How to judge the quality of color coated rolls
For the current construction market, there are many new types of building materials, but the diversity of color-coated rolls makes it gradually become a popular choice. The important thing is that it can meet people's needs in all aspects. As people's requirements for building materials are getting higher and higher, people should pay attention to quality issues when purchasing building materials, so how to judge the quality of building materials is very important.
Color Coated Roll 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 peritoneal coating. Better steel substrates range from 0.02 mm to 0.05 mm, and the coating or coating thickness is usually less than 0.15 mm. The thickness of the substrate has a very important influence 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 drain 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: Hit the color steel plate with your fingers or something good. The color steel plate is of poor material, the sound is dull, the metal sound is not obvious, and the color steel plate metal sound is loud and clear.
To sum up, color-coated roll is a new type of building material with good environmental protection functions and is widely used in roofs, walls, temporary houses, etc.
