Trapezoidal Metal Profile sheets with strong and reliable shear bond performance which is augmented by cross embossing located in the profile. The composite floor profile offers the ultimate in the light weight steel decking which reduced concrete usage to provide a cost effective and alternative floor solution that easy to install.   Application High Rise Buildings Multiplexes / Commercial Buildings Power Plant Buildings Office Buildings Mezzanine Floors in Industrial Buildings & Warehouses Steel deck fo rmezanine floors Thickness 0.8mm/1mm/1.2mm/1.6mm/2mm Technical Specification Base Metal High tensile structural grade steel Coating Mass 120, 180 & 275 GSM Coating Standard IS : 277 Yield Strength 240 MPA Premier Coating Minimum 10 Microns Colour coating Premier 10 Microns Bottom 25 Micron 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. Advantages 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.

The floor is constituted by a profiled sheet onto which a layer of concrete is poured. The sheet is bonded to the concrete by means of mouldings on the sheet which stop the concrete from slipping horizontally and detaching vertically. When the concrete is poured and until it has reached an appropriate level of hardening. (stage 1), the weights of the concrete, personnel working and equipment used in borne by the sheet alone. Once the concrete has hardened . (stage 2) the sheet and the concrete form a unified bond with all the Characteristics of traditional reinforced concrete, where the sheet, after having performed the function of framework, acts as a metal reinforcement. Appropriate crop ends must be provided to absorb the negative moments.

The standard mezzanine system consists of a steel deck support by joists onto main mezzanine beams. If required by design loads, the main beams shall also be supported by intermediate columns. The top flange of the joists fit immediately below the top flange of the primary beams. The embossments on the top and the sides of the ribs provide added grip and minimise slip by creating a bond with concrete as done with normal reinforcement. It provides permanent form work as well as positive reinforcement. No erection, removal, handling or storage of timber / steel form work as in conventional concrete slab construction, saving valuable time. Clean, uniform and attractive ribbed underside for exposed situation reduces the cost of ceiling finishes. MS deck sheet is provided for suitable load on the floor and covered with form concrete.
