Terrazzo Stair Designs: Types of Precast Terrazzo Stairs

Different Types of Terrazzo Stairs

Terrazzo Stair Designs

There are different types of terrazzo stair designs, each of which can be customized for any institutional, commercial, or industrial setting. Concord Terrazzo Company fabricates precast stairs in-house, using TERRAZZCO Brand aggregates and epoxy, and then transports the stair material to a project’s site. Before we dive into the types of stairs we can design, let’s discuss the difference between a stair tread and a riser.


A stair tread is the horizontal surface of the staircase, or as many would call the step. These treads can include abrasive strips, which help prevent people from slipping as they travel up and down the stairs.  There are special stair treads to consider as well.  Steps such as landing and winding treads provide a change in direction along the stairway.



In contrast to a tread, a riser is the vertical component of the stair that provides support to the treads.

Types of Terrazzo Stairs

Straight Stairs


A straight stair connects the ground-level floor to an upper-level floor with no change of direction. Sometimes when the stairs are 12 feet or higher, an architect can add a central landing. Central landings provide a stopping point for pedestrians between two flights of stairs.  These stairs are among the easiest to build for any architectural project.

Quarter Turn Stairs


Quarter turn stairs bend at an intersection at a 90-degree angle.  With a change in direction, these steps are more visually appealing and flexible for an architect to work with than straight stairs.  In most buildings, quarter-turn stairs are commonly located in a corner of a room.

Half Turn Stairs


Half-turn stairs are quite beautiful themselves, offering architects even more flexibility in their designs. These types of stairs connect to either a landing or an additional flight of stairs. The extra flight of stairs is known as quarter landing stairs. The main difference between these stairs and the quarter turns is the directional turn. For half turns, a pedestrian must make a 180 degree turn to continue their path up or down the stairway.

Winder Stairs


Winder treads are similar to quarter turns except that landing is a bit different. Instead of having a flat landing, the landing curves in a way that makes the corner piece more triangular in shape.

Curved Stairs


These stairs curve at an angle, but never do make it back into a full circle.

Spiral Stairs


Similar to the curved stairs yet different. These treads form a circular movement around a pole.
