How To Judge Quality Of Color Coated Steel Sheet?

Released on Sep. 11, 2018

1. Observe the thickness of the substrate and the thickness of the film. The Color Coated Steel Sheet is composed of a substrate and a colored peritoneum or plating. We must first consider the thickness of the substrate and the peritoneal coating. The better color steel plate substrate is 0.02~0.05mm, and the thickness of the coating or coating is often only 0.15mm or less. The thickness of the substrate is important because it affects the use time of the color steel plate.

2. Observe the outer leakage edge of the Color coated steel coil. When I get a piece of color steel plate, I first observe whether the exposed steel plate, such as the section, is crystallized and fine, whether it is gray, dark and impurities. If the cut surface is crystalline and fine, the quality is superior.

3. Listen to the 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.

4. Look at the price. Anything is a penny. When we compare the quality of color steel plates, the price is one side, but don't pay too much attention to the price. If the price of a color steel plate is much lower than the others, then we have to pay attention.

5. Check the quality certificate of the color steel plate. Is there a test standard for the relevant department? If possible, try to go to the manufacturer of the color steel plate for field visits. Look at the environment of the company, whether it is formal.
