Description
Our curved stone stair components are engineered for architectural precision, producing sweeping curved steps, spiral staircase elements, and circular stair wells that define grand staircases. Each piece is CNC-cut from natural stone blocks to exact radius specifications.
Product Range:
- Curved Steps — single-piece curved treads with any radius
- Spiral Stair Cores — central stone columns for spiral installations
- Landing Platforms — curved and irregular-shaped landings
- Winder Steps — pie-shaped treads for curved transitions
- Curved Stringers — supporting structural elements
- Baluster Rows — matching stone balusters for curved runs
Materials:
- Marble — polished finish for grand interior staircases
- Granite — recommended for high-traffic and exterior stairs
- Travertine — warm tones for residential grand stairs
- Limestone — classic choice for historical restorations
Manufacturing Process:
- 3D scanning or CAD drawings for precise radius calculation
- CNC cutting for accurate curved profiles
- Multi-stage polishing for consistent finish on curved surfaces
- Anti-slip surface treatment options (grooved, sandblasted)
- Pre-fitted numbered pieces for fast installation
