In recent years, with the development of color steel house industry, the demand of color steel house material color steel plate is also increasing.Color steel plate is a kind of very thin steel plate with organic color coating.Most of them are used for the wall panel and roof panel of the mobile room, which are used as the fence at the roadside and construction site.At present, there are large and small color steel plate manufacturers in the market, because of the different strength and technical level, it will also affect the quality of color steel plate.So how can we judge the quality of color steel plate?

The first is to observe the thickness of the substrate and peritoneum. The color steel plate mainly has the substrate and the color peritoneum or coating.In this way, the thickness of substrate and peritoneal coating should be considered when selecting color steel plate. The better color steel plate substrate is 0.02-0.05 mm, and the thickness of coating or coating is usually less than 0.15 mm. From the perspective of the service life of the color steel plate, the thickness of the substrate is also very important.However, some manufacturers of color steel plate often make hands and feet on the substrate and the coating or film of color steel plate. Once the thickness of the substrate is reduced, but the thickness of the peritoneum is increased to reduce the production cost of color steel plate, the service life of color steel plate will be greatly reduced.

The second is to observe the outer edge of the color steel plate. When getting a color steel plate, it is necessary to first observe whether the exposed steel of the color steel plate, such as the cross-section, is crystalline and dense, and whether there is gray, dark and impurities.If the section is crystal fine, then the quality is better.

The third is to judge by listening to the sound. If the material of color steel plate is poor, the sound will be dull. The metal sound is not obvious. The metal sound of color steel plate with good material is loud and clear.

Fourth, check the quality of color steel plate to confirm whether there are inspection standards for relevant parts.If the condition allows best can go to the manufacturer of color steel plate to undertake on-the-spot investigation, look at the environmental equipment of the enterprise how, whether formal.You can also learn about the reputation and reputation of color steel plate manufacturers in the market.Finally, through the price inspection, everything is a cent of goods.When comparing the quality of color steel plate, the price is only one aspect, and it is not necessary to pay too much attention to the price.But when the price of one kind of color steel plate is much lower than that of others, the friends who want to buy it must be considered
