Stone Coated Metal Roof Cost

Durable Stone Chip Roofing

Durable stone chip roofing features a 0.45mm Alu-Zn steel core (AZ150 grade) and ceramic-coated basalt chips, delivering a 50-year lifespan—outlasting clay tiles by 200%. The sintered granules undergo “ceramization” technology, preventing color loss under UV exposure and reducing thermal expansion by 60%. Tests confirm resistance to 2,400 Pa wind pressure (Class F wind resistance) and 3,000 freeze-thaw cycles, making it suitable for alpine and desert climates. Fireproof ratings (Class A) and 99% acid rain resistance (pH 2–10) ensure safety in chemical plants or urban areas.

Installation requires no structural reinforcement due to lightweight design (6.05kg/m² vs. concrete’s 45kg/m²). Tiles (1,400mm × 420mm) include matching ridge caps, valley trays, and eaves drip edges for complete waterproofing. Our factory holds SONCAP and SGS certifications, with a daily output of 10,000 tiles for bulk exports. Case studies include hospital roofs in Rwanda and school projects in Saudi Arabia, where tiles withstood sandstorms and 50°C heat.
