Staircases are custom made to suit the client’s requirements with either flights supported off precast landings, which are built in, or flights with quarter landings attached onto steelwork supports. All units would can be offloaded and craned directly into place.
Precast flights are generally cast face down in variable steel moulds but can be cast on their side or face up to suit the client’s requirements. If the requirements of the staircase is outside of the parameters of the formwork system, then CCP will use bespoke steel moulds to achieve the necessary output. If applied architectural finishes are required, this can also be catered for,as shown in the architectural precast section of the website, as well as non-slip strips.
Connections between precast units are generally by halving joint. When connecting to insitu concrete frames, steel angles are usually used although there is the option to use invisible sliding stair connectors.
CCP has built a reputation for supplying high quality fairfaced concrete staircases for thousands of projects over the years and are justifiably proud of this reputation.
‘L’ shaped tread and riser units are also available and can be supported off blockwork walls each side. These are ideally suited to small works where no crane access is possible and for contracts with little or no repetition between units.
