The color-coated board is light in weight, beautiful in appearance, good in corrosion resistance, and can be directly processed. It provides a new type of raw material for the construction industry, shipbuilding industry, automobile manufacturing industry, furniture industry, electrical industry, etc. It has played a very good role in replacing wood with steel, rapid construction, energy saving and pollution prevention.
1. Observe the thickness of the substrate and the thickness of the coating
Color-coated plates consist of a matrix and a colored peritoneum or coating. First, we have to consider the thickness of the stroma and peritoneal coating. The better substrate is 0.02~0.05mm, and the thickness of the film or coating is usually less than 0.15mm. Because the thickness of the substrate is very important from the perspective of affecting the service time of the color-coated board, some manufacturers of the color-coated board often tamper with The substrate and the color-coated board are coated or laminated to reduce the thickness of the substrate, but the thickness of the peritoneum is increased to reduce the production cost of the color-coated board, which greatly reduces the service life.
2. Observe the leakage edge
When you get a color-coated board, first observe whether the exposed steel of the color-coated board, such as the section, is finely crystallized, and whether it is gray, dark, or impurity. If the cut surface is a fine crystal, the quality is relatively superior.
3. Listen to the sound
Tap with your fingers or a hard object. If the material is poor, the sound will be dull, and the metal sound will not be obvious. The material is better and the sound is louder.
4. Check the quality certificate
Whether there are inspection standards of relevant departments. If possible, go to the factory to inspect the site to see if the company is formal.
5. Look at the price
Everything is worth every penny. When we compare the price of color-coated boards, the quality is one aspect, but don’t pay too much attention to the price. If the price of one color-coated board is much lower than the other, then we should pay attention.
