For the current construction market, there are many new 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. Due to the increasing demand for building materials, people should pay attention to quality issues when purchasing building materials. Therefore, it is very important to determine the quality of building materials.

Observation of the thickness of the substrate and coating on the color coated roll: The color plate is composed of the substrate and the coating. We need to consider the thickness of the substrate and peritoneal coating. A better range of steel substrates is 0.02 mm to 0.05 mm, with coatings or coating thicknesses typically less than 0.15 mm. The thickness of the substrate has a significant impact on the lifespan of the color palette. Some color steel plates on substrates are usually composite or laminated with color steel plates to reduce the thickness of the substrate, but the thickness of the peritoneum increases to reduce the production cost of color steel plates and greatly reduce their service life. Board.

Observe the leakage of the color steel plate: When taking the color steel plate, observe the exposed steel plate, such as the cross-section, for any fine, gray, black, or impurity crystals. If the cutting surface is crystal clear, the quality will be better.

Listen: Tap the colored steel plate with your fingers or something good. The color steel plate material is poor, the sound is dull, the metal sound is not obvious, and the color steel plate metal sound is loud and clear.

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