Color steel coil is more and more widely used in the society. It occupies an important position in the new construction that we attach importance to and bear, such as the movable plank house. Then the following problems are, for example, finding a color steel coil in many color steel plates. Next, let's look at some techniques of distinguishing colored steel plate summarized by Xiaobian.
First of all, we should check the quality certificate of the color steel plate, and whether there are relevant parts of the inspection specifications. Before purchasing, check the company's reputation and reputation in the market. Better yet, we can go to the producer of color steel plate to make a field trip to see how the environmental equipment of the company is and whether it is formal.
Only through the price can we know the quality of color steel plate products. Everything is a penny for a penny. When comparing the quality of coloured steel plate, the price is only on the one hand, and it does not need to pay too much attention to the price. However, the price of one kind of color steel plate is much lower than other cases, friends who want to buy will have to consider.
Investigate whether the exposed steel plate, such as cross-section, has fine crystallization, gray, dark and impurities. Assuming that the section is fine crystalline, the quality is better. To investigate the thickness of the base plate and peritoneum, the color steel plate is thick enough to have a base plate and colorful peritoneum or coating. The better color steel plate is 0.02-0.05 mm, and the coating thickness is usually less than 0.15 mm.
Somemanufacturers of color steel plate often make hands and feet on the base plate and the coating or coating of the color steel plate, reduce the thickness of the base plate, add the thickness of the peritoneum to reduce the production cost of the color steel plate, and to a large extent reduce the service life of the color steel plate. When the color steel plate is struck with finger or hard object, the metal sound of the color steel plate with better raw material is louder and louder. If the raw material of the color steel plate is assumed to be worse, the sound will be dull and the metal sound is not obvious.
