Product Description
The Corrugated Durable Aluminum Sheet Coil for Roofing represents a heavy-duty roofing solution engineered to deliver long-term weather resistance and structural reliability across diverse climates. Constructed from 3003 or 5052 aluminum alloys, these sheets feature a corrugated profile (7/8″ or 1-1/2″ pitch) that enhances load-bearing capacity while facilitating rapid water drainage. Their lightweight design and durable coatings make them a preferred choice for residential, commercial, and industrial roofing projects seeking low maintenance and extended service life.
Parameter | Value |
Alloy Type | 3003, 5052 |
Thickness | 0.5–3mm |
Salt Spray Resistance | ≥1,000 hours (ASTM B117) |
Surface Finish | PVDF coating (50–100μm thickness) |
Width | 600–1,200mm |
Extreme Weather Protection: PVDF (Kynar 500®) coating resists UV degradation, color fading, and chalking—maintaining 95% of initial gloss after 20 years of exposure, far exceeding acrylic-coated alternatives.
High Structural Integrity: The corrugated design increases bending strength by 30% compared to flat sheets, supporting snow loads up to 1.5kPa and wind speeds up to 120km/h without deformation.
Lightweight & Easy Installation: At 2.7g/cm³, these sheets reduce roof load by 50% compared to steel, enabling installation on lightweight frames with hidden fasteners that prevent water infiltration.
Fire Resistance: Aluminum’s inherent non-combustible properties meet ASTM E108 Class A fire ratings, critical for commercial buildings and wildfire-prone regions.
Residential Roofing: Ideal for coastal homes and hurricane zones, where saltwater resistance and wind durability reduce maintenance costs by 40% over asphalt shingles.
Commercial & Industrial: Warehouses, manufacturing facilities, and agricultural barns benefit from 50+ year service life and easy expansion with overlapping sheet designs.
Infrastructure Projects: Stadiums, transit stations, and water treatment plants use the sheets for their chemical resistance and ability to span large areas without intermediate supports.
Green Building: Contributes to LEED credits through recyclability (100% recyclable) and reflective coatings that reduce heat island effect by 2–3°C.
Q: Can the sheets be painted?
A: Yes, after light sanding to roughen the surface, they accept acrylic or epoxy paints for custom color matching. PVDF-reinforced paints are recommended for maximum durability.
Q: What is the recommended roof pitch?
A: A minimum pitch of 3:12 (14°) ensures proper drainage. For flat roofs (<2:12), sealant strips between panels and additional slope drains are required to prevent ponding.
