ACS developed Combination Edge Trim (CET) for use with steel frame structures. It acts as a permanent shuttering when pouring concrete in-situ onto ribbed decking floors.
Cast into concrete
The main advantage of this system is that the profiled trim incorporates a channel for casting into the concrete. In contrast fixing to the face of thin slabs with site drilled bolts can become impractical or very expensive. Especially when trying to transfer loads from masonry support angles, curtain walling or even Add to dictionary back into the structure.
