CorrosionGuard Tin Roofing Sheets | Zinc-Coated Excellence

Product Overview

Engineered for extreme durability and corrosion resistance, CorrosionGuard Tin Roofing Sheets are the ultimate solution for commercial, industrial, and residential roofing. Combining zinc-coated steel with advanced anti-rust technology, these aluminum roofing sheets outperform traditional materials in harsh climates, coastal zones, and chemically aggressive environments. Designed to meet ASTM A792 and ISO 9001 standards, they offer unmatched longevity and structural integrity.

Technical Specifications

Surface Finish Corrugated, Stone, Matte, Bright Silver, Anti-Fingerprint (AFP)
Coating Dual-layer zinc coating (30–275 g/m²) with chromate passivation
Temper T1-T5, DR7-DR9 (optimized for heavy loads)
Certifications ASTM A792, SGS, ISO 9001, EN 10143

Performance Characteristics

1. Tensile & Bend Strength

Our corrugated galvanised roofing sheets achieve tensile strengths of 260–620 MPa through precision cold-rolling and annealing processes. This ensures resistance to wind uplift (up to 180 mph) and structural deformation. Bend strength is validated at 180° without cracking, even in sub-zero temperatures (-40°C), making them ideal for regions with heavy snowfall or thermal cycling.

 

2. Weight Calculation

  • Formula: Weight (kg/m²) = Thickness (mm) × 7.85 (steel density)
  • Example: A 0.5 mm sheet weighs 3.925 kg/m², 50% lighter than traditional cheap steel roofing sheets while maintaining superior load-bearing capacity.

3. Corrosion Resistance Mechanism

The zinc-aluminum coating acts as a sacrificial anode, where zinc oxidizes preferentially to protect the steel substrate. In coastal or acidic environments, the outer zinc layer resists pitting, while the aluminum-rich inner layer forms a stable oxide barrier. This dual-action defense ensures a lifespan exceeding 50 years, even in chloride-rich atmospheres.


 

4. Why Stainless Steel Can Rust?

  • Electrochemical Corrosion: Foreign particles (e.g., iron dust) create micro-cells with moisture, accelerating oxidation.
  • Organic Acids: Residual pollutants or organic matter (e.g., food, algae) form corrosive acids over time.
  • Mechanical Damage: Scratches or abrasions expose the steel substrate, disrupting the protective oxide layer.
  • High-Temperature Degradation: Prolonged exposure to >120°C can destabilize the chromium oxide film in stainless steel.

Key Features

  1. Weatherproof Design: Withstands -40°C to +150°C, UV radiation, and salt spray (ASTM B117).
  2. Eco-Friendly: 100% recyclable with GalvaTec™ coating, reducing carbon footprint by 40% compared to aluminum roofing sheets.
  3. Easy Installation: Pre-punched holes and corrugated interlocking edges reduce labor costs by 30%.
  4. Low Maintenance: Self-cleaning surface prevents dirt accumulation and microbial growth.

Applications

  • Industrial: Chemical plants, coastal infrastructure, solar farms.
  • Commercial: Warehouses, airports, agricultural sheds.
  • Residential: Eco-homes, garages, patio covers.

Why Choose CorrosionGuard?

  1. Superior Anti-Corrosion: Dual-layer zinc-aluminum coating outperforms standard corrugated galvanised roofing sheets in saltwater environments.
  2. Cost Efficiency: Save 50% on lifecycle costs compared to cheap steel roofing sheets and asphalt shingles.
  3. Certified Durability: ASTM and ISO certifications ensure compliance with global construction standards.
  4. Local Availability: Fast delivery via nationwide distributors—search for "corrugated galvanised roofing sheets near me" for instant access.
  5. Aesthetic Flexibility: Choose from 15+ colors and textures to match architectural styles.

Why Our Stainless Steel Roofing Stands Out

  1. Dual-Layer Protection: Zinc coating + chromate passivation ensures 3x longer rust resistance than standard galvanized sheets.
  2. 50-Year Warranty: Backed by a limited lifetime warranty against perforation and color fading.
  3. Sustainable Manufacturing: Energy-efficient production with 80% recycled materials.
  4. Global Compliance: Meets ASTM, EN, and SANS standards for hazardous area installations.
