Mechanical Properties
Tensile Strength
Our metal sheets for roof deliver exceptional tensile strength (≥230 MPa for Tinplate; ≥350 MPa for Al-Zn Steel), ensuring resistance to deformation under heavy snow loads, wind pressures up to 150 mph, and seismic activity. This makes them ideal for regions prone to extreme weather, such as coastal areas and mountainous terrains.
Bend Strength
The unique stone-coated or laminated plastic roof sheets design enhances bend strength (≥180 MPa), reducing cracking during installation or thermal expansion. Rigorous testing confirms zero fatigue failure after 10,000+ cyclic load cycles.
Identification & Traceability
Each sheet is laser-etched with:
- Material Grade (e.g., ETP, Al-Zn)
- Coating Type (Tin/Stone/Plastic)
- Batch Number (Traceable to mill certificates)
- Fire Resistance Rating (Class A1 Non-Combustible)
This ensures compliance with global construction codes and simplifies quality audits.
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 plastic roof sheets 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%.
- Eco-Friendly: 100% recyclable materials align with LEED certification requirements.
