What is steel decking

‘steel decking’ are sheets of high-performance galvanised steel used to construct floors and roofs in buildings such as offices, apartments, industrial warehouses, supermarkets, schools, hospitals and car parks.

Steel decking is also known as metal deck, corrugated steel sheeting, metal flooring and composite steel decking,steel floor deck.

Steel decking is most commonly used in steel frame construction where is it combined with sheets of steel mesh reinforcement and concrete to provide a cost and time efficient type of composite formwork.

During manufacture, steel decking is shaped into shallow or deep profiles (known as ‘dovetail’ or ‘re-entrant’ and ‘trapezoidal’) and different gauge thicknesses. The required load capacity, span width and fire performance of the finished composite concrete floor dictates the type of steel floor profile specified. It also influences the depth of the reinforced concrete slab cast upon it.
