Tips for selecting color steel plates
1. Observation of substrate thickness and film thickness
The color steel plate is made of substrate and color peritoneum or electroplating.
First, the thickness of the substrate and peritoneum must be considered.
A relatively good color steel plate substrate is 0.02 to 0.05 mm, and the coating or coating thickness is usually less than or equal to 0.15 mm.
Because it will affect the use time of the color steel plate, the thickness of the substrate is very important.
2. Observe the leakage edge of the color steel plate
To obtain a color steel plate, first observe whether the crystals of the exposed steel cross-section of the color steel plate are dense and whether there are gray, dark and impurities. If the cut surface is a fine crystal type, the quality is good.
3. listen to the sound
Hit the color steel plate with your fingers or a hard object.
If the color steel plate is of poor quality, the sound will be blocked, and the metallic sound will not be obvious.
The metal sound of the color steel plate of good material will reverberate better and be transparent.
4. Display the quality certificate of color steel plate
Whether there are inspection standards of relevant departments.
If possible, please go to Nanli Qiang’s color steel plate manufacturing plant for on-site investigation as much as possible.
Let’s take a look at the environment of color steel plate manufacturers and whether it is formal.
In the market, listen to the reputation of this company.
5. Check the price
Everything is a commodity that pays for a penny.
When we compare the quality of color steel plates, the price is one aspect, but don’t pay too much attention to the price.
If the price of one color steel plate is very low for the other, we need to pay attention to several points.
