1. The quality of colour coated galvanized steel is decided by the basic function of base material and coating. And it’s also decided by production technology and operation and control skill. Operation and control skill greatly impact the physical function and appearance of colour coated galvanized steel products. The point of coil quality includes four links: cleaning treatment, chemical coating treatment, coating and solidification according to production technology.
2. The production of color coated coil adopts double coating-double drying technology. To ensure the quality of coating layer, it’s necessary to conduct earlier stage processing on the appearance of base material. Such as oil removing, dust extraction and rust cleaning. The process of color-coated coil treatment is to first remove the anti-rust oil, rust and dust adhere to the surface. And then conduct chemical coating treatment on clean surface. To increase the adhesiveness between base material and coating layer and improve the corrosion resistance of base material and the durability of coating layer.
3. Production quality decides coating quality. And production quality directly impacts the physical indexes of coating layers including flexibility and impact resistance. As well as it decides the adhesiveness of coating layer of color-coated coil and color coated plate products. The process of prime coating,finish coating and solidification is to coat the coating on the board of base material and make the coating organic solvent evaporate by heating, so as to let the organic coating layer closely combined with base material.
The color coated steel coil of CAMELSTEEL has a strict quality supervision department to control the quantity of coil, please assure that, steel coil is camelsteel, camelsteel is steel coil.
