The Hambro composite floor system consists of open web steel joist with a top chord embedded in a reinforced concrete slab. The combination of the joist and the slab performs as a “T” shaped beam. The concrete slab is reinforced with welded wire mesh and behaves structurally as a continuous one-way slab orientated perpendicularly to the joists.
