Analysis of color steel plate refers to color coated steel plate, which is a steel plate with organic coating. Color steel plates are divided into single plates, color steel composite plates, floor decks, etc. Now it has been widely used in the wall and roof of large public buildings, public factories, prefabricated houses, and integrated houses. In fact, rock wool board and color steel plate are similar products. Next, the editor will talk about the analysis of the quality of color steel plates.

　　 1. Investigate the thickness of the substrate and the film

　　 color steel plate is composed of substrate and colorful peritoneum or coating. We must first consider the thickness of the substrate and the peritoneal coating. A better color steel plate substrate is 0.02~0.05mm, and the thickness of the coating or coating is usually less than 0.15mm. Because from the perspective of the use time of the color steel plate, the editor believes that the thickness of the substrate is very important. Some manufacturers make changes to the substrate and the color steel plate coating or film. They reduce the thickness of the substrate, but increase the thickness of the peritoneum to reduce the production cost of the color steel plate, which greatly reduces the service life of the color steel plate.

　　 2. Investigate the leakage margin of the color steel plate

　　 After getting a color steel plate, the editor suggests that you first investigate whether the color steel plate reveals that the steel material such as the section is finely crystallized, whether it is gray, dark, and impurities. If the cut surface is crystalline and dense, the quality is better.

　　3, listen to the sound

　　 Hit the color steel plate with your fingers or with a hard object. If the material of the color steel plate is poor, the sound will be dull, and the metal sound is not obvious. The metal sound of the color steel plate with better material is relatively loud and loud.

　　4. Check the quality certificate of the color steel plate

　　Is there any relevant part of the inspection standards? If possible, try to visit the color steel plate manufacturer. See how the business environment is and whether it is formal. Ask in the market how the reputation of this company is.

　　 5. Look at the price

　　Everything gets what you pay for. When we compare the quality of color steel plates, price is one aspect, but don't pay too much attention to price. If the price of a color steel plate is much lower than others, then we must pay attention

The above is the analysis of the selection of the quality of the rock wool board summarized by the editor for everyone. It mainly depends on the investigation of the thickness of the substrate and the thickness of the coating, the leakage margin of the color steel plate, listening to the sound, and checking the quality certificate of the color steel plate. The price of these several methods, I hope to help everyone.
