Box type steel folding forms are specially designed to be used inside shafts of buildings. System solves the assembly, dismantling and lifting problems inside the shaft.

The foldable mechanism enables the system to be easily stripped from concrete and the formwork climbs to next level with the help of tower crane.

Practical assembly and stripping provides savings from labour costs and crane time. Steel box shaft forms could be used at openings up to 6 m width.
