Granite for Staircase Supplied to Mumbai
Precision-calibrated gangsaw slabs engineered for staircase durability, stain resistance, and timeless luxury aesthetics.
Engineered Granite Solutions for Staircase
The stone staircase is the architectural centrepiece of any grand home — where craftsmanship, material quality, and visual impact converge.
At Granite Gallery, we supply large-format gangsaw slabs (up to 3200×1800mm), precision-cut tiles, and bespoke edge profiles processed at our Kishangarh facility to exact millimeter tolerances.
- High Load Strength
- Compressive strength of 200–230 MPa, ensuring zero cracking under heavy structural loads.
- Precision Calibration
- Uniform 18mm/20mm thickness calibration prevents uneven lippage and minimizes installation labor.
- Door-to-Site Transit to Mumbai
- Delivered safely in heavy-duty wooden A-frames within 2–3 days express trailer transit.

Technical Specifications & Requirements for Staircase
Proper installation guarantees that your granite staircase performs flawlessly for decades without cracks, stains, or hollow tiles.
- Structural sub-frame
- Bed treads onto a sound concrete or steel-framed stair designed to carry the added dead load of solid stone
- Tread thickness
- Use a minimum 30mm for cantilevered or open treads and 20mm for fully supported treads, sized to the going
- Uniform rise & going
- Keep every riser height and tread depth consistent to building-regulation tolerance — uneven steps are a trip hazard and a defect
- Anti-slip nosing
- Detail an anti-slip nosing (grooves, inset strips or a bull-nose) on every tread front edge — essential on polished stone
Architectural Staircase Installation Guide
Engineered laying practices to prevent hollow spots, cracks, and moisture staining.
Sub-Floor Curing & Leveling
Ensure the concrete substrate is fully cured (minimum 28 days) and free of dust. Never lay heavy stone over uncured or uneven screeds.
Polymer-Modified Adhesive
For white marbles and light granites, use specialized white adhesive instead of grey cement to avoid dark hydration staining bleeding through the stone.
Expansion Joints & Grouting
Maintain 2mm expansion joints across large floor spans to absorb seasonal temperature expansion, preventing tiles from lifting or tenting.
Impregnating Nano-Sealer
Apply a solvent-based penetrating impregnator within 48 hours of grouting to seal microscopic pores against oil, turmeric, and acidic spills.

Have a Custom Question? Chat UsCantilevered floating staircases require a minimum stone thickness of 30mm, along with an internal structural steel anchor support, to handle high torsion and loads safely.
We can mill subtle anti-slip grooves near the front edge of each tread, apply sandblasted safety bands, or process the tread surface to a honed finish while keeping the riser polished.
