Stairs & Enclosures

Stairs

Stairs

Precast concrete stairs are used in any application where a stair tower or individual steps are required. These modules can provide fast erection and durable access in buildings or parking structures.

They are typically 6 to 10 inches thick and are made as “open-Z” components, in which the upper and lower landings are cast monolithically with the tread/riser section. They also can be cast as shorter components, consisting of only the tread/riser section, which is supported by separate landing components that span transversely to the stair section.

Stair components are typically cast either “on edge” or “upside down.” The format will depend on the size and the producer’s preferred production method. Abrasive nosing pieces are often cast into the treads to create a non-slip surface.

When cast on edge, the tread and bottom remain as cast and typically will remain as such in the final construction. When they are cast upside down, the bottom will be troweled to the desired degree of smoothness and typically will remain exposed to view in the final construction.

Elevator Enclosures

Elevator enclosures consist of solid precast concrete panels designed to provide fire protection around stairways and elevator cores as required by buildings codes.
