1. Product Introduction
Stone coated metal roof sheet is a new-generation high-performance roofing material that adopts high-grade galvalume steel sheet as the base substrate, bonded with high-temperature sintered natural basalt stone granules via imported acrylic adhesive. It perfectly combines the high strength of metal materials, the weather resistance of natural stone and the decorative beauty of traditional roof tiles. Integrating waterproof, anti-corrosion, heat insulation and fireproof functions, it replaces traditional clay tiles, concrete tiles and asphalt shingles. With standardized modular design and diverse styles, it is a durable, energy-saving and eco-friendly building roofing solution for modern construction and old roof renovation.
2. Core Product Advantages
Lightweight & Structural SavingThe tile is ultra-light, only 1/3 weight of clay tiles and 1/6 of concrete tiles. It greatly reduces building roof load, requires no secondary reinforcement of roof beams, cuts construction costs and shortens project cycle, suitable for new buildings and old roof reconstruction.
Super Anti-corrosion & Long Service LifeMade of AZ100-AZ150 alu-zinc steel substrate with professional passivation anti-rust treatment. It features excellent salt spray resistance and acid and alkali resistance, effectively avoiding rust and cracking. The sintered stone granule surface is UV-resistant and aging-resistant, with no fading, chalking or sand peeling for 30-50 years.
Strong Windproof & Waterproof PerformanceAdopts exclusive upper-lower and left-right interlocking occlusion structure with fully sealed overlapping joints. Multi-point nail fixing design realizes overall waterproofing, effectively resisting heavy rain, strong wind and typhoon weather. No water leakage or tile falling occurs in extreme weather.
All-weather Resistance & High SafetyIt adapts to extreme temperatures from -40℃ to 80℃ without cracking or deformation. It has outstanding hail impact resistance, not easy to dent or damage. The metal substrate reaches Class A fireproof standard, non-combustible and high safe. Meanwhile, the natural stone layer absorbs rainwater impact noise, realizing silent rainproof effect.
Energy Saving & Heat InsulationThe natural stone coating can reflect sunlight and isolate external heat. The air convection gap under the tiles forms a natural heat insulation layer, which significantly reduces indoor temperature, lowers air conditioning energy consumption and achieves energy-saving and cooling effects.
Easy Installation & Zero MaintenanceStandardized size and flexible interlocking structure enable fast laying with simple construction process. After installation, the roof is free of rust, crack and moss growth, requiring no regular maintenance and renovation, saving long-term after-sales cost.
Eco-friendly & CustomizableAll raw materials are non-toxic and environmentally friendly without volatile harmful substances. The metal substrate is 100% recyclable. Multiple tile profiles (Roman, slate, ripple, shingle) and customized colors are available to match various architectural styles.
3. Wide Application Scenarios
Residential BuildingsIdeal for villas, private houses, rural self-built houses and high-rise residential roofs. It has elegant appearance, diverse colors and stable performance, improving building grade and living comfort.
Commercial & Industrial BuildingsWidely used in factory workshops, warehouses, office buildings, shopping malls and tourist scenic area buildings. It meets the large-area roofing demand with low cost, fast construction and long durability.
Old Roof Renovation ProjectPerfect for flat-to-slope renovation, old tile roof replacement and rusty color steel tile renovation. Light weight avoids structural transformation, realizing rapid renovation and beautiful upgrade.
Special Environment ProjectsApplicable to coastal areas (anti-salt spray corrosion), rainy and high-temperature areas (weather resistance), and high-altitude windy areas (typhoon resistance). It stably adapts to various harsh climatic environments.
Public & Cultural BuildingsSuitable for schools, hospitals, parks, pavilions and historic building renovation. It balances decorative effect, safety performance and environmental protection requirements.
