How to judge the difference between the quality of color coated roll

For the current construction market, there are many new types of building materials, but the diversity of color coated rolls has gradually become a popular choice. The important thing is that it can meet people's needs in all aspects. As people's requirements for building materials are getting higher and higher, people should pay attention to quality issues when buying building materials, so how to judge the quality of building materials is very important.

Color coating roll observation substrate and coating thickness: color plate by the substrate and color peritoneal or coating composition. We need to consider the thickness of the substrate and the peritoneal coating. More preferred steel substrates range from 0.02mm to 0.05mm, and the coating or coating thickness is typically less than 0.15mm. The thickness of the substrate has a very important influence on the use time of the color plate. The color steel plate on some substrates is usually laminated or laminated with the color steel plate to reduce the thickness of the substrate, but the thickness of the peritoneum is increased to reduce the production cost of the color steel plate and greatly reduce the service life of the color steel plate. Board.

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

Listen: Use your fingers or good things to knock on the color steel plate. The color steel plate material is bad, the sound is dull, the metal sound is not obvious, the color steel plate metal sound is loud and clear.

In summary, the color coating roll is a new type of building material with good environmental protection functions and is widely used in roofing, walls, temporary houses, etc.
