The main structure of clean rooms and modern workshops is actually color steel composite panels. Up to now, color steel composite panels are still an indispensable main material for building clean rooms or workshops. This requires that the fire rating of the color steel composite panel must be much higher than that of other materials. Poor quality color steel composite panel products, the price may look beautiful, but the hidden dangers are great. So how to distinguish the advantages and disadvantages of color steel plate? The quality of color steel plate is affected by many aspects, such as color coated steel plate, production process and equipment, operator skill level and so on. The quality of raw materials directly determines the quality of the final product.
1: Observe the thickness of the substrate and the thickness of the film
The color steel composite board is composed of a substrate and a colored film. We must first consider the thickness of the substrate and the color film. A better color steel composite board substrate is 0.02~0.05mm, and the thickness of the film is often only 0.15mm or less. Because from the In terms of affecting the use time of color steel composite panels, the thickness of the substrate is very important. And some manufacturers of color steel composite panels often play tricks on the substrate and the coating of color steel composite panels. They reduce the thickness of the substrate, but increase the thickness of the substrate. The thickness of the color film can reduce the production cost of the color steel composite panel, which greatly reduces the service life of the color steel composite panel.
2: Observe the leakage edge of the color steel composite panel
When I get a color steel composite panel, I first observe whether the exposed steel of the color steel composite panel, such as the section, is finely crystallized, whether it is gray, dark and impurities.
3: listen to the sound
Tap the color steel composite panel with your fingers or hard objects. If the material of the color steel composite panel is poor, the sound will be dull and the metal sound is not obvious. The metal sound of the color steel composite panel with better material is louder. ,crisp.
4: Check the quality certificate of the color steel composite panel
Whether there are inspection standards of relevant departments. If possible, try to visit the manufacturer of color steel composite panels on the spot. See how the environment of the enterprise is and whether it is formal. Inquire about the reputation of this enterprise in the market.
5: Look at the price
Everything is worth every penny. When we compare the quality of color steel composite panels, the price is one aspect, but we should not pay too much attention to the price. If the price of one color steel composite panel is much lower than others, then We are about to pay attention.
