Shandong Color Coated Plate, Color Steel Plate Manufacturer

Color steel plates have gradually been widely used. Today, we will analyze in detail how to distinguish the quality of color steel plates:

1: Observe the substrate thickness and coating thickness of the color steel plate, which is composed of a substrate and a colored peritoneum or coating. We first need to consider the thickness of the substrate and peritoneal coating. A better color steel plate substrate is 0.02-0.05mm, and the thickness of the film or coating is often only below 0.15mm. Because the thickness of the substrate is very important in terms of its impact on the service life of the color steel plate, and some manufacturers of color steel plates often manipulate the substrate and the coating or lamination of the color steel plate. They reduce the thickness of the substrate, but increase the thickness of the peritoneum to reduce the production cost of the color steel plate, which greatly reduces the service life of the color steel plate.

2: Listening to the sound, use your fingers or a hard object to strike the color steel plate. If the material of the color steel plate is poor, the sound produced is dull, and the metal sound is not obvious. The metal sound of the color steel plate with better material is relatively loud and crisp.

3: Observe the outer edge of the color steel plate and obtain a piece of color steel plate. We need to first observe whether the exposed steel, such as the cross-section, is finely crystallized, and whether it is gray, dark, and impurities. If the cut surface is crystalline and dense, it is of superior quality.
