Color steel plates are divided into single-layer color steel plates and sandwich color steel plates. Generally, houses built with color steel plates can only see the surface of the steel plate, and the steel plate itself is non-combustible. However, due to the need for heat insulation and sound insulation, many buildings use sandwich color steel plates, and its flammable substances are hidden in the core material of the sandwich color steel plates.
Selection method of color steel plate
First, observe the thickness of the substrate and the thickness of the film
The color steel plate is composed of a substrate and a colored peritoneum or plating. We must first consider the thickness of the substrate and the peritoneal coating. The better color steel substrate is 0.02 ~ 0.05mm, and the thickness of the film or coating is often less than 0.15mm. Because from the perspective of affecting the use time of the color steel plate, the thickness of the substrate is very important. And some manufacturers of color steel plates often work 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 color steel plates, which greatly reduces the use of color steel plates Life is over.
Second, observe the leakage edge of the color steel plate
When I got a color steel plate, I first observed whether the exposed steel such as the cross section of the color steel plate was finely crystallized, and whether it was gray, dark, or foreign. If the cut surface is crystalline and fine, the quality is superior.
Third, listen to the sound
Use your fingers or a hard object to strike the color steel plate. If the material of the color steel plate is poor, the sound emitted is dull, the metal sound is not obvious, and the metal sound of the better color steel plate is relatively loud and crisp.
Fourth, check the quality certificate of color steel plate
Whether there are inspection standards of relevant departments. If possible, go to the manufacturer of the color steel plate for site inspection. See how the business environment is and whether it is formal. Ask about the word of mouth of this company in the market.
Five, look at the price
Anything is a penny. When we compare the quality of color steel plates, the price is one aspect, but do not pay too much attention to the price. If the price of one color steel plate is much lower than others, then we must pay attention.
