7 OMFLOR OMPOITE TEEL FLOOR DEK omflor THE WORLD FIET OMPOITE TEEL FLOOR DEK omflor, the new generation in composite steel floor decking sstems joins teel & Tube, ew Zealand s leading distributor of steel and stainless steel products and services bringing the world of steel-framed construction closer to ou. ITERATIOAL EXPERTIE, LOAL ERVIE omflor was developed b Tata teel Europe with testing and software development managed b the teel onstruction Institute in the United Kingdom. Local testing in conjunction with HERA has utilized the properties of high-strength steels available in ew Zealand to further strengthen the product range. omflor is now the unrivalled ew Zealand market leader in the design and suppl of composite decks. Our innovative product range and design software enables clients and their professional teams to achieve enhanced project econom, swifter construction and optimised design. Our track record of success has been achieved through our understanding of structural engineering demands and commercial realities. This insight ensures we will continue to lead the industr b providing design options that enable building owners and their advisers to realise even greater levels of project performance and efficienc. APPLIATIO The primar application for omflor is in composite construction, where optimised deck spans and long span composite beams allow architectural freedom. It also helps to reduce the piece count for the whole fabrication and erection process in the structural frame. This is wh omflor is used on prestigious construction projects across ew Zealand in man sectors of the construction industr including offices, hotels, retail centres, hospitals, car parks and warehouses. WHY HOOE OMFLOR PERFORMAE: omflor provides a bracing diaphram for the structural steel during construction, eliminating dedicated bracing elements required for pre-cast construction. IMPLIITY: omflor 60 and 80 doesn t need temporar propping and can be manhandled into position for stud welding ver quickl, saving time and mone. (ource: Z magazine) OT EFFIIEY: The speed of installing omflor can reduce the construction cost. UTAIABILITY: omflor is full recclable at the end of the building s life and utilises up to 2% reccled steel during manufacture. 3 PROFILE AVAILABLE - OMFLOR 60 & 80 ARE DEIGED TO OPTIMIE U-PROPPED OTRUTIO omflor allows for optimisation of the supporting steel and is an enabler for efficient building design. Tpicall the structural steel contract cost is 4.5 to 5 times the value of the installed omflor. The installed omflor package is tpicall onl.25% of total building cost. Thus the wider contribution omflor makes to the project far outweighs its cost.

8 OMFLOR OMPOITE TEEL FLOOR DEK (OTIUED) omflor EIMI PERFORMAE In hristchurch the HB Tower and the Pacific Tower provide a model for the rebuild. The have survived the earthquakes with minimal damage and the lessons learned will reduce damage further on new builds. As an eample, Z have developed standard details for Removable Links in Eccentric Braced Frames (EBFs). omflor was the enabler for efficient design that won these projects for steel framed construction in a market dominated b precast concrete construction. OMFLOR AD TEEL FRAME PROVIDE TEMPORARY WORK TABILITY This is an important consideration in hristchurch during the initial stages of the build program. tabilit is improved as each phase of the building structure is assembled primar beams secondar beams the omflor the shear studs and the concrete slab. LOG PA BEAM OPTIO This allows epansive, column-free floor plans. There are now long span steel solutions ranging to 5m - with full design support from FABE and ellbeam. omflor is in their libraries. These are UK based sstems with licence agreements in ew Zealand. VIBRATIO AALYI There is ecellent vibration analsis available through Z. Eperience indicates 4m spans are less problematic than 9m spans. EW ZEALAD MAUFATURED AD UPPORTED teel & Tube manufactures omflor in East Tamaki, Auckland. We are proud to bu ew Zealand made and sourced steel coil from ew Zealand teel. ew Zealand teel utilizes both local black sands and 2% reccled steel in the manufacture of the raw steel used in our profiles. We offer design support and are keen to be involved at an earl stage. We provide software to design the omflor slab and OBEZ is available to design the composite beams. Z also offers a preliminar design service. In addition to our strong research, manufacturing and distribution epertise we retain a ver eperienced omflor team who are here to advise architects, specifiers, construction companies, engineers and quantit surveors. This support includes help on how to use the omflor software, the engineering behind it and information regarding suppl and installation. We aim to support our customers b being available when needed, as well as eposing them to the latest thinking in steel construction.
