Heavy Duty Bond Tile Stone Coated Metal Roof
The Heavy Duty Bond Tile is an advanced composite roofing material engineered with a classic scalloped profile, uniquely enhanced by a precise central stiffening rib within each arc. This geometric reinforcement offers the timeless aesthetic of traditional tiles while delivering industrial-grade impact resistance and structural rigidity. The core consists of high-quality Galvalume steel (PPGL), completely coated with high-temperature sintered natural basalt stone chips and bonded with a premium acrylic resin system.
Backed by 11 years of manufacturing expertise, our factory operates 6 fully automated, high-precision production lines, maintaining a stable weekly output of over 140,000 pieces. Manufactured under strict ISO9001 quality management systems, this product carries comprehensive international trade compliance certifications including CE, SONCAP, and COC. It is the ultimate heavy-duty roofing solution, offering global distributors and project developers a highly durable system designed to withstand extreme weather and heavy physical impacts.

Key Technical Features
1. Central Stiffening Rib & Impact Resistance
Engineered Structural Reinforcement: The defining feature of the Heavy Duty Bond Tile is the recessed crease—or stiffening rib—stamped precisely down the center of each convex curve. This geometric enhancement acts as a primary structural support, massively multiplying the panel’s rigidity and resistance to downward impact (such as heavy hail strikes or foot traffic during roof maintenance) without adding extra weight to the building structure.
Dimensional Stability: The addition of the central rib minimizes the risk of metal warping or denting over time, ensuring the roof maintains its pristine, uniform architectural lines for decades.
2. Extreme Environmental Tolerance
Aerodynamic Wind Defense: The continuous undulating profile seamlessly interlocks to create a tight, unified roof matrix. When installed with standard batten systems, the aerodynamic ridges and reinforced grooves help to disrupt and deflect high-velocity winds, offering exceptional defense against hurricane-force uplift.
Corrosion & UV Defense: The high-grade aluminum-zinc alloy electroplating creates a dual protective film on the steel plate. Paired with high-temperature sintered basalt granules, it ensures zero rusting and vibrant color durability under intense UV exposure or in harsh marine environments.

In general, there are 3 main parts of raw material contents:
① Stone Chips ( Beautiful look, effective heat / UV resistant, noise reduction, anti-slip and etc features)
② Galvalume Steel Plate ( Eco-friendly and recyclable material, strong, light-weight, anti-corrosion, waterproof)
③ Acrylic Glue ( Premium sealing performance, strong adhesion, anti-algae)
Supply Chain & Quality Control (QA/QC)
Premium Raw Material Supply: Our metal substrates are sourced from leading domestic steel mills, guaranteeing the yield strength and coating uniformity of the steel from the source.
Automated Production Control: Our 6 continuous production lines utilize automated spraying and constant temperature baking processes. This minimizes batch to batch variation, ensuring consistent acrylic resin thickness and strict adherence to factory standards for stone chip adhesion.
Authoritative Compliance: To meet the access requirements of different countries, every shipment is supported by comprehensive CE, ISO9001, SONCAP, and COC testing reports and documentation to facilitate rapid customs clearance.
Logistics & International Packaging Standards
To ensure cargo integrity during long-distance ocean freight and multimodal transport, we provide standardized, heavy-duty export packaging solutions:
Packaging Format: Fumigated wooden pallets for export + multi-layer PE waterproof wrapping + overall steel strapping reinforcement. Inner packaging can be customized (e.g., 10 pieces per bundle) according to procurement requirements.
Pallet Load Capacity: Standard loading capacity ranges from 500 to 900 pieces per pallet (optimized based on steel thickness and destination port weight limits).
Container Loading Efficiency: A standard 20ft General Purpose (GP) container can accommodate a maximum of 20 pallets. Our logistics team provides precise loading plans tailored to different national port weight regulations, maximizing container volume utilization while preventing cargo shifting during transit.
Why Stone Coated Metal Roof？
50
years
0.4-0.8mm thick steel sheet with 150g/m2 galvanized aluminum zinc rust-proof coating, providing A-grade rust resistance, lifespan of 50 years without corrosion or perforation.
Noise Reduction
Same sound insulation ability as ceramic roof tiles or asphalt shingles, no need to be disturbed by the sound of rain.
fire proof
Made of steel material, A-class fire resistance, safer and more reassuring.
Hail Prevention
Ceramic tiles or PVC tiles can be damaged in hail weather, but for metal tiles 0 worry!
Hurricane Resistance
Lightweight yet sturdy, able to effectively withstand strong wind of 60-80MPH.
Weather Resistant
With UV resistant high quality surface glue, and high temperature colored baking stone chips, 15+ years no worry of color fading issue.
light weight
Only 5-8Kg per square meter, the weight is only 16% of traditional ceramic tiles, greatly reduces the load-bearing capacity of building structures.
Environmental
Metal material and natural stone, without any pollution issues.
Low Maintenance
No damage or other minor issues, benefit from one installation for a lifetime.
Cost Effective
Compared to other types of roof tiles, there is no significant increase in cost.
