Precast concrete stair cores are structural units designed to house stairwells. Two designs are available: stability cores, which provide lateral stability to the building structure; and freestanding cores, which act independently of the structural frame. These stair cores are built from L and T shaped precast walls and can incorporate box units. Stair cores are manufactured from self-compacting concrete for a high-quality finish and can be integrated with precast stairs and landings.

Features and benefits

  • Design support offered early in project development

Applications

  • Multi-storey buildings requiring stair access and structural core elements

  • Residential and commercial developments using precast construction methods

Physical attributes

Wall thickness depends on the stair core type, fire rating and number of storeys.
