Rust-Proof Tin Roofing Sheets | Ideal for Harsh Climates

Product Overview

Our metal sheets for roofing are engineered to withstand extreme weather conditions, from coastal salt spray to heavy snowfall. Made from premium-grade electrolytic tinplate (ETP) and tin-free steel (TFS), these roof metal sheets combine corrosion resistance, durability, and aesthetic versatility. Ideal for residential, commercial, and industrial applications, they are the ultimate solution for long-term roofing needs.

Performance Characteristics

1. Tensile & Bend Strength

Our roofing sheet metal undergoes rigorous cold-rolling and annealing processes to achieve tensile strengths of 260–620 MPa, ensuring resistance to wind uplift and structural deformation. The bend strength is optimized to withstand angles up to 180° without cracking, even in sub-zero temperatures.

 

2. Weight Calculation

  • Formula: Weight (kg/m²) = Thickness (mm) × 7.85 (steel density)
  • Example: For a 0.5 mm sheet, weight = 0.5 × 7.85 = 3.925 kg/m² (lighter than asphalt shingles by 50%).

3. Corrosion Resistance Mechanism

The tin/chromium layer forms a sacrificial anode, where tin oxidizes preferentially to protect the steel substrate. In acidic environments (e.g., coastal areas), the outer tin layer resists pitting, while the inner chromium oxide layer prevents rust diffusion.

 

4. Why Stainless Steel Can Rust?

  • Electrochemical Corrosion: Foreign particles (e.g., iron dust) create micro-cells with moisture, accelerating oxidation.
  • Organic Acids: Food residues or pollutants form corrosive organic acids over time.
  • Chemical Exposure: Direct contact with salts, alkalis, or industrial pollutants degrades protective layers.

Key Features

  1. Weatherproof Design: Withstands UV radiation, hail, and temperature fluctuations (-40°C to +120°C).
  2. Easy Installation: Pre-punched holes and interlocking edges reduce labor costs by 30%.
  3. Low Maintenance: Self-cleaning surface prevents algae and dirt accumulation.
  4. Eco-Friendly: 100% recyclable with GalvaTec™ coating to minimize environmental impact.

Applications

  • Residential: Ideal for sloped roofs, garages, and porches.
  • Commercial: Used in warehouses, airports, and solar panel mounting systems.
  • Industrial: Suitable for chemical plants and coastal infrastructure.
