Features:
1. Light weight: 10-14 kg/square meter, equivalent to 1/30 of a brick wall.
2. Thermal conductivity: λ<=0.041w/mk.
3.High strength: It can be used as a ceiling panel for load-bearing, bending and compressive resistance; general houses do not use beams and columns.
4. Bright color: No surface decoration is required, and the anti-corrosion layer of the colored galvanized steel sheet will last for 10-15 years.
5.Flexible and fast installation: the construction period can be shortened by more than 40%.
6. Oxygen Index: (OI) 32.0 (Provincial Fire Products Quality Inspection Station).

Which type of sheet is best for roofing?
Advantages: Polycarbonate sheeting is an excellent option for roofs, owing to its properties - it is lightweight, highly durable, UV-resistant, fire-resistant and has low maintenance cost. Since they are pH-neutral, they can withstand contrasting temperatures while maintaining stability.

What is galvanized roofing sheet?
Traditional galvanized metal roofing is a corrugated carbon steel sheet with a galvanized coating.The coating is created by dipping the straight sheet in hot molten zinc. The zinc ions bond with iron molecules in the steel to create a shiny, rust-resistant surface finish. This process is called galvanization.

How long do galvanized roof sheets last?
Galvanized steel roofing can last 20 to 50 years if it is installed properly and with periodic maintenance. Galvanized steel roof panel is coated with zinc, which makes it more corrosion-resistant and durable.

What is the best thickness for a roofing sheet?
Thickness 0.35-0.40mm: Best for medium roofing and general walling projects such as small or medium-sized factories. Thickness 0.40-0.47 mm: Best for medium-to-large roofing projects such as medium-sized factories or buildings that require high-quality construction.
