Decking Sheet

Composite Decking Sheet

In our Composite Decking Sheet the floor is constituted by a profiled Deck sheet made of metal onto which a layer of concrete is poured. The GI decking sheet is attached to the concrete by method for mouldings on the sheet which prevent the cement from slipping on a level plane and disconnecting vertically. At the point when the concrete is spilled and until it has arrived at a proper level of solidifying, the weights of the concrete, staff working and supplies utilized as a part of borne by the sheet alone. When the cement has solidified the sheet and the concrete structure a bound together bond.

Non-Composite Decking Sheet

Permanent Formwork Profile Range

We manufacture profiles which are used as permanent formwork. Permanent formwork remains it situ for the life of the building but, unlike composite flooring profiles, it does not Act as reinforcement in the concrete slab.

  • The steel decking supports the wet concrete and construction loads.
  • Temporary propping can be eliminated.
  • The concrete slab requires full structural bar or mesh reinforcement.

 Available Finish

  • Cold Rolled (CR) l Galvanised l Both side primer coated (Galvanised)
  • Pre coated galvanised under side giving durable and attractive appearance and minimum future maintenance.


  • Reduced Concrete usage: Tensile steel for composite slab construction that cuts down on slab thickness and dead weight of buildings. Providing a more sustainable solution and reducing costs.
  • No separate formwork required for slab casting.
  • Reduces construction time.
  • Technical department at Alfa offers comprahas sive advisory of service on design of composite flooring should quiries arise which are not cover by this literature please contact us.

Load Tables

  • The structural adequacy of DECK sections is established by choosing the section to provide requisite sectional modules to satisfy moment and deflection criterion. A moment coefficient of 1/8 is used for single and dual spans and 1/10 for 3 or more spans. The deflection co-efficient are 0.013 for single span and 0.0078 for multi spans. The maximum deflection of the DECKSHEETS is restricted to L/250 under uniformly distributed loads.

Benefits Of Metal Decking

  • Light weight. Doesn't require any support, which considerably reduces the use of concrete & slab thickness.
  • Acts as composite member and as permanent shuttering.
  • No major reinforcement required.
  • Deck can be used as a working platform during construction.
  • Speedy construction enables faster completion of a project.Decking reduces the construction time, hence the total cost.
