Bespoke Precast Concrete Stair Flights

Precast concrete stairs are manufactured off site in controlled factory conditions and delivered as complete structural stair flights. They provide a durable, accurate and efficient alternative to casting concrete stairs in situ.

The existing One Stop Consult service offers straight and cranked stair flights, with the option for an integral slab at the top or base of the stair. Treads, risers, widths, landings and support details can be manufactured to the project specification.

Stair flights are cast in timber or steel moulds and finished with a trowelled surface. Units can also be designed to coordinate with other precast flooring and structural components for an accurate fit on site.

Key Advantages

Why Choose Precast Concrete Stairs?

Precast stair flights combine quality-controlled manufacture with fast installation and dependable structural performance.

01

Factory-Controlled Quality

Units are manufactured in controlled conditions, supporting consistent dimensions, finish and concrete quality.

02

Bespoke Design

Stair flights can be formed around the required rise, going, width, landing arrangement and structural support conditions.

03

Rapid Installation

Complete flights can be craned into place quickly, reducing the need for extensive in-situ formwork and curing time.

04

Durable Construction

Reinforced precast concrete provides a robust and low-maintenance stair structure suitable for high-traffic areas.

05

Integrated Landings

An integral slab can be formed at the top or bottom of the flight where this suits the structural design.

06

Precast Coordination

Stairs can be designed alongside hollowcore, beam-and-block and other precast elements for coordinated installation.

Available Configurations

Precast Stair Flight Options

The final arrangement is manufactured around the architectural and structural requirements of the project.

Straight Stair Flights

A single linear flight manufactured to the required floor-to-floor height, tread, riser and width dimensions.

Cranked Stair Flights

Shaped flights incorporating a change in geometry or support detail to suit the stair core and adjoining floor construction.

Integral Top Landing

A landing slab can be cast as part of the stair unit at the upper end where this suits the design and lifting strategy.

Integral Bottom Landing

The lower end of the flight can incorporate a slab or landing section where required.

Project-Specific Treads and Risers

Dimensions are manufactured to the supplied specification and should comply with the approved stair design.

Custom Widths and Profiles

Stair width, soffit profile, nosing and edge details can be developed around the project requirements.

Manufactured in Timber or Steel Moulds

The original OSC page confirms that the stair flights can be cast in timber or steel moulds and finished with a trowelled concrete surface.

The mould type and production method are selected to suit the geometry, finish, repetition and quantity required. Accurate approved drawings are essential because the unit is cast to project-specific dimensions.

Detailed Design and Structural Coordination

Precast stairs must be designed around the approved architectural geometry and the supporting structure. Floor-to-floor heights, finished floor levels, landings, bearings, connections and temporary stability all need to be confirmed before manufacture.

The design should also coordinate with headroom, guarding, handrails, finishes, fire strategy, acoustic requirements and the surrounding precast or in-situ floor construction.

How the Precast Stair Supply Process Works

Clear drawings and confirmed structural information allow the manufacturer to prepare an accurate quotation and production design.

Review architectural, structural and stair-core drawings.
Confirm floor levels, rise, going, width and landing geometry.
Coordinate bearings, connections, lifting points and support details.
Prepare the manufacturer's stair drawings for approval.
Approve the design before mould manufacture and casting.
Arrange haulage, craneage and installation to suit the programme.
1

Project Review

Assess the stair geometry, support conditions, access and performance requirements.

2

Quotation

Coordinate pricing for design, manufacture, delivery and any required installation scope.

3

Detailed Design

Prepare stair geometry, reinforcement, bearings, lifting and connection details.

4

Approval and Manufacture

Approve the production drawing before the unit is cast and finished.

5

Delivery and Installation

Deliver using specialist haulage and install using suitable lifting equipment where included.

Preparing for Delivery and Installation

Precast stair flights are heavy structural units and normally require crane installation. The supporting structure must be complete, stable and ready to receive the unit before delivery.

Vehicle access, lifting radius, crane position, bearing levels, edge protection and temporary stability should all be planned before the installation date.

Supporting structure complete
Bearings formed to approved levels
Dimensions checked before manufacture
Delivery and crane access confirmed
Suitable lifting plan prepared
Temporary stability arrangements agreed
Safe installation zone available
Approved stair drawing on site
Finishes and Interfaces

Coordinating the Completed Staircase

The precast flight forms the structural stair, but the complete staircase also includes finishes, guarding and surrounding interfaces.

Tread Finishes

Tiles, stone, resin, carpet or other finishes should be allowed for when setting the final riser dimensions.

Handrails and Guarding

Fixing zones, edge distances and cast-in details should be coordinated before manufacture where possible.

Wall and Landing Junctions

Interfaces with masonry, steel, concrete and precast floors must match the approved structural details.

Fire Strategy

Stair geometry, enclosure, fire resistance and escape requirements must align with the project fire design.

Important Precast Stair Information

Final stair geometry, reinforcement, bearings, lifting points, fire resistance and connection details depend on the project-specific architectural and structural design. Finished floor levels and applied finishes must be confirmed before manufacture. Approved production drawings should be checked by the relevant project team before casting. Delivery access, craneage, lifting operations, temporary stability and safe installation remain subject to the agreed scope and contractor responsibilities. One Stop Consult provides consultancy, coordination and supply-chain support through specialist precast partners.

Frequently Asked Questions

Precast Concrete Stair FAQs

What are precast concrete stairs?

They are reinforced concrete stair flights manufactured off site in a mould and delivered as complete structural units.

Can you provide straight and cranked stair flights?

Yes. The existing OSC service confirms that both straight and cranked stair flights can be manufactured.

Can a landing be cast as part of the staircase?

Yes. An integral slab can be provided at the base or top of the stair flight where the project design permits.

Are the stairs made to bespoke dimensions?

Yes. Treads, risers, width, landings and overall geometry are manufactured to the approved project specification.

What finish is provided?

The existing service describes stair flights cast in timber or steel moulds with a trowelled concrete finish.

Is detailed design available?

Yes. Detailed design support is available to coordinate the stair flight with the architectural and structural requirements.

Is installation available?

Yes. Professional installation can be offered subject to project location, access, programme and agreed scope.

What information is needed for a quote?

Provide plans, stair sections, floor-to-floor heights, finished floor levels, structural support details, delivery address and programme.

Can precast stairs coordinate with other precast flooring?

Yes. Stair flights can be designed alongside hollowcore and other precast systems so the components fit together on site.
