Stair Treads

Our stones are often specified for both interior and exterior stair treads and risers because of their hardness, durability, excellent performance characteristics and natural beauty. And because we produce custom sizes and offer several finishes, architects also appreciate the flexibility our materials afford them in their designs.

Stair Treads Projects



Stair Treads – Stair treads are generally custom-fabricated from large stones.

Risers – Risers are generally custom-fabricated but occasionally are simply cut from field tiles.

Stringers – Stringers are custom-fabricated. Like base complements flooring, stringers complete the appearance of a stone staircase.

weathering characteristics

Some materials are “unfading”, meaning they will hold their basic color even after many years of exterior use. Others are “weathering” or “semi-weathering”, meaning they will change color (usually to shades of brown) when used outside. A stone’s weathering characteristic is primarily an aesthetic consideration. “Weathering” in and of itself does not adversely affect the performance or durability of a stone. See stones below for weathering characteristics.


Depends on stone selected. See stones below for available finishes.


Custom sizes depend on stone selected, finish, thickness, joint width and other factors. Radiused – and irregular -shaped treads also available.


Depends on use, stone selected, finish, piece size, setting method and other factors. Generally slate treads are at least 1” thick, risers are usually 3/4” thick.

edge details

We fabricate many different edge details. Usually any exposed edge is honed.

joint widths

Depends on stone selected, finish, piece size and other factors.
