The color steel coil is made of hot-dip galvanized sheet, hot-dip galvanized sheet, electro-galvanized sheet, etc. as the substrate. The plate produced by the special color-coated coil factory has good durability, heat resistance, heat reflectivity, good welding performance and price ratio, and is an indispensable facility for industry and construction. Nowadays, in the market, although the quality of color-coated coils of most merchants has its certain guarantee, due to its huge demand, many merchants still focus on profit, and the quality of the products sold cannot be guaranteed. As the agent of many domestic steel plants and construction units of large steel structure projects, Sanxing can provide users with high-quality and reasonably-priced raw materials to escort the quality of the project.
There are currently four channels we can refer to when purchasing high-quality color steel coils;
1. Observe the thickness of the substrate and the thickness of the coating. Generally choose a thick sheet to extend its service life.
2. Listen to the sound; tap the color-coated coil with your finger or hard object, and the sound is dull, indicating that the material is poor, and the sound is relatively loud and crisp, indicating that the quality is good.
3. Observe the leakage edge of the coil; check whether the exposed steel and section are finely crystalline, gray, dark, and impurity. If the section is finely crystalline, the quality is also superior.
4. Look at the price; for any product, you get what you pay for.
