Coated Metal Roofing Sheets

Stone Coated Metal Roofing Sheet is a modern roofing material that combines a high-strength metal substrate with natural stone granules. It offers the advantages of lightweight construction, long-lasting durability, and environmental friendliness. Thanks to its outstanding performance, it is widely used across a variety of architectural applications. Below are its core features and typical usage scenarios:

Core Features of Stone Coated Metal Roofing Sheet

1. Lightweight & High Strength
Weighing only 1/6 of traditional ceramic or cement tiles (approx. 6–7kg/m²), it significantly reduces the building’s structural load. It is especially suitable for old building renovations and earthquake-prone areas.
The base is made from aluminized zinc steel, offering excellent impact and corrosion resistance, with a lifespan of 30–50 years.

2. Weather Resistance & Safety
Withstands extreme temperatures (-30℃ to 70℃), hail, and strong winds up to Level 12 or 120 MPH.
Class A fire-rated and non-combustible. Its unique self-locking system and horizontal nailing technique enhance wind and seismic resistance, preventing tile displacement.

3. Aesthetic Appeal & Eco-Friendliness
The surface is coated with natural basalt stone chips, available in a variety of vibrant, fade-resistant colors. It combines the elegant texture of stone with metallic sheen, offering versatile decorative options.
All materials are 100% recyclable and the production process is eco-friendly, meeting green building standards.

4. Easy Installation
Simple to cut and bend, suitable for roof slopes from 15° to 90°. It can be installed directly over existing tiles, minimizing construction waste.
Dry-installation method requires only 4–6 nails per tile—fast, efficient, and cost-saving.

5. Functional Performance
Provides excellent sound insulation (reduces rain noise by up to 30%) and superior thermal insulation compared to standard metal roofing, improving indoor comfort.
Its multi-layer coating structure delivers excellent waterproof performance—ideal for regions with heavy rainfall.

Application Scope of Stone Coated Metal Roofing Sheet

1. Residential & Villa Construction
   Ideal for self-built homes, villas, and townhouses—especially in rural landscape renovations and “flat-to-pitched” roof upgrades, balancing aesthetics and function.

2. Public & Commercial Buildings
   Widely used in shopping malls, schools, hospitals, libraries, museums, office buildings, and clubs for its premium appearance and durability.

3. Rural & Western Regions
   Suitable for rural housing renovations in areas with strong winds and large temperature fluctuations, effectively preventing leaks and tile breakage.

4. Industrial & Temporary Structures
   Used in factories, warehouses, steel frame buildings, and quick-installation projects like prefab houses and temporary housing at construction sites.

5. Historic Building Renovation
   For old roof renovations, there’s no need to dismantle the original roof. Stone coated sheets can be installed directly over the old surface, reducing both time and cost.

Precautions

• Higher Initial Investment
  While long-term cost-effectiveness is better than traditional tiles, upfront costs should be considered in budgeting.

• Climate Adaptation
  Choose appropriate coating processes and base materials based on local climate (e.g., high-strength cold-rolled steel for western regions).

• Low Maintenance
  Periodic inspection of nail tightness and occasional rinsing with water are recommended to keep the surface clean and in good condition.

With excellent durability, environmental performance, and adaptability, Stone Coated Metal Roofing Sheet is becoming a superior alternative to traditional roofing materials—ideal for modern buildings across diverse climates and construction needs.
