方格型 · Structured grid texture — /products/grid.html
A crisp, structured grid texture — clean and architectural. The Grid profile reads as orderly and substantial, a strong fit for modern homes and public buildings.
The Grid is the architectural choice — a regular, structured pattern that looks orderly and substantial on larger roofs and public buildings.
A regular, squared grid texture that reads as orderly and substantial. It suits larger roof planes and public or commercial buildings where a busy wave would look restless.
At roughly 2.6–3.0 kg per tile and ≈ 2.1 tiles/m², the finished roof is a fraction of the weight of clay or concrete — so it can go straight over an existing roof without reinforcing the structure.
The surface is natural basalt stone granules, not paint. Dark basalt blocks UV at the rock itself, and a clear acrylic over-glaze seals every chip — so color holds for decades instead of chalking like a painted metal sheet.
The interlocking steel body is rated to the highest external-fire class and stands up to high-wind zones. Recommended roof pitch ≥15°; profiles ship flat-packed and container-optimized for export.
Every Grid tile is built up from a Galvalume core to a sealed stone surface — the same structure the world's premium stone-coated brands use.

Certification marks indicate the standards this profile is built and tested against; project-specific third-party reports are issued per order and market.
The colors used across our project references. Color comes from mineral granules, not paint, so it resists UV and acid rain. Custom shades matched to RAL / Pantone from 300–500 m² MOQ.
Screen colors are indicative — request a physical sample kit before specifying. Quoted color durability: ΔE ≤ 3 over 10 years on standard shades, ΔE ≤ 2 achievable on custom.
