Profiled galvanised steel decking is a permanent formwork system
for construction of composite floor slabs. The steel sheet has
surface indentations and deformities to effect a bond with the
concrete topping. The concrete will still require reinforcing with
steel rods or mesh, even though the metal section will contribute
considerably to the tensile strength of the finished slab.
Typical detail †
Where structural support framing is located at the ends of a
section and at intermediate points, studs are through-deck welded
to provide resistance to shear †
There are considerable savings in concrete volume compared with
standard in-situ reinforced concrete floor slabs. This reduction in
concrete also reduces structural load on foundations.
