  • the present invention relates to galvanized steel deck and a system thereof for use in the construction industry, and in particular but not exclusively, for use in the construction of buildings such as steel frame buildings, concrete frame building and similar building types.
  • Composite construction is widely used in the construction industry due to the benefits it brings.
  • the benefits include structural stability, an increased speed of construction, and savings in weight and size of the primary structure of a building.

Hence, it is essential that such steel decking is carefully designed and constructed. However, during the construction stage in which wet concrete is poured over conventional galvanized steel decking, the steal decks of the decking can easily move apart. Furthermore, temporary propping may also be required during the construction stage.
