Color steel plate is a very thin steel plate with organic color coating. Wall panels and roof panels, which are mostly used in mobile homes, are used on the roadsides and on construction sites as girders. In recent years, with the development of the mobile housing industry, the demand for color steel plates for movable houses has also increased. Currently, there are many manufacturers of color steel plates on the market. Due to the difference in strength and technical level, the quality of color steel plates will also be affected. In this case, how should we determine the quality of the active house color plate?
1, first of all to check the quality of the color steel plate confirmed that there is no relevant part of the inspection standard. Before the purchase, it is best to investigate the company's reputation and reputation in the market. It is best to be able to visit the manufacturer of the color steel plate to see if the company's environmental equipment is suitable or not.
2, only through the price can also know the quality of color steel plate product is good or bad, everything is a penny a point of delivery. When comparing the quality of the color plate, the price is only one of them, and it is not necessary to pay too much attention to the price. However, if the price of a color steel plate is much lower than that of other color plates, friends who want to buy it must be considered.
3. Observe whether the color steel plate exposed steel, such as the cross-section, is crystal-clear and has no graying, darkening and impurities. If the cut surface is fine crystalline, then the quality is relatively good. Observe the thickness of the substrate and the thickness of the peritoneum. The color-coded steel plate is mainly based on solid substrates and colored peritoneum or plating. The better color plate substrate is 0.02 to 0.05 mm, and the thickness of the coating or coating is often only 0.15 mm or less. Some manufacturers of color steel plate are often used on the substrate and color steel plate coating or coating to reduce the thickness of the substrate, increase the thickness of the peritoneum to reduce the production cost of the color plate, and greatly reduce the service life of the color plate. .
4, with the finger or with a hard object to hit the color plate, the material is relatively good color steel metal sound is relatively loud, crisp, if the material of the color plate is poor, the sound will be sent out of boredom, metal sound is not obvious.
