Color coated roll to observe the thickness of the substrate and coating: The swatch consists of the substrate and the colored peritoneum or coating. We need to consider the thickness of the substrate and the peritoneal coating. Better steel substrates range from 0.02mm to 0.05mm, and the coating or coating thickness is usually less than 0.15mm. The thickness of the substrate has a very important impact on the service time of the swatch. Color steel plates on some substrates are usually compounded or laminated with color steel plates to reduce the thickness of the substrate, but the thickness of the peritoneum is increased to reduce the production cost of color steel plates and greatly reduce the service life of color steel plates. plate.
Observe the leakage edge of the color steel plate: When taking the color steel plate, observe whether the exposed steel plate, such as the section, has fine, gray, black, and impurity crystals. If the cutting surface is crystal clear, the quality will be better.
Listen: tap the color steel plate with your fingers or something good. The color steel plate is made of poor material, the sound is dull, the metal sound is not obvious, and the color steel plate metal sound is loud and clear.
In summary, color coated roll is a new type of building material with good environmental protection functions and is widely used in roofs, walls, and temporary houses.
