Quarried from significant mineral deposits in Fujian Province, China, this variety of G664 Granite Stair Riser is a worldwide standard for predictable and durable architectural trim. It offers a stable geological profile that resists environmental pollutants and mechanical impact, making it an essential choice for large-scale projects requiring hundreds of matching units. The material functions as a more uniform and refined alternative to G648 pink granite, providing a professional medium for vertical architectural planes.

Visual character is defined by a consistent pinkish-brown matrix infused with medium-grained charcoal and white mineral points. This homogeneous distribution ensures that the vertical riser face matches perfectly with adjacent treads, creating a cohesive visual flow in high-traffic staircases. The stone's high crystalline density allows it to hold a high-gloss polish for luxury interiors or a textured bush-hammered finish for slip resistance in public outdoor stairs, effectively concealing evidence of daily wear in transport hubs.

Typical Applications

• Commercial stair risers for high-traffic shopping malls and corporate offices.
• Public municipal stairs where flamed or bush-hammered risers enhance safety.
• Luxury residential staircases requiring color matching with Bainbrook Brown flooring.
• Architectural trim and vertical skirting sections in large-scale commercial lobbies.

Procurement involves a reliable 15–25 day production lead time, supported by large-volume quarry capacity in Fujian. Riser components are precisely cut using automatic infrared technology to ensure zero-tolerance height calibration during site installation. Every unit is bundled in seaworthy crates with reinforced strapping to ensure safe delivery to international project sites. Prioritize the 15–17cm height variant for standard international building code requirements in commercial stair construction.
