At present, there are many new building materials in the construction market, but the diversity of color steel plate makes it gradually become a popular choice, and more importantly, it can meet people’s various needs. As people’s requirements for building materials are getting higher and higher, when people buy building materials, they still need to pay attention to its quality, so how to judge its quality is very important.
Substrate and coating thickness: Color steel plate is composed of substrate and bottom plate or bottom plate. The thickness of the substrate and peritoneal layer should be taken into account. Between 0.02 and 0.05 mm, the thickness of a good steel substrate and coating generally does not exceed 0.15 mm. The thickness of the substrate has a big impact on how long the swatches will last. The color steel plate on some negatives is generally layered or laminated with the color steel plate, which reduces the thickness of the bottom plate, but the thickness of the bottom plate increases, which reduces the production cost of the color steel plate, thus greatly shortening the service life of the color steel plate.
Observing the leaking edge of the color steel plate: When taking the color steel plate, it is necessary to observe the exposed steel sheet, such as section, grain fineness, grayscale, color, etc. If the cut surface is crystal clear, the quality is good.
