Quarried from the prolific mineral deposits of Fujian Province, this coordinated assembly of G664 Granite Steps & Risers represents a professional solution for large-scale vertical circulation projects. The material is geologically classified as a medium-grained intrusive rock, prized for its extreme compressive strength and resistance to mechanical impact. It functions as a more uniform and predictable alternative to G648, facilitating precise pattern matching across multi-flight stair runs in high-occupancy commercial developments.

The visual matrix displays a warm reddish-brown base consistently populated by charcoal and ivory mineral points. These mineral clusters create a non-directional texture that effectively hides evidence of daily wear, ensuring the stairs retain their professional appearance under heavy pedestrian load. In its flamed state, the heat-treated surface provides essential traction for outdoor public safety, while the polished finish highlights the crystalline depth for luxury interior staircases.

Typical Applications

• Commercial shopping mall staircases requiring high durability and color consistency.
• Public municipal stairs where flamed treads provide essential anti-slip safety.
• Executive office building entries where matched risers ensure a cohesive aesthetic.
• Residential multi-unit housing stairwells requiring a stable, weather-resistant mineral.

Available Formats

• Finish options: Polished, Honed, Flamed
• Thickness: 2cm (step treads), 3cm (heavy-duty treads)
• Slab/tile sizes: Treads: 126x30cm, 130x33cm, 120x33cm; Risers: 126x15cm, 130x15cm, 120x15cm

Buyer Notes

• Suitability: Coordinated stair components for heavy-duty commercial and municipal projects requiring matched treads and risers.

Logistics for these complete stair systems involve precise batch-matching to ensure the tread and riser units align perfectly in both tone and texture. Components are precisely cut using automatic infrared technology to ensure zero-tolerance height and width calibration for site installation. Every set is bundled in seaworthy crates with reinforced corner protection to prevent edge chipping during transit. Prioritize the 3cm heavy-duty treads for public infrastructure projects to ensure maximum structural support under load.
