Seamless Tin Roofing Sheets | Precision Fit & Finish

Product Overview

Engineered for unparalleled durability and aesthetic versatility, our roofing tin sheets redefine modern roofing solutions. Crafted from premium-grade tinplate (SPTE) and zinc-aluminum alloys, these seamless sheets combine corrosion resistance, structural integrity, and precision engineering. Ideal for residential, commercial, and industrial applications, they outperform traditional pvc roofing sheet alternatives in harsh climates while maintaining competitive roof metal sheet price advantages.

Technical Specifications

Attribute Details
Material Tinplate (SPTE) / Galvalume® (55% Al, 43.4% Zn, 1.6% Si)
Hardness TS230–TS620 (adjustable for seismic or high-wind regions)
Thickness 0.14–0.6 mm (customizable to 0.18 mm for lightweight designs)
Width 600–1250 mm (seamless overlap for leak-proof installation)
Surface Finish Corrugated, Matte, Stone, Anti-Fingerprint (AFP), Custom Embossing
Coating Dual-layer zinc-aluminum (30–275 g/m²) with chromate passivation
Temper T1-T5, DR7-DR9 (optimized for load-bearing up to 150 kg/m²)
Certifications ASTM A623, ISO 9001, SGS, EN 10143

Performance Characteristics

1. Tensile & Bend Strength

Our roofing tin sheets achieve tensile strengths of 260–620 MPa through cold-rolling and annealing processes, validated by ASTM A789 standards. This ensures resistance to wind uplift (180 mph) and structural deformation. Bend strength is tested at 180° without cracking, even at -40°C, making them suitable for Arctic or alpine environments.

 

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 pvc roofing sheet alternatives while offering 3x higher load capacity.

3. Corrosion Resistance Mechanism

The zinc-aluminum coating acts as a sacrificial anode, where zinc oxidizes preferentially to protect the steel core. In coastal zones (chloride-rich environments), the aluminum-rich inner layer forms a stable oxide barrier, preventing rust diffusion. This dual-layer defense ensures a 50+ year lifespan, even under prolonged UV exposure.

 

4. Why Stainless Steel Can Rust?

  • Electrochemical Corrosion: Iron dust or salt deposits create micro-galvanic cells with moisture, accelerating localized pitting.
  • Organic Acid Exposure: Pollutants or organic residues (e.g., algae) generate corrosive acids that degrade protective layers over time.
  • Mechanical Damage: Scratches during installation expose the substrate, compromising the oxide film’s integrity.
  • High-Temperature Degradation: Prolonged exposure to >120°C destabilizes chromium oxide films in stainless steel, leading to scaling.

Key Features

  1. Weatherproof Design: Withstands -40°C to +150°C, UV radiation (ASTM G154), and salt spray (ASTM B117).
  2. Cost Efficiency: Competitive roof metal sheet price with 40% lower lifecycle costs vs. asphalt or pvc roofing sheet.
  3. Eco-Friendly: 100% recyclable with GalvaTec™ coating, reducing carbon footprint by 30%.
  4. Easy Installation: Pre-punched holes and interlocking edges cut labor time by 50%.

Applications

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

Why Choose Our Stainless Steel Roofing Sheets?

  1. Advanced Anti-Corrosion Tech: Dual-layer zinc-aluminum coating provides 3x longer rust resistance than standard galvanized sheets.
  2. Certified Durability: ASTM and ISO certifications ensure compliance with global construction standards.
  3. Sustainable Manufacturing: 80% recycled materials and energy-efficient production processes.
  4. Local Availability: Fast delivery via certified distributors—search for "roofing tin sheets near me" for instant access.
  5. 50-Year Warranty: Limited lifetime coverage against perforation and color fading.

Why Our Stainless Steel Stands Out

  • Precision Engineering: Laser-cut edges and uniform coating thickness ensure leak-proof performance, even in monsoon climates.
  • Global Compliance: Meets EU tariff regulations (HS codes 72101280, 72109040), ensuring seamless international shipments.
  • Aesthetic Flexibility: 15+ colors and textures to match architectural styles, from rustic to ultra-modern.
  • Proven Track Record: Trusted by 10,000+ installations worldwide, including Alphamin’s Bisie Mine infrastructure.
