Color steel plate refers to color coated steel plate, which is a steel plate with organic coating. Color steel plate is divided into single board, color steel composite board, floor bearing board and so on. Widely used in the walls and roofs of large public buildings, public workshops, mobile homes, and integrated houses.
1：Observe substrate thickness and film thickness
The color steel plate is composed of a substrate and colored peritoneum or plating. 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 from the point of view of affecting the use time of the color steel plate, the thickness of the substrate is very important. Some manufacturers of color steel plates often make hands and feet on the substrate and 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 color steel plates. Longevity.
2：Observe the leaking edge of the color steel plate
After getting a color steel plate, I first observe whether the exposed steel of the color steel plate, such as the cross-section, is finely crystallized, whether it is gray, dark or foreign. If the cut surface is of fine crystal type, the quality is relatively superior.
3：Listen to the sound
Use a finger or a hard object to hit the color steel plate. If the material of the color steel plate is poor, the sound is boring, 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 color steel plate
Whether there are inspection standards of relevant departments. If possible, go to the site of the color steel plate manufacturer as much as possible. Look at the company's environment and whether it is formal. Ask about the reputation of this company in the market.
5：See price
Anything is a penny and a penny. When we compare the quality of color steel plates, the price is one thing, but don't 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.
