As the enclosure system of Shanxi steel structure building, color steel plate is often used in engineering, especially in the construction of Shanxi steel structure plant, the roof and wall of the plant can not be separated from color steel plate or color
steel sandwich plate. When we buy color steel plates, we are often not assured of their quality. Sometimes we buy a thicker type of plate, and the bad merchants often make inferior ones, such as 0.48 thick plate as 0.52 plate. How can we judge these
problems? Now I will teach you several methods.
1. See thickness
In terms of the thickness, we mainly look at the thickness of the substrate and the thickness of the peritoneum. Because color steel plate is made of base plate and color coating, we should first consider whether the thickness of
base plate meets the standard. The better substrate thickness is between 0.02 and 0.05mm, and the coating is usually less than 0.15mm. If the thickness of the substrate becomes thinner, it will inevitably affect the service life of the color steel plate,
and corrosion will occur in a long time.
2. Look at the edge
First of all, we can take a sample to observe whether the exposed steel of color steel plate, such as cross section, is crystallized and dense, and whether there is gray and dark
phenomenon. If its cross section is crystal fine, then the quality is better.
3. Listen to the voice
After observing its edge, we can tap the color steel plate with fingers or other hard objects. If the color steel plate is of poor quality,
the sound will be dull. If the sound is loud and clear, then it can prove the quality of the plate.
4. See certificate
We can check whether this kind of color steel coil has the inspection standards and certificates of relevant departments.
If we are going to purchase a large number of color steel plates, we can go to the manufacturer for field inspection to see the production environment of the enterprise and see the production scale and reputation of the enterprise.
5. Look at the
As the saying goes, when we buy color steel plates, the price is also a factor we need to consider, but we can't pay too much attention to the price. If the price is too low, then we need to pay attention.
