Stone Clad Metallic Roofing Shingles

一、Fireproof Roofing Sheets

Fireproof roofing sheets utilize a mineral-fiber core that withstands 1,200°C for 2 hours (ASTM E119), achieving Class A fire rating. The steel substrate is coated with intumescent paint that expands when heated, sealing gaps during wildfires. Ideal for oil refineries and forest-adjacent resorts, these sheets prevent ember penetration and reduce fire spread velocity by 70%.

二、Technical Specifications: Thickness & Weight 

Our stone coated metal roof tiles are available in a range of steel substrate thicknesses to suit different project requirements, from lightweight residential renovations to heavy-duty commercial applications. The table below outlines the correlation between steel thickness and unit weight per tile.

Key Considerations for Selection

Structural Load Capacity:
Thicker tiles (0.35mm–0.60mm) provide greater rigidity and resistance to deformation under heavy snow loads or foot traffic during maintenance. Always verify your building's structural capacity before selecting heavier gauges.

Cost vs. Longevity:
While thinner gauges (0.18mm–0.25mm) offer lower initial costs, thicker substrates (0.30mm+) typically provide longer service life and better resistance to physical damage, potentially reducing long-term maintenance expenses.

Installation Compatibility:
Ensure that the chosen thickness is compatible with your existing roof structure and fastening system. Thicker tiles may require adjusted nailing patterns or additional support in certain applications.

Customization Available:
If your project requires a specific thickness not listed above, please contact our team. We can accommodate custom gauge requests for large-volume orders to meet unique engineering specifications.

Note: Weights are approximate and may vary slightly based on tile profile design and stone granule density. All measurements are subject to standard manufacturing tolerances.

Non-combustible basalt granules (ASTM E136) eliminate toxic fume risks. Our factory provides fire safety documentation including IMO FTPC Part 5 certificates for maritime applications. Installation requires no special tools – standard screws with EPDM washers ensure airtight sealing.
