Why TERRAZZCO Terrazzo Tread and Risers Combo Set?

Concord Precast Terrazzo produces custom terrazzo stair treads and risers combo sets or accents poured in place terrazzo floor, which creates a seamless flow from a staircase to the flooring surface. Abrasive channels are cut into the surface of the tread and filled with TERRAZZCO Brand Epoxy Resin and silicon carbide to provide an anti-slip surface. With custom sizes and thicknesses available, architects and designers can fully customize each unit in virtually any color using TERRAZZCO Groutless® EZPour Epoxy 158 and choice of aggregates.

Concord Terrazzo professionals collaborate closely with customers to design stair treads that meet local building codes while manufacturing a customized solution that addressed the need for safety and comfort.


Stair treads refer to the horizontal pieces that form the stairs. This is the surface people will walk on. The stair risers are the vertical pieces of the stair. Together, stair tread and riser combinations craft beautiful staircase designs that can connect multiple stories of any building and can include stair landings that support rest or call for a change in direction. Concord Precast stair treads are designed for high performance in areas with large traffic volumes
