good fireproof performance, usually used in the fireproof requirement high occasion.
Anti-static colour steel plate: the surface of colour steel plate is covered with a layer of anti-static coating, applicable to the static requirements of higher occasions, such as electronic plant.
Galvanised colour steel plate: the surface is galvanised with excellent anti-corrosion performance, usually used in environments requiring corrosion resistance.
PVDF coated colour steel plate: the surface is coated with PVDF resin, with excellent weather resistance and chemical stability, commonly used in high-grade buildings.
