Overview

Stair treads

The maximum length of a step is 150 cm. Tread and riser dimensions are brought to the project dimensions with millimetre precision.

Depending on indoor or outdoor use, the surface is ground to the finish you want: polished, honed, patinato or sandblasted. Treads are packed on wooden pallets and made ready for long-distance shipping.

Our stair treads are made to TS EN 15285, the standard for agglomerated stone modular tiles for internal and external flooring and stair cladding.
