Innovative Tin Roofing Sheets | Lightweight & Fireproof
Product Overview
Our plastic roofing sheets redefine modern construction with unparalleled innovation, combining lightweight durability, fire resistance, and eco-friendly design. Engineered to meet ASTM DX51D and ISO 3575 standards, these sheet plastic roofing solutions are ideal for industrial, residential, and agricultural applications. Featuring a galvanized zinc-aluminum base and optional stone-coated finishes, they withstand extreme weather conditions while offering a 50+ year lifespan.

Key Attributes
1. Tensile & Bend Strength
Our plastic roofing sheets achieve tensile strength up to 500 MPa, validated through hydrostatic testing at 1.5× working pressure. The bend strength is optimized for wind loads up to 160 km/h, with corrugated profiles enhancing rigidity by 40% compared to flat sheets. These properties ensure resistance to deformation under snow loads (up to 1.5 kN/m²) and seismic stresses.
2. Identification & Marking
Each sheet is embossed with traceable identifiers:
- Material Grade (e.g., ASTM DX51D)
- Coating Type (Z275-Z600 for galvanized; AZ150 for Galvalume®)
- Batch Number (linked to mill certificates for quality assurance)
- Certification Marks (CE, ISO, ASTM).
3. Weight Calculation
Weight (kg/m²) = × Sheet Width.
Example: A 0.4mm galvanized sheet (Z275 coating) weighs 3.14 kg/m². For sheet plastic roofing with stone coating, add 0.8 kg/m².
4. Corrosion Resistance & Anti-Rust Mechanism
While the zinc-aluminum coating provides robust rust protection, localized corrosion may occur due to:
- Mechanical Damage: Scratches exposing the steel substrate require touch-up with zinc-rich paint.
- Galvanic Corrosion: Avoid contact with copper or untreated carbon steel in humid environments.
- Chloride Exposure: Coastal areas necessitate higher zinc coatings (Z450+). The self-healing property of zinc ensures minor scratches re-passivate over time.
Manufacturing Process
- Material Selection: ASTM DX51D steel coils sourced from ISO 9001-certified mills.
- Galvanizing: Continuous hot-dip process (435–455°C) with zinc/aluminum alloy coating.
- Profiling: Roll-forming into corrugated/embossed patterns for enhanced rigidity.
- Stone Coating (optional): Acrylic-bonded natural granules applied at 200°C for UV resistance.
- Quality Assurance: Eddy-current coating checks and salt-spray testing (1,000+ hours).
Applications
- Industrial Roofing: Factories, warehouses, and hangars requiring high load-bearing capacity.
- Agricultural Buildings: Resistant to ammonia corrosion in barns and poultry farms.
- Residential Use: Aesthetic stone-coated variants for villas and log cabins.
- Solar Panel Mounting: Structural compatibility with photovoltaic systems.
