Lightweight Tin Roofing Sheets | Easy Handling & Installation

Lightweight Tin Roofing Sheets | Easy Handling & Installation

Product Specifications

Key Features & Benefits

1. Superior Strength & Flexibility

   • Tensile Strength: Engineered with Grade DX51D steel cores, our sheets of tin roofing withstand tensile forces up to 800 MPa, resisting wind speeds of 180 mph and snow loads up to 50 psf. The trapezoidal corrugation pattern enhances rigidity, achieving bending strengths of 320–480 MPa, even under prolonged stress.
   • Lightweight Design: At 3.5–6.0 kg/m², these sheets reduce roof load by 60% compared to concrete tiles, making them ideal for retrofitting older structures.

2. Corrosion Resistance

   • The 40g/m² zinc-aluminum coating provides 4x longer rust protection than standard galvanized sheets. Zinc sacrificially corrodes before the steel substrate, forming a self-healing layer of zinc carbonate (Zn₅(CO₃)₂(OH)₆).
   • A secondary stone-chip finish shields against saltwater, acid rain, and abrasion, ensuring decades of rust-free performance.

3. Easy Installation

   • Pre-drilled holes and interlocking edges simplify DIY installation. Use roofing sheeting screws (hex-head with EPDM washers) to prevent water ingress.

4. Aesthetic Versatility

   • Available in 15+ colors (e.g., Slate Gray, Terracotta) and textures (Woodgrain, Sandstone) to complement modern or rustic architecture.

Technical Insights

Identification & Traceability

• Laser Marking: Each sheet features a laser-etched code (e.g., ZN40-DX51D) compliant with ASTM E384 and ISO 9001 standards for batch tracking.
• XRF Testing: X-ray fluorescence analysis verifies zinc coating density (40g/m² ±5%) and alloy composition (0.15% C, 0.6% Si).

Weight Calculation Formula

$$\text{Weight (kg)}=\text{Thickness (mm)}\times \text{Width (m)}\times \text{Length (m)}\times 7.85(\text{steel density})$$

Example: A 0.6 mm × 1.2 m × 2.4 m sheet weighs $0.6\times 1.2\times 2.4\times 7.85=13.6\text{kg}$.

Why Stainless Steel May Corrode
Despite its resilience, stainless steel can corrode under specific conditions:

• Chloride Exposure: Coastal saltwater or de-icing agents degrade the chromium oxide layer, causing pitting.
• Mechanical Scratches: Abrasions during installation expose the iron substrate to oxidation.
• Low Oxygen Environments: Stagnant water inhibits chromium oxide layer regeneration.
