Color steel sandwich panels are also a necessity in construction. Many people do not know how to buy color steel sandwich panels. Next, Xiaobian will teach you how to distinguish the quality of color steel sandwich panels.
1. Observe the leakage edge of color steel sandwich panel
After getting a sandwich plate, I first observed whether the exposed steel of the color steel plate, such as the section, was crystallized and dense, and whether it was gray, dark and impurities. If the cut surface is fine crystalline, the quality is superior.
2. Listen to the sound
Knock the color steel plate with fingers or hard objects. If the color steel plate is poor in material, the sound will be dull, and the metal sound is not obvious. The metal sound of the color steel plate with good material is loud and clear.
3. Observe the thickness of substrate and coating
The color steel sandwich plate is composed of a base plate and a color peritoneum or plating. First of all, we have to consider the thickness of the substrate and the coating. The better color steel substrate is 0.02-0.05m (Shanwei color steel sandwich panel manufacturer m), and the thickness of the coating or coating is often only less than 0.15mm.
4. Check the quality certificate of color steel sandwich panel
Whether there are inspection standards of relevant departments. If possible, go to the manufacturer of sandwich panel for field investigation. See how the environment of the enterprise is and whether it is formal. Ask about the reputation of this enterprise in the market.
