Production

The pre-fabricated stair elements are produced custom-fitted in the factory and assembled at the construction site using load balancing four cable suspension gear. By using this efficient technology it is possible to have access to the next floor immediately. By building in pre-fabricated stair elements you save laborious lining and cladding work at the construction site. Pre-fabricated stair elements are produced in fairfaced concrete. Tiling or cladding with other materials afterwards is possible.
