Precast Concrete Stairs

Stair flights and landings cast in our plants, delivered ready to set.

Overview

What are precast concrete stairs?

Precast concrete stairs are stair flights, landings and stair towers cast in a plant, then delivered and set in place by crane. Treads, risers, nosings and landings arrive finished, with embedded plates and connections already cast in.

Concrete is durable, fire resistant and quiet underfoot, which makes precast stairs a common choice for exit stairs in parking structures, apartments, schools, offices and public buildings. Surfaces can be given a non-slip finish, so safety and durability are built in at the plant.

Stairs can usually be installed early in the schedule. That gives crews safe access to upper floors during construction, and it removes the need to form, pour and cure stairs on site. Our Tampa plant publishes load tables for precast stairs in the resource library. Because the stairs are built under controlled conditions, treads and risers are uniform and edges are crisp, and there is no formwork to build or strip on site. That also means fewer trades working on the stair at the same time, which keeps the site safer and the schedule shorter.

Resources

Design data and guides

See the Tampa stairs load tables and our resource library for details and specifications. To understand how stairs tie into the structure, read precast concrete connections explained. The Precast/Prestressed Concrete Institute publishes the industry design standards our plants follow.

Process

From design to delivery

Precast concrete stairs start with the stair layout: flight lengths, riser and tread sizes, landings and the supports they bear on. Each flight and landing is then cast in a form in the plant, with embedded plates and connections cast in, cured under controlled conditions and checked by our quality staff.

Our plants follow the quality programs of the Precast/Prestressed Concrete Institute, so every flight meets the same dimensions and strength requirements.

Stairs are trucked to site when the structure is ready for them. A crane sets each flight and landing, and crews connect it to the supports. Coreslab provides delivery, installation, finishing and detailing, so one team can carry precast concrete stairs from the plant to a finished stair.

Questions

Precast concrete stairs: common questions

Can precast concrete stairs be used during construction?
Stairs are often installed early, which gives crews access to upper floors. Use before the building is finished should be approved by the engineer and the contractor.

What surface finishes are available?
Treads can be given a non-slip finish at the plant. Ask your nearest plant which textures and finishes it offers.

How are precast stairs installed?
A crane sets each flight and landing onto its supports, where it is connected to the structure. Our guide to how precast concrete is installed covers the process.

Are precast concrete stairs fire resistant?
Concrete does not burn, which is why it is widely used for exit stairs. Your design team confirms the rating required for your building.
