Steel Decking

RMI Steel Deck is a new innovative profiled steel decking which brings greater economy and design freedom to building with composite concrete slabs. Our design engineers scoured the globe to find the best “W”- profiles in the world.

RMI structural decking system is an innovative high strength Zinc-coated steel decking system designed for use in the construction of composite floor slabs. It is specially developed for the Sri Lankan construction industry and is one of the most economical structural decking in the country. It acts as a permanent formwork for composite concrete slab, which in it’s assemble state can be used as a working platform as well as a formwork to support wet concrete, contraction material and trades. when the concrete hardens, it acts as the bottom tensile reinforcement.

Key Advantages

  • Spanning Capacities: It has good spanning capacities. 1.0 mm BM Steel Deck can span more than 3 metres unpropped.
  • Composite Action: The composite action of a composite slab depends on a complex interaction between steel sheeting and the surrounding concrete and is the key factor of determining the behaviour of the composite slab. Experiments indicate that longitudinal shear transfer mechanism (composite action) is provided by mechanical interlock between deck and concrete.
  • Design Efficiency: The thickness of our varies from 0.75 to 1.0 mm BMT and its grades of steel varies from 300 MPa to 550 MPa.
  • Design for Fire: Roofmart Steel Decking composite slabs can be designed for up to 4 hours of fire rating.
  • Quicker Trouble-Free Installation: Ideal for quick and easy installation. It is available in long lengths so large areas can be quickly and easily covered to form a safe working platform during construction. Roofmart Steel deck provides a cover width of nominal 950 mm.
