Color coated steel plate, i.e. color steel plate, is a kind of steel plate whose substrate is cold rolled substrate, hot-dip galvanized substrate and electro-galvanized substrate.

Surface state can be divided into coated plate, embossed plate and printed plate, color coated steel plate is widely used in construction home appliances and transportation and other industries, for the construction industry is mainly used for steel structure plant, airport, warehouse and refrigeration and other industrial and commercial buildings such as the roof wall and door, civil construction using color steel plate is less.

The difference between it and plastic steel is that the composition of the material is different. Suction stone can be sucked .　Strictly speaking, plastic steel and color steel in the metal characteristics and surface treatment and can not be well distinguished, because much the same. Six characteristics of color steel plate: 1. light weight: 10-14 kg / square meter, equivalent to brick wall 1/302. thermal insulation and heat preservation: core thermal conductivity: λ <= 0.041w/mk. 3. high strength: can be used as a ceiling enclosure structure plate load-bearing, resistance to bending and compression; general housing without beams and columns. 4. color and lustre is bright: no need for surface decorations, color galvanized steel corrosion-resistant layer to maintain the period of 10-15 years. 5. flexible and quick installation: the color steel and the metal characteristics and surface treatment can not be distinguished, because the same big. 5. Flexible and quick installation: construction cycle can be shortened by more than 40%. 6. Oxygen index: (OI) 32.0 (Provincial Fire Products Quality Inspection Station). 7. The form of color steel plate: not formed before the coil, after the molding of the model is a lot, the most commonly used are: 820 type, 840 type, 900 type! Its composition structure is: protective film, polyester paint, galvanized layer, steel plate.
