Color steel plate refers to color steel plate, which is a kind of steel plate with organic coating. It is divided into veneer, color steel composite board, floor bearing board, etc. Color steel plate substrates are cold-rolled substrates, hot-dip galvanized substrates, and electro-galvanized substrates. Coating types can be divided into polyester, silicon modified polyester, partial polyvinylidene fluoride and plastisol. The surface state of color steel plate can be divided into coated plate, embossed plate and printing plate.
