What We Fabricate

We produce complete staircase sets from architectural drawings or on-site measurements. The fabrication package covers every stone element in the staircase — treads, risers, stringers (side slabs), landing slabs, and skirting at the base. All pieces are CNC-cut to your exact dimensions and delivered numbered for sequential installation.

Standard materials are Galala Extra, Silvia White, Triesta Grey, and Absolute Black Granite — all available from our own quarries. Any other stone in our catalogue can be used. Stone selection is typically driven by matching the floor material already specified for the project.

Common Questions

What is the standard thickness for stone stair treads?
For residential use: 3 cm is standard. For commercial and heavy-traffic stairs: 4–5 cm. Cantilevered treads may require 5–6 cm depending on span. We produce to your structural engineer's specification.
Do anti-slip grooves reduce the visual quality of the tread?
No — when machined precisely (3 grooves, 5×5 mm, at the nosing zone), the grooves are barely visible at normal viewing distance and do not affect the overall polished appearance of the tread. They are the standard specification for commercial stairs in most markets.
Can you match our existing floor marble for the stairs?
We can supply samples from candidate quarry faces before production. If your floor stone is a variety we quarry, same-batch production is possible. If you are matching stone supplied by another company, a sample matching process is required — allow 2–3 weeks before production confirmation.
Are the stair sets numbered for installation?
Yes. Every tread and riser in a staircase set is marked with a position number on the bedding face. A numbered installation drawing is provided with the shipment.
