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 first have to consider the thickness of the substrate and peritoneal coating, the better color steel plate substrate is 0.02~0.05mm, the film or coating thickness is often only 0.15mm. Because from the point of view of the use of color steel plate, the thickness of the substrate is very important. And some production of color steel plate manufacturers often in the substrate and color steel plate coating or film on the hands and feet, they reduce the thickness of the substrate, but increase the thickness of the peritoneal membrane to reduce the production cost of color steel plate, which greatly reduces the service life of the color steel plate

2: observe the leakage edge of the color steel plate
When I got a color steel plate, I first observed whether the exposed steel of the color steel plate, such as the cross section, is crystalline and dense, and whether it is gray, dark and impurity. If the cut surface is of fine crystalline type, the quality is superior.
3: Listen to the sound
Use fingers or hard objects to hit the color steel plate, color steel plate material if poor, then the sound is dull, the metal sound is not obvious, the material is better color steel plate metal sound is more loud, crisp.
4: Check the quality certificate of color steel plate
Whether there are inspection standards of relevant departments. If possible, try to go to the manufacturer of color steel plate for on-the-spot investigation. Look at the business environment, whether formal. What is the reputation of this enterprise in the market.
5: Look at the price
Everything is a penny. When we compare the quality of color steel plates, the price is on the one hand, but don't pay too much attention to the price. If the price of a color steel plate is much lower than the others, then we should pay attention to it.
