The process characteristics of color coated steel sheets (Part One)

Due to the coatings on the surfaces of color coated steel sheets, it’s very different with the common rolled sheets. For the mechanical property and coating performance which has a big influence on color coated steel sheets, the technicists in CAMELSTEEL thinks it is very important to notice the following points during the processing:

1. If the parts’ shapes are complex and has a big deformation extent, people should use multi-pass forming. If it takes shape one time, maybe the big distortion will destroy the coatings’ adhesive power.

2. People should make the suitable gap according to the mold shape, distortion characteristic and technological conditions. And people should consider the thickness of color coated steel sheets coating.

3. People should set the rational process speed according to equipment states, technological conditions and part shapes. The over speed distortion will cause coating flake.

If the temperature is low, the flexibility of color coated steel sheets will cut down. So it is better to avoid  low-temperature working.

CAMELSTEEL consistently carry out the policy of “Customer first, employees of the second, third shareholders” and the tenet of “Treat people with sincerity, start business with trustiness”. We insist brand building of main line, market demand oriented, not afraid to innovate, keep providing the first-class service and quality products for customers indeed.
