Modular assembly system with exchangeable steel shuttering profiles for the production of diverse products, especially suited for door and window frames in variable dimensions.

Steel formwork are ideal for the production of precast concrete products with a high surface quality.

For the first time, the X-Uni-S system allows all the benefits of steel formworks, such as longer life, high surface quality, and reusability with the variability of wooden formwork panels. The X-Uni-S system consists of steel profiles which are held in place by MagnetBoxes with special adapters.

Various heights and profilings can be achieved by using extension rails with quick release fixings.

The X-Uni-S MagnetBox with system adapter is also compatible with the X-UNI system (shuttering of wooden formwork panels).

Individual variations and other dimensions are manufactured on request.
