Overview
The Heavy-Duty Corrugated Metal Steel Roofing Sheet is a robust roofing solution engineered for high-performance in demanding environments. Featuring a classic corrugated profile, this sheet is made from galvanized or galvalume steel, offering superior resistance to heavy loads, extreme weather, and mechanical stress. The wave pattern design enhances structural integrity while improving water drainage and snow shedding.
Manufactured with precision roll-forming technology, the sheets are available in various thicknesses (0.3mm to 1.0mm) and coating weights (e.g., G90 galvanized), ensuring customization for different load requirements and climatic conditions. The pre-painted surface (in standard or custom colors) adds an extra layer of protection and aesthetic appeal.
Features
Enhanced Structural Strength: The corrugated design increases the sheet's moment of inertia, allowing it to span longer distances without additional support, reducing framework costs.
Excellent Water Management: Steep wave angles and deep troughs direct rainwater and melting snow efficiently, minimizing the risk of leaks and ponding.
Extreme Weather Resistance: Tested to withstand heavy snow (load capacity up to 300 kg/m²), hurricane-force winds (150 mph), and hailstones (up to 50mm diameter).
Low Maintenance: The galvanized coating inhibits rust, while the durable paint finish resists fading and chalking, requiring minimal upkeep over its lifespan.
Fire Retardancy: Steel is non-combustible, making these sheets a safe choice for areas prone to wildfires or industrial fire risks.
Application
Industrial Facilities: Perfect for factories, power plants, and warehouses that need long-lasting roofing capable of withstanding heavy machinery vibrations and airborne pollutants.
Commercial Buildings: Used in large retail centers, sports complexes, and logistics hubs, where wide-span roofing and quick installation are essential.
Agricultural Buildings: Provides reliable protection for grain storage facilities, dairy farms, and equipment sheds, resisting corrosion from animal waste and fertilizer exposure.
Infrastructure Projects: Suitable for airports, train stations, and stadiums, combining structural durability with modern architectural aesthetics.
FAQ
Q: Can corrugated sheets be installed over existing roofs?
A: Yes, they can be installed on top of old roofs (with proper structural assessment) to save time and disposal costs.
Q: How does the corrugation affect insulation?
A: The air gaps created by the corrugation can enhance thermal insulation when combined with appropriate insulation materials.
Q: What is the typical lifespan?
A: With proper installation and maintenance, these sheets can last 30-50 years, depending on the coating type and environmental exposure.
Q: Are they noisy during rain?
A: Adding an underlayment or insulation layer can significantly reduce noise transmission, making them suitable for residential applications as well.
