Downstand beams are incorporated in the coffer system thus making for quick and easy erection Coffer or trough floors give a reduction in concrete and reinforcing steel The slab is lighter, resulting in a reduction in weight of foundations and support Coffers and troughs can be used on the standard Uni-Stage support system They can be kwikstripped thereby effecting a substantial saving in the number of coffers and troughs required The steel or fibreglass units are light and easy to handle Coffer or waler slabs are used to construct large twoway spanning floors. The coffers can be used in conjunction with standard kwikstrip beam and decking plates for the flat areas and can be "kwikstripped" by releasing the doubleheaded jack leaving the Uni-Stage support in place.
