Performance Attributes
Tensile Strength
The roofing with metal sheets series achieves tensile strengths up to 620 MPa (stainless steel) and 290 MPa (aluminium), ensuring structural resilience against wind loads up to 150 mph. Electrolytic tin plates exhibit a balanced strength-to-weight ratio, ideal for seismic and typhoon-prone regions .
Bendability
Precision-rolled edges and controlled tempering enable bending radii as low as 1.5× thickness without cracking. This is critical for forming complex roof geometries, such as arched or corrugated profiles .
Weight Calculation
- Aluminium: 2.7 g/cm³ (e.g., 0.5 mm sheet = 1.35 kg/m²)
- Copper: 8.96 g/cm³ (e.g., 0.6 mm sheet = 5.38 kg/m²)
- Tin Plate: 7.85 g/cm³ (e.g., 0.3 mm sheet = 2.36 kg/m²)
Lightweight designs reduce structural support costs by up to 30% compared to concrete tiles .
Anti-Corrosion Mechanism
Stainless steel’s chromium oxide layer (≥10.5% Cr) provides passive protection against oxidation. Aluminium roofing sheet leverages natural Al₂O₃ formation, while copper roofing sheets develop a patina (CuCO₃·Cu(OH)₂) for long-term durability. Electrolytic tin plates use sacrificial tin coatings to block moisture ingress .
Identification System
- Grade Marking: Laser-etched codes (e.g., SPTE-T3BA for tin plate, AA3003-H44 for aluminium).
- Color Coding: Edge stripes indicate thickness and alloy type.
- Batch Tracking: QR codes link to mill certificates and compliance reports .
Manufacturing Excellence
Process Flow
- Material Selection: Prime-grade coils sourced from ISO-certified mills.
- Surface Treatment:
- Tin plates: Electroplating → Acrylic resin coating → Stone granule bonding .
- Aluminium: PVDF/polyester coating → Clear anodization for UV resistance .
- Roll Forming: 26-stage hydraulic presses create uniform corrugations (e.g., 828 arc profile) .
- Quality Control: Eddy-current testing for coating uniformity; salt-spray tests exceed 1000 hours.
Customization Options
- Profiles: Trapezoidal, IBR, glazed tile, double-layer designs.
- Colors: 200+ RAL shades with 20-year fade warranty.
- Pre-Printed Designs: Lithographic patterns for branding (e.g., food can logos) .
Why Choose Our Stainless Steel Roofing Sheets?
- Unmatched Durability: Chromium-nickel alloys (304/316) resist pitting in chloride-rich environments, outperforming carbon steel by 5× lifespan .
- Fire & Wind Resistance: Class A fire rating (1630°C melting point) and UL 580 wind uplift certification .
- Sustainability: 100% recyclable with 60% recycled content; reduces HVAC loads via solar reflectance (SRI > 82) .
- Cost Efficiency: Lifecycle savings of 40% over asphalt shingles; minimal maintenance .
- Global Compliance: Meets EN 10202, ASTM A623, and Miami-Dade HVHZ hurricane codes .
