The construction of cast in-situ concrete spiral and helical staircases can prove challenging without the use of the appropriate formwork. Bespokely manufactured formers can allow the complex geometry of the staircase to be created, whilst also achieving a soffit finish of sufficient quality to be left exposed. Each former is designed to meet the specific requirements of the project, including the size, shape, finish and number of re-uses required. Based upon this information our designers will select the most appropriate material for each former and create a 3D CAD model for approval.
We can also provide moulds for precast concrete spiral and helical staircases, please see the Patterns & Moulds section of our website for further details.
Once approved, the 3D CAD model can be converted in to CAM data allowing accurate manufacture of the staircase or soffit former via a range of technologies dependent on the selected material. Spiral staircase formers are manufactured using a wide range of materials from Filcor (Expanded Polystyrene) through to Glass Reinforced Plastic (GRP).
Used for the construction of cast in-situ reinforced concrete spiral and helical staircases and soffits.
