Title Select High Quality Color Steel Sheet
Description First, color steel substrate thickness The high-quality color corrugated steel sheet is composed of substrate and color peritoneum or lamella. We must first consider the thickness of the substrate and peritoneal coating. The better color steel substrate is 0.02~0.05mm, the thickness of lamination or coating is usually only 0.15mm. The thickness of the substrate is important because it can affect the service life of colored steel sheets. Some color steel plate manufacturers often cut corners on the substrate and color steel coating or laminating. They reduce the thickness of the substrate, but increase the thickness of the peritoneum, reduce the production cost of color steel sheet, greatly reduce the service life of color steel sheet Second, the outer edge of the color steel sheet When you get a color steel sheet, first observe the color steel sheet cross-section exposed whether the steel sheet is fine crystallization, is gray, black and impurities. If the cut surface crystal and fine, excellent quality. Third, the price of color steel sheet You get what you pay for. When we compare the quality of color steel sheet, high-quality color coated corrugated roof board price is one thing, but do not pay too much attention to the price. If the price of color steel plate is much lower than other steel sheets, then we must pay attention to. Four, color steel quality certificate Does the relevant department have testing standards? If possible, please try to color steel sheet manufacturers on site. Look at the environment of the company, whether normal. Ask about the company's reputation in the market. Fifth, listen to the voice If the fingers or hard objects hit color steel sheet, if the color steel sheet material is poor, the metal sound is not obvious. The louder the metal, the better the color. Color steel sheet is louder, more relaxed.
