DUO Column Formwork


The DUO system formwork is characterized by its low weight and extremely simple handling. Not only the material used is very innovative, but also the entire concept: with a minimal number of different system components, walls, columns and slabs can be easily and efficiently formed with only a minimal number of different system components. DUO is the optimal solution for small-sized components with lower surface requirements as well as for restoration work where no crane can be used.

Besides the panels including the formlining, most DUO accessories are made of the new innovative composite material with a polymer basis. This material is extremely light and, at the same time, has a high load-bearing capacity.

Apart from the material, the developers focused on ensuring that the formwork system was easy to handle. Almost all operations with DUO can be carried out without tools, and the working steps are easy to understand. Even less experienced users of system formwork can work quickly and efficiently with DUO. The fact that the majority of system components can be used for walls, columns and slabs additionally increases the performance. Last but not least, DUO reduces noise pollution on the construction site – an important aspect, for example, on inner-city construction sites.
