Color steel coil is a new type of material produced in recent years due to high-end applications in China, often referred to as CCLI. It is a product made of galvanized steel sheet (55% aluminum, 43% zinc and 1.6% silicon) with more corrosion resistance than zinc as a substrate after surface degreasing, phosphating, and complexing, and then coated with organic coatings by baking. Color difference MAX.2.

The above data show that zinc-aluminum coated sheet (AZ150, G345A, PVDF) is very suitable for extreme environments in the building or other facilities, with corrosion and weather resistance, and this steel plate major steel mills can guarantee more than 20 years of service life. In addition, high-strength steel plate has been commonly used in foreign countries, has a better economy, but also the development trend in China.

Hot zinc, hot zinc iron alloy, hot aluminum zinc alloy, hot aluminum alloy, electric zinc. The steel coils generally used are hot zinc and hot aluminized zinc. Appearance can not be distinguished, can only be seen through the volume of the outer packaging logo. Color steel coil substrate is hot zinc, hot zinc raw material is cold rolled sheet, with cold rolled sheet plated on top of a layer of zinc is plated volume, now zinc is generally hot zinc, electroplating is very little, so the steel coil is cold rolled sheet.

Appliances with coated steel coil in the shear uncoiling, the surface from time to time there will be a defect - the surface of the pressure spot defect, the defect is the color plate coating baking, cooling after coiling, due to the winding tension caused by the coating surface of the slight deformation, sometimes the surface shows a roughness, the performance of the visually visible form of the pressure spot. Quality in heat dissipation and high temperature resistance.

It also stands out in terms of color, finish, and feel. Focusing on the development of new coatings, we have improved general polyester, polyvinylidene fluoride (PVDF) and plastisol to obtain super color reproducibility, UV resistance, sulfur dioxide resistance, and improved corrosion resistance; and developed functional coatings such as pollution resistance and heat absorption.
