How to distinguish the quality of color steel plate
Color steel plate refers to color coated steel plate, with organic coating. Color steel plates are
divided into single board, color steel composite board, floor board and so on. Widely used in large
public buildings, public buildings, mobile panels, and walls and roofs of integrated houses.
1. Observe the thickness of the substrate and the thickness of the film
The color steel plate is composed of a substrate and a colored peritoneal or plated layer. We must
first consider the thickness of the substrate and peritoneal coating. The better color steel plate
substrate is 0.02~0.05mm, and the thickness of the coating or coating is usually only 0.15mm. The
thickness of the substrate is important because it affects the use time of the color steel plate. Some
manufacturers of color steel plates often use hands and feet on the substrate and color steel coating or
coating. 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 use of color steel plates

2. Observe the outer leakage edge of the color steel plate
First, observe whether the exposed steel of the color steel plate, such as the section, is crystallized,
whether it is ash, dark, and impurities. If the cut surface is crystalline and fine, the quality is superior.
3. Check how does it sound
If you use a finger or a hard object to strike the color steel plate, if the material of the color steel
plate is poor, the sound emitted is boring, the metal sound is not obvious, and the metal color sound
of the better color steel plate is louder and crisper.
4. View the quality certificate of color steel plate
Is there a test standard for the relevant department? If possible, try to go to the manufacturer of
the color steel plate for field visits. Look at the environment of the company, whether it is formal.
Inquire about the reputation of this company in the market.
Anything is a penny. When we compare the quality of color steel plates, the price is one side, but
don't pay too much attention to the price. If the price of a color steel plate is much lower than the
others, then we have to pay attention.
