What material is the color steel tile made of
The base material of color steel tile is made of cold-rolled steel plate and hot-dip galvanized steel plate.
The color steel tile is degreased, phosphatized, chromated, baked, and finally pressed at high temperature. The color steel tile is a corrugated plate made of double-sided spraying of thin steel plates, which can be directly laid on the roof as a roof tile; In addition, the mechanical performance of color steel plate is very good, and the installation and construction are more convenient; Single layer color steel tile is not used for home decoration. If it is used in residential places, color steel sandwich panel is required, which has better heat insulation and sound insulation effects.
Precautions for purchasing color steel plate: 1. Observe the exposed edge of color steel plate: when purchasing color steel plate, first observe whether the exposed part of color steel plate is well crystallized. If the color steel plate is gray and dark, it means that the color steel plate is poor in material. If the cross section is well crystallized, it means that the quality is good;
2. Observe the thickness of the base plate and the thickness of the coating: the color steel plate is mainly composed of the base plate and the color peritoneal layer. Therefore, the thickness of the base plate is closely related to the thickness of the coating. The thickness of the high-quality color steel plate is between 0.02 and 0.05 mm, and the thickness of the peritoneal layer is 0.15 mm, in case of carelessness. If the thickness is too thin, it is not recommended to buy it;
3. Listen to the sound: When you buy the color steel plate, you can also tap the color steel plate with your fingers or hard objects to listen to the sound carefully. The sound of ordinary color steel plate is very bright and crisp, while the sound of inferior color steel plate is quite dull.
