How can I Judge the Quality of Color Steel Plate
Color steel plate is an important part of the steel structure envelopment system, and its quality plays an important role accordingly. No.1 Method, observe the thickness of the substrate and the thickness of the laminate. Color steel plate is composed of the substrate and the colored laminating film or coating. We first have to consider the thickness of the substrate and lamination and coating, the better color steel substrate is 0.02-0.05mm, and the thickness of the lamination or coating is often only 0.15mm or less. Because of the influence of the color steel plate use time point of view, the thickness of the substrate is very important. But some manufacturers make changes on the substrate and color steel plate coating or coating, they reduce the thickness of the substrate, but increase the thickness of the peritoneal membrane to reduce the production cost of the color steel plate, which greatly reduces the service life of the color steel plate. the process of color steel pla
