1. SMARTDEK 51 Structural Decking System

2. OverviewMenara Imperium, Jakarta, IndonesiaLYSAGHT SMARTDEK 51 Structural Decking System is SMARTDEK 51 is suitable for typical applications as itan innovative high strength zinc-coated steel decking systemprovides widest cover per weight of steel and also minimisesdesigned for use in the construction of composite floor slabs. It isthe requirement for reinforcement. It acts as a permanentspecifically developed for the Indian Construction Industry and isformwork for a composite concrete slab, which in its assembledone of the most economical structural steel decking in the country. state can be used as a working platform as well as a formwork toSMARTDEK 51 system complements the LYSAGHT profiles,support wet concrete, construction materials and trades. Whenwhich is a premium range of roofing and wall cladding solutions.the concrete hardens, it acts as the bottom tensile reinforcement.The high quality LYSAGHT SMARTDEK 51 Structural DeckingSMARTDEK 51 system is a complete structural steel deckingSystem reinforces the principles of trust and reliability that Tata system for concrete, masonry and steel frame construction andBlueScope Steel represents. has an exceptional composite performance.History of LYSAGHT Decking Profile 19641968 1989 1992 19982006 TROFDEKCELDEKBONDEK II W-DEK POWERDEK SMARTDEKTM 512 3. Designed to PerfectionLYSAGHT SMARTDEK 51 Structural Decking System is an SMARTDEK 51 panel has a rib depth of 51 mm and providesinnovative W profile structural steel decking system. It bringsan effective cover width of 960 mm as shown in the figure 1.1.greater economy and design freedom as it is precision engineered Embossments on top of the flange provide excellent mechanicaland provides ease of use as well as safety.
