In the application of color steel sandwich panels, our purchasers are very concerned about product quality, but they do not know how to distinguish. Now Jinan color steel sandwich panels factory will summarize the characteristics of high quality color steel sandwich panels. I hope you can understand in the future procurement process!
1. When we look at the color steel sandwich panel, the first thing we should pay attention to is the leakage edge. Usually, the color steel sandwich board with good quality has very fine crystalline edge, and there are no impurities such as blackening and graying.
2. Use our fingers to lightly tap the surface of the color steel sandwich panel and listen to the sound to judge the quality. If the quality of sandwich board is poor, the sound is very dull, and the sandwich board with superior quality can be magic crisp sound.
3. The basement film and coating of color steel sandwich board are also a concern. The basement film thickness of color steel sandwich board with good quality is usually kept between 0.02 mm and 0.05 mm, while the coating is controlled below 0.15 mm.
4. This is also very critical, that is to see the certification of the color steel sandwich panel we have chosen. Whatever commodity we choose, this is very important. If you have the opportunity, you can go directly to the manufacturer of the color steel sandwich panel to inspect, to ensure that the enterprise is regular, and the working environment is excellent, and no matter how bad it is, you should also inquire about the reputation of the brand.
