Zinc Roof Sheet

Zinc roof sheet, also known as galvanized roof sheet, is a material widely used in the construction field. The following is a detailed explanation of it:

1. Definition and characteristics

• Definition: Galvanized roof sheet, also known as galvanized corrugated iron roof, galvanized corrugated iron roof, is a metal sheet with a galvanized surface, usually used for roof covering.
• Corrosion resistance: Due to the stable chemical properties of zinc, the galvanized layer can effectively prevent the steel sheet from rusting and corrosion, extending the service life.
• Lightweight and high strength: The galvanized roof sheet is light in weight but high in strength, easy to carry and construct.
• Aesthetics: The surface of the galvanized steel sheet is smooth and has a metallic luster, which can enhance the overall aesthetics of the building.
• Economical: The galvanized roof sheet is moderately priced and easy to maintain and replace, reducing the construction cost.

2. Specifications and parameters

• Thickness: The thickness of the galvanized roof sheet is usually between 0.12mm and 0.8mm. Sheets of different thicknesses are suitable for different construction needs and load-bearing capacities.
• Width and length: The width and length of the sheet can be customized according to customer needs. The common width range is between 600mm and 1150mm, and the length can reach 1000mm to 11800mm.
• Zinc layer thickness: The zinc layer thickness is an important indicator to measure the corrosion resistance of galvanized roof panels, usually expressed in grams per square meter (GSM) or microns (μm). The common zinc layer thickness ranges from 30GSM to 275GSM.
