Title Four Characteristics of PPGI corrugated roofing sheet
Description PPGI corrugated roofing sheet has the following four characteristics: 1. Fireproofing: The so-called fireproofing of PPGI corrugated roofing sheet for sale refers to two aspects a. As for the fire resistance of the coating, there is no corresponding standard in the current national standard, so other methods are used. Because the color plate has been cured at high temperature, the high-temperature resistance is better than self-drying. b. There are many factors affecting the fire resistance of the structure, such as the strength, thickness of the steel plate and the shape of the profiled plate. The strength of the steel plate is stipulated in the ASTM A792 standard as high-temperature steel (HTS), yield strength 275-380 MPa and tensile strength 360-460 MPa. 2. The corrosion resistance of PPGI corrugated roofing sheets. Generally, PPGI corrugated roofing panels for buildings have strong corrosion resistance and weatherability under the protection of both base plate coating and coating, which makes the life of ordinary paints more than ten times. Seismic resistance, because the color-coated steel plate has greater strength, lighter weight than brick-concrete structure, has strong seismic resistance. 3. The PPGI corrugated roofing sheet has good bending and rolling formability and good processability. 4. The color coated board has beautiful appearance, strong decoration, and observability.
