Weather-Resistant Tin Roofing Sheets | UV-Protected Coating

Weather-Resistant Tin Roofing Sheets | UV-Protected Coating

Product Specifications

Key Features & Benefits

1. Superior Strength

   • Tensile Strength: Our tin roof sheets achieve a tensile strength of 550–850 MPa, capable of withstanding wind speeds up to 170 mph and snow loads of 40 psf. The stainless steel core (Grade 304/316) ensures structural stability in coastal or high-humidity regions.
   • Bending Resistance: Reinforced trapezoidal corrugations provide bending strength of 320–480 MPa, preventing warping even under prolonged stress. Ideal for base sheet roofing in industrial or agricultural settings.

2. Weatherproof Design

   • UV-Resistant Coating: A chromium oxide layer (12% Cr) combined with acrylic resin blocks 99% of UV radiation, preventing fading and thermal expansion.
   • Hydrophobic Surface: Micro-grooves channel water efficiently, reducing ice buildup by 60% compared to flat clear corrugated roofing sheets.

3. Lightweight & Easy Installation

   • Weighing only 3.5–6.2 kg/m², our sheets reduce roof load by 75% versus traditional concrete slabs. Pre-drilled holes and interlocking edges enable DIY installation in 4–6 hours.

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., WS-304-UV) compliant with ASTM E384 standards, ensuring batch traceability and quality control.
• XRF Testing: X-ray fluorescence analysis verifies alloy composition, aligning with ISO 9001 and SGS certifications.

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 0.8 mm × 1.2 m × 3 m sheet weighs $0.8\times 1.2\times 3\times 7.85=22.6\text{kg}$.

Why Stainless Steel May Corrode
While highly resistant, stainless steel can corrode under extreme conditions:

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

Why Choose Our Stainless Steel Roofing?

1. 30-Year Warranty: Backed by ISO 14001 and TUV testing, our tin roof sheets excel in extreme climates.
