Mechanical Properties
Tensile Strength
Our Unbeatable Tin Roofing Sheets deliver exceptional tensile strength (≥230 MPa for Tinplate; ≥350 MPa for Al-Zn Steel), ensuring resistance to deformation under extreme loads such as heavy snow (up to 150 psf) and wind speeds exceeding 150 mph. This makes them ideal for coastal and seismic-prone regions.
Bend Strength
The unique HRB80 hardness ensures superior bend strength (≥180 MPa), preventing cracking during installation or thermal expansion. Rigorous cyclic load testing confirms zero fatigue failure after 10,000+ cycles.
Identification & Traceability
Each sheet is laser-etched with traceable identifiers:
- Material Grade (e.g., ETP, Al-Zn)
- Batch Number (Linked to mill certificates for full traceability)
- Coating Type (Tin/Stone/Cap Sheet Roofing Lamination)
- Fire Resistance Rating (Class A1 Non-Combustible)
Weight Calculation Formula
For quick estimates, use:
Weight (kg/m²) = Thickness (mm) × 7.85 × (1 + Coating Factor)
Example: A 0.5mm Al-Zn sheet with stone coating (Coating Factor 0.15):
Weight ≈ 0.5 × 7.85 × 1.15 = 4.51 kg/m².

Why Tin Roofing Sheets Resist Corrosion?
While tin and Al-Zn coatings are inherently corrosion-resistant, improper handling or environmental factors can cause localized damage:
- Galvanic Corrosion: Direct contact with copper or carbon steel in humid environments accelerates oxidation. Use dielectric isolators during installation.
- Chloride Exposure: Coastal salt spray degrades tin coatings; upgrade to cap sheet roofing lamination for marine applications.
- Mechanical Abrasion: Hail or debris scratches the surface. Our stone-coated sheets include a sacrificial layer to absorb impact.
- Acidic Rain: pH <5.0 erodes tin coatings. Electrolytic tin’s cathodic protection (E° = -0.14V) slows iron dissolution, extending lifespan to 30+ years.
Key Advantages
- Weatherproof Design: Withstands UV radiation, hail (up to 50mm diameter), and wind uplift forces exceeding 90 psf.
- Energy Efficiency: Reflective stone coatings reduce attic temperatures by 15°C, cutting cooling costs by 20%.
- Aesthetic Flexibility: Available in 12+ colors and textures, compatible with modern and traditional architectures.
