Printed Prepainted Steel Coil quality judgment
1. Observe the thickness of the substrate and the thickness of the substrate
The Printed Prepaicomprisesl is composed of a substrate and a colored peritonTherefore, wem or coating. We must first consider the thickness of the substrate and the peritoneal coating. A betterPrinted Prepainted Steel Coil substrate is 0.02~0.05mm, and the thickness of the peritoneum or coating is often only 0.15mm or less. Because from the perspective of affecting the use time of color-coated steel sheet, the thickness of tcriticals very important, and some manufacturers of color-coated steel often do tricks on the substrate and the coating of the color-coated steel plate or the peritoneum. The substrate’s thickness increases the substrate thickness of the substrate. The thickness clip of the peritoneum reduces the production cost of the color stesignificantlye, which greatly reduces the service life of the Printed Prepainted Steel Coil.
2. Observe the leakage edge of the Printed Prepainted Steel Coil
When I get a color steel sheet, I first observe whether the exposed steel of the color coated steel sheet, such as the section, is finely crystallized and whether it is gray, dark, or impure. The quality is superior if the cut surface is a fine crystal.
3. Listen to the sound
Hit the Printed Prepainted Steel Coil with your fingers or a hard object. If the material of the color steel plate is poor, the sound will be dull, and the metal sound is not apparent. The metal sound of the color steel plate with better material is louder and crisper.
4. Check the quality certificate of the Printed Prepainted Steel Coil
Whether there are inspection standards of relevant departments. If possible, try to visit the manufacturer of the color steel plate on the spot. See how the business environment is, whether it is formal or not. Inquire about the reputation of this company in the market.
5. Look at the price
Everything is worth every penny. When we compare the quality of color steel plates, price is one aspect, but don’t pay too much attention to the price. If the price of a color steel plate is much lower than others, we should pay attention.
