The composite floor deck systems, HOLORIB and SUPERHOLORIB, consist of high-quality, corrosion-protected profiled steel and combine reinforcement, formwork and fire protection. In combination with the concrete fill, lightweight, highly load-bearing floors are created, which can be used for office and administration buildings, high-rise buildings, multi-storey car parks as well as school and university buildings. The composite profiles are available in sheet thicknesses from 0.75mm to 1.25mm. The maximum available length is 15m.
