Product overview
Form deck is a shallow corrugated steel sheet used as a permanent form for a concrete slab that is reinforced and designed on its own. The 9/16″ deep profile has 3″ corrugations with a 30″ or 36″ cover, in 26 to 22 ga. It spans between joists or beams, holds the wet concrete and construction loads, and stays in place under the finished slab, for example on mezzanines and floors over steel joists. Spans, shoring and slab design are set by the structural designer. Data sheet DS-29 shows the profile, slab sections, shoring guidance and accessories.
