Introduction of prepainted steel plate

Color-coated steel plate is made of cold-rolled steel strip and galvanized steel (electro-galvanized and hot-dip galvanized) as the substrate on the continuous unit. After surface pretreatment (degreasing and chemical treatment), it is coated with a layer by roller coating. Or multi-layer liquid coatings, which can be baked and cooled.

Introduction

Since the coating can have a variety of different colors, it is customary to call the coated steel plate a color coated steel plate. And because the coating is carried out before the steel plate is formed, it is called pre-coated steel plate in foreign countries.

Color coated steel plate is an organic coating applied to the surface of steel. It has the advantages of beautiful appearance, bright color, high strength, good corrosion resistance, convenient processing and forming, etc., and it can also reduce costs and reduce pollution for users.

Since the establishment of the first continuous coated steel plate line in the United States in 1935, color-coated steel sheets have been widely used. There are many varieties of color-coated steel sheets, about more than 600 kinds. Color-coated sheets have the advantages of both organic polymers and steel sheets. It has good coloring, formability, corrosion resistance, and decoration properties of organic polymers, and high strength and easy processing of steel plates. It can be easily processed by stamping, cutting, bending, and deep drawing. This makes products made of organic coated steel plates have excellent practicability, decoration, processability and durability.
