Color steel plate refers to color-coated steel plate, which is a kind of steel plate with organic coating. Color steel plates are divided into single plates, color steel composite plates, floor decks and so on. It is widely used in the wall and roof of large public buildings, public factories, prefabricated houses, and integrated houses.
1: Observe the thickness of the substrate and the thickness of the coating
The color steel plate is composed of a substrate and a colored peritoneum or coating. We must first consider the thickness of the substrate and the peritoneal coating. The better color steel plate substrate is 0.02~0.05mm, and the thickness of the coating or coating is often only 0.15mm or less. Because the thickness of the substrate is very important from the perspective of affecting the use time of the color steel plate. And some manufacturers of color steel plates tend to make hands and feet on the substrate and the color steel plate coating or film. They reduce the thickness of the substrate, but increase the thickness of the peritoneum to reduce the production cost of the color steel plate, which greatly reduces the use of the color steel plate. Life is over.
2: Observe the leakage edge of the color steel plate
When I get a color steel plate, I first observe whether the exposed steel such as the cross section of the color steel plate is finely crystallized, whether it is gray, dark, and impurities. If the cut surface is of fine crystallinity, the quality is superior.
3: Listen to the sound
Tap the color steel plate with your fingers or with a hard object. If the material of the color steel plate is poor, the sound will be dull, the metal sound is not obvious, and the metal sound of the color steel plate with better material is relatively loud and crisp.
4: Check the quality certificate of the color steel plate
Whether there are inspection standards of relevant departments. If possible, try to visit the color steel plate manufacturer on site. See how the business environment is and whether it is formal. Ask about the reputation of this company in the market.
5: Look at the price
Everything you pay is what you pay for. When we compare the quality of color steel plates, the price is one aspect, but we should not pay too much attention to the price. If the price of a color steel plate is much lower than others, then we must pay attention to it.
