How to judge the quality of colored coated steel Coil in PPGI/PPGL Coil

PPGI/PPGL Coil There are many new building materials available for the current building materials market, but the variety of colored coated rolls is increasingly becoming a popular choice. The important thing is that it can meet people's needs in all aspects. As people have higher and higher requirements for building materials, people should pay attention to quality issues when buying building materials, so how to judge the quality of building materials is very important.

Shejin steel is an honest and professional steel supplier in China;

Observe the thickness of the substrate and coating on the color coated steel coil: the color plate consists of the substrate, color peritoneum or coating. We need to consider the thickness of the substrate and peritoneal coating. A good steel substrate ranges from 0.02mm to 0.05mm, with a coating or coating thickness usually less than 0.15mm. The thickness of the substrate has a very important effect on the use time of the color plate. Color steel plate on some substrates is usually compounded or laminated with color steel plate to reduce the thickness of the substrate, but increase the thickness of the peritoneum to reduce the production cost of color steel plate and greatly reduce the service life of color steel plate.

Observe the edge leakage of color steel plate: when taking color steel plate, observe the exposed steel plate, such as section, whether there are small, gray, black and impurity crystals. If the cutting surface is crystal clear, the quality will be better.

Listen: Tap the colored steel plate with your finger or something nice. Color steel plate quality is poor, the sound is dull, the metal sound is not obvious. Colored steel sheet metal sounds loud and clear.

To sum up, color coated coil is a new type of building material, with good environmental protection function, widely used in roofs, walls, temporary houses and so on.
