Color steel plate is a new material composed of two-layer formed metal panel and polymer insulation inner core foamed and matured directly in the middle of the panel. Because of its light weight, heat insulation, high strength, bright color, flexible installation and short construction cycle, it is favored by the construction industry and is widely used in long-span plants, warehouses, office buildings, roof adding floors, shops and temporary buildings.
1. Listen to the sound and identify the quality. Knock the color steel plate with your fingers or hard objects. If the material of the color steel plate is poor, the sound is dull and the metal sound is not obvious. The metal sound of the color steel plate with better material is loud and crisp.
2. Check the quality certificate of color steel plate and whether there are inspection standards of relevant departments. If possible, try to go to the manufacturer of color steel plate for field investigation. Look at the environment of the enterprise and whether it is formal. Ask about the reputation of this enterprise in the market.
3. Observe the leakage edge of the color steel plate and get a color steel plate. I first observe whether the exposed steel of the color steel plate, such as section, is fine and dense, gray, dark and impurities. If the section is fine crystalline, the quality is superior.
4. Observe the substrate thickness and coating thickness. The color steel plate is composed of substrate and color peritoneum or coating. We must first consider the thickness of substrate and peritoneal coating. A better color steel plate substrate is 0.02 ~ 0.05mm, and the thickness of coating or coating is often less than 0.15mm. Because the thickness of the substrate is very important in terms of affecting the service time of the color steel plate. However, some manufacturers of color steel plate often do tricks on the substrate and color steel plate coating or coating. They reduce the thickness of the substrate, but increase the thickness of the peritoneum to reduce the production cost of color steel plate. Color steel plate manufacturers share the quality of color steel plate, which greatly reduces the service life of color steel plate.
