Product Description

Color Coated Steel is a kind of Coated & Painting Steels, which is made by using special steel substrates, after surface chemical pretreatment, coated with one or more layers of paints on the surface by roller coating method generally, and then baked and cooled, and finally output a kind of steel sheet product.


Since the product is coated with organic paints and usually has beautiful colors or patterns after it is produced, it is also called Organic Coated Steel, Color Coating Steel, Color Painting Steel or even Colored Steel or Color Steel.


The output products are usual in steel Coils shape, also could be provided in Sheets or Plates shapes, and could be further produced into other final using products by deep processing, which are also called Color Coated Steel Coils / Sheets / Plates, etc.


Such steel has no painting required in the subsequent production of various products, so it is also a kind of Pre-painted Steels or Pre-coated Steels.

FEATURES

Color Coated Steel is a new kind of steel material developing rapidly in recent 60 years all over the world. By using special steel substrates and coated in production line, the kind of output steel is composed of metal substrate, chemical conversion coating and organic painting, and has advantages of both organic polymer and steel plate.


Color Coating Steel undergoes chemical pretreatment, initial coating, final coating, and other processes in a continuous production line. The coating is uniform, stable, ideal, and much better than the individual spray coating or brush painting of particular shaped metal parts.


Color Steel has excellent properties of decoration, shaping, and good corrosion resistance. The coating adhesion is good and will not be changed for a long period. With the advantages of replacing wood, high construction efficiency, energy conservation, preventing pollution and good economic effects, the Color Coated Steel already becomes an ideal material in the construction & building area and also being widely used in other industries.
