How To Choose Color coated roofing sheet?

Released on Aug. 20, 2018

1. Observe the outer leakage edge of Color coated roofing sheet

When I get a sandwich panel, I first observe whether the exposed steel plate such as the cross section of the color steel plate is finely crystallized, whether it is gray, dark and impurities. If the cut surface is crystalline and fine, the quality is superior.

2. listening to color steel sandwich panel sound

If you use a finger or a hard object to strike the color steel plate, if the material of the color steel plate is poor, the sound that is emitted is boring, the metal sound is not obvious, and the metal sound of the material with good quality is relatively loud and crisp.

3. Observe the thickness of the substrate and the thickness of the film.

The color steel sandwich panel from Color coated steel coil factoryis composed of a substrate and a colored peritoneal or plated layer. First of all, we have to consider the thickness of the substrate and the coating. The better color steel plate is 0.02~0.05mm, and the thickness of the coating or coating is usually only 0.15mm.

4. check the quality certificate of color steel sandwich panel
