ROK Slab Supports

ROK hollow core slab (HCS) supports are factory made steel parts designed for support of HCS slab end at holes in HCS slab structure. ROK support transfers HCS slab end support reaction to adjacent HCS slabs or walls in both installation of HCS slabs and in the final situation. ROK support (together with seam grout) acts as support structure until fire resistance class R 60 without separate fire protection. Rok Slab Supports are available with the 40 microns primer painting.
