About BONDEK® IIStructural Decking Profile

Features and Benefits of BONDEK® II Profile Why Choose BONDEK® II Profile

LYSAGHT BONDEK® II profile is widely accepted by the building construction industry to behighly efficient, versatile and robust. It has also been used to great effect on many majorbuilding projects, as well as countless small ones.

BONDEK® II steel profile has been developed from the original BONDEK® profiled steel sheeting.It has a similar profile shape but a significantly more effective longitudinal tensile reinforcement.The top of the ribs has been embossed to bring about greater mechanical bonding betweenthe steel sheet and concrete. Its higher yield strength and larger effective depth makes it moreeffective than the same area of deformed bars or welded wire fabric.

BONDEK® II steel sheets are permanent formwork for a suspended composite concrete slab. Inits assembled state, it can be used as a working platform and formwork to support wet concrete,construction materials and trades. When the concrete hardens, BONDEK® II acts as the bottomreinforcement of the concrete slab.

BONDEK® II is a complete structural steel decking system for concrete, masonry or steel frameconstruction.

BONDEK® II Profile and Dimensions

The nominal dimensions of BONDEK® II profiled steel sheeting are shown in the figure below.The effective cover width is 600mm. In the assembled state, the profile comprises twointermediate dovetail ribs for every interlocking side-lap joint. The assembled ribs are all boldlyembossed along their exposed top faces.

1. Research & Development SupportBlueScope Lysaght places great emphasis on product research and testing. All of ourLYSAGHT® structural products are subjected to rigorous tests such as slip block test,formwork tests including shear and bearing, full scale slab test, composite slab cyclic test,fire rating test, formwork – air pressure test, formwork – four point load test and concentratedload test. These tests are carried out in the labs of the Lysaght Technology Centre inChester Hill, Sydney, Australia, to ensure maximum performance and quality of our decking profiles.

2. Improved Fire PerformanceBONDEK® II profiled steel sheeting has been put through further fire tests conducted atthe Victoria University of Technology to ascertain the contribution of BONDEK® II decksto the positive moment capacity of a composite slab in fire. The structural adequacy of thecomposite slabs and its resistance of significant tensile forces in bending, in addition tothe conventional reinforcement, have been established.

3. Accreditation by NATA LaboratoriesOur test results are accredited by NATA Laboratories to facilitate product listing schemesof local authorities.

4. Product Recommendation & Design to Suit your SpecificationsWorking from your project specifications, our engineers will follow-up on your requirementsand work out a set of calculations and a project proposal. A user-friendly Excel-basedsoftware for the design of composite slabs with LYSAGHT BONDEK® II profile is availableto assist a competent engineer in deriving an optimal solution. This software should beused in conjunction with the BONDEK® II Design and Construction Guide.

5. Quality Assurance – Material & Manufacturing ProcessThe LYSAGHT® brand name is synonymous with quality and performance. As with all otherLYSAGHT® products, BONDEK® II profiled steel sheets comply with major design standardsadopted across Asia.
