Stairs

Outdoor Natural Stone Stairs

As a professional stone trading supplier, we understand that outdoor staircases are more than just functional walkways—they are a defining feature of your building facade and landscape design. Sourcing high-quality natural granite, we deliver exterior stone stair solutions that combine uncompromising safety, exceptional durability, and versatile design flexibility for global buyers.

Professional Anti-Slip Finishes for Outdoor Safety
With variable outdoor conditions, pedestrian safety during wet or icy weather is our top priority. To meet the specific demands of exterior stairs, we offer two extensively field-proven surface treatment options:

• Flamed Finish
  Created by blasting the stone surface with high-temperature flames, causing the mineral crystals to explode and form a uniformly rough texture. This finish achieves an R11 slip resistance rating, with a static friction coefficient exceeding 0.8, effectively handling daily outdoor pedestrian traffic. It is also relatively easy to clean and boasts excellent weather resistance and freeze-thaw stability, making it the preferred choice for commercial plazas, villa entrances, and standard outdoor applications.
• Bush-hammered Finish
  This process involves mechanically hammering the surface to create a dense pattern of pitted dots, similar to the skin of a lychee. It offers a softer touch while delivering even more outstanding anti-slip performance, reaching an R12 slip resistance rating. This superior grip makes it ideal for pool surrounds, wet ramps, and public areas with the highest safety requirements, ensuring secure footing even in consistently wet environments.

Full Customization Capabilities, Breaking Design Boundaries
No matter how complex your project’s design requirements are, our extensive experience and mature craftsmanship enable us to deliver perfect results. We are not limited to standard straight stairs; we specialize in handling all types of custom designs：

Curved & Spiral Staircases: Utilizing high-precision laser positioning cutting technology (with an error margin of ≤0.2mm), we can precisely fabricate smooth curved treads and flowing spiral structures, creating an elegant visual focal point for luxury villas and commercial spaces.

Trapezoidal & Fan-shaped Treads: For irregular space constraints, we can customize non-standard trapezoidal or fan-shaped step slabs, ensuring every step fits perfectly against the building base for a seamless installation.
One-Stop Solution Service: From design deepening and layout optimization to precision machining, our technical team provides full-process support from measurement to delivery based on your drawings or concepts, ensuring the perfect restoration of complex designs.

We don’t just sell standard steps. With our advanced CNC machining centers, 5-axis waterjet cutters, and experienced technical team, we can realize any complex design you can imagine.

1. Curved & Spiral Staircases
   We specialize in processing curved and spiral staircases. Our precision machinery ensures that every curved tread and riser fits perfectly, with an error tolerance controlled within 0.5mm. We can handle both single-curve and complex double-curve (twisted) panels, ensuring a seamless, flowing appearance for your grand entrance.
2. Irregular & Special-shaped Panels
   No matter how unique your architectural drawing is, we can handle it. From angled corners to bespoke sculpted edges, we have the expertise to cut and shape the stone to your exact specifications.
3. Floating Staircases
   Achieve the ultimate minimalist “floating” effect. Our engineering team can precisely calculate the load-bearing structure to ensure that the cantilevered steps are not only visually stunning but also structurally safe and robust. We can pre-process the steps with hidden light grooves and glass fixing slots, ready for direct installation on site.
