One: Check the thickness of the substrate and the thickness of the film
Color steel plate is composed of substrate and colorful peritoneum or coating. 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 usually less than 0.15mm. Since the thickness of the substrate is very important from the perspective of affecting the use time of the color steel plate. However, some manufacturers of color steel plates often play tricks on the substrate and the coating or film of the color steel plate. They reduce the thickness of the substrate, but add the thickness of the peritoneum to reduce the production cost of the color steel plate, which reduces the service life of the color steel plate.
Two: Check the leakage margin of the color steel plate
When I get a color steel plate, I first investigate whether the exposed steel of the color steel plate, such as the section, is finely crystallized, and whether it is gray, dark, or impurity. If the cut surface is finely crystalline, the quality is superior.
