Even if the advantages of prepainted steel roofing sheet are good, it is also a defect. What are the advantages and disadvantages of corrugate color steel sheet? Today I will explain to you one by one.
1. Color-coated corrugated sheet has the lightest color, bright colors, convenient installation and operation, and has excellent decorative design practical effects.
2. The compressive strength of the color-coated corrugated sheet is high, and it can be used as a ceiling load-bearing board, and it has excellent bending resistance.
3. The prepainted steel roofing sheet has excellent fire safety characteristics, and the surface layer does not need any decorative design.
Due to the use of spray painting technology on the outside of the prepainted steel roofing sheet, it is very easy to fall over time, which is harmful to the appearance and beauty. Generally, maintenance must be carried out every 2 years, but it is not easy to jeopardize the actual effect of the application without maintenance.
The actual effect of sound insulation and noise reduction of coated corrugated steel sheet is relatively weak, and the resistance to wind resistance is also relatively weak. If you want to add the actual effect of high partition and wind and snow, you need thicker interlayer and baffle, which will cause The application cost is greatly increased.
Therefore, the prepainted steel roofing sheet is made by spray painting the surface of the thick steel plate, but after the coating is dropped, the interior is also very prone to corrosion.
