Widely used in construction and industrial applications, it combines durability with cost-effectiveness.

Galvanized roofing sheet, also known as galvanized corrugated steel sheet, is a building material made from steel coils coated with a protective zinc layer through a hot-dip or elector-galvanizing process. Its distinctive wavy pattern enhances structural strength and rigidity while allowing for efficient water drainage. Widely used in construction and industrial applications, it combines durability with cost-effectiveness.

Specifications

l Thickness: Ranges from 0.3 mm to 1.5 mm, depending on application requirements.  

l Zinc Coating: Typically categorized by coating weight (e.g., Z60 to Z275, indicating 60–275 g/m² of zinc).  

l Corrugation Types: Common profiles include trapezoidal, sinusoidal, or ribbed patterns, with wave heights of 15–50 mm.  

l Dimensions: Standard widths range from 600 mm to 1,200 mm, while lengths are customizable (often up to 12 meters).  

Applications

l Roofing & Cladding: Used for residential, commercial, and industrial buildings due to weather resistance.  

l Fencing & Partitions: Provides secure and long-lasting barriers for agricultural or industrial sites.  

l Temporary Structures: Ideal for disaster relief shelters, construction sites, and storage facilities.  

l Agricultural Use: Employed in greenhouses, poultry sheds, and grain storage.  

l Infrastructure: Utilized in drainage systems, highway sound barriers, and railway projects.  

Key Advantages  

l Corrosion Resistance: Zinc coating protects against rust, extending lifespan to 20–50 years.  

l High Strength-to-Weight Ratio: Lightweight yet durable, reducing transportation and installation costs.  

l Low Maintenance: Resists UV rays, pests, and extreme weather, minimizing upkeep.
