For the current construction market, there are many new types of building materials, but the diversity of colored steel plate makes it gradually become a popular choice. It is important that it can meet people's needs in all aspects. Because people are demanding more and more building materials, people should pay attention to their quality problems when they buy them, so it is very important to learn how to judge their quality.

 

Observe the thickness of substrate and coating: The color plate consists of substrate and color peritoneum or coating. We need to consider the thickness of the substrate and the peritoneal coating. Better steel substrates range from 0.02 mm to 0.05 mm, and coatings or coatings are usually less than 0.15 mm thick. The thickness of the substrate is very important in affecting the use time of the color plate. The color steel plate on some substrates is usually laminated or laminated with the color steel plate to reduce the thickness of the substrate, but the thickness of peritoneum increases to reduce the production cost of the color steel plate, which greatly reduces the service life of the color steel plate.

 

Observe the leak edge of the coloured steel plate: When a coloured steel plate is taken, observe whether the exposed steel, such as the section, crystallizes fine, gray, dark and impurities. If the cutting surface is crystal clear, the quality will be better.

 

Listen: Knock the color steel plate with your fingers or with good things. If the material of the color steel plate is bad, the sound is dull, the metal sound is not obvious, and the sound of the good color steel plate metal is loud and clear.

 

In a word, color steel plate is a new building material, which has good environmental protection function and is widely used in roofing, wall, temporary housing and so on.
