Technical Properties
Tensile Strength
Our corrugated metal roofing sheets achieve tensile strengths between 270 MPa and 550 MPa, ensuring structural integrity under extreme weather conditions like heavy snow loads (up to 150 kg/m²) and wind speeds exceeding 150 km/h. The corrugated design enhances load distribution, reducing the risk of deformation and extending lifespan to 50+ years.
Bending Strength
Engineered with a trapezoidal profile, these sheets exhibit exceptional bending resistance, minimizing sagging over spans up to 1.2m. The cheap metal roofing sheets maintain bending strength above 350 MPa, validated by third-party testing under ASTM A653 standards.
Weight Calculation Formula
Calculate weight per square meter:
Weight (kg/m²) = (Thickness in mm × 7.85) + Zinc Coating Weight (g/m²) × 0.001
For example, a 0.4mm sheet with 40g/m² coating weighs 3.54 kg/m²—40% lighter than concrete roofing.
Identification & Marking
Each sheet is laser-etched with:
- Material Grade (e.g., DX51D+AZ)
- Zinc Coating Class (Z30/Z40)
- Batch Number for traceability
- Certification Marks (ISO, CE).
Why Galvanized Steel Resists Rust?
While polycarbonate roofing sheets and metal variants are corrosion-resistant, improper handling or environmental factors can cause localized rust. Key considerations include:
- Zinc Sacrificial Protection: The zinc layer oxidizes preferentially, shielding the base steel.
- Coating Uniformity: Electro-galvanizing ensures a consistent 30g/40g/m² zinc layer, preventing pinhole defects.
- Environmental Exposure: Coastal areas with salt spray require 40g/m² coatings for extended durability.
- Recyclability: Galvanized steel is 100% recyclable, reducing landfill waste.
Applications
- Residential Roofs: Lightweight corrugated metal roofing sheets reduce structural load while providing 50+ years of service.
- Commercial Warehouses: Withstand UV radiation and chemical exposure.
- Agricultural Sheds: Ventilated designs prevent condensation, protecting livestock and crops.
- Solar Panel Mounting: Compatible with rooftop solar installations using corrosion-resistant brackets.
Why Choose Our Eco-Friendly Roofing Sheets?
- Sustainable Materials: Made from recycled aluminum or galvanized steel with 50% recycled content in coatings.
- Energy Efficiency: Reflective surfaces reduce heat absorption by 75%, lowering cooling costs.
- Global Compliance: Meets ISO, CE, and LEED standards for eco-conscious construction.
- Cost-Effective: Cheap metal roofing sheets offer 2x the lifespan of asphalt shingles at 60% lower lifecycle costs.
- Customization: Tailored dimensions, profiles (e.g., trapezoidal waves), and pre-painted colors (RAL-based options).
