Multideck 50-V2 Multideck 50-V2 is a ‘dovetail’ profile deck with a depth of 50mm providing spans up to 4m unpropped. Key benefits include: • Greater Design Efficiency The larger range of Multideck gauge thicknesses allow much closer matching of design requirements and deck performance. • Quicker Installation Contents Specification and Design 9 No temporary supports required under most conditions. A wide range of accessories allows for easy installation of ceilings and services. • Technical Support Load Tables 11 Fire Performance 17 Dramix® Load Tables 20 Kingspan Toolkit software includes comprehensive composite floor design software which allows the user to easily select the right Multideck solution. The design software is available for download from the web site www.kingspanstructural.com. The Multideck design department provides a comprehensive engineering and advisory service to specifiers and end users on the use of the Multideck range of composite decks.

Multideck 50 Multideck 50-V2 Load Tables When using load tables for Multideck 50-V2 please take into consideration the following notes: 1 The table shows the maximum span in meters of the Multideck product for the applied loads and slab depths shown. Values are shown for each gauge where the deck is single span or double spans, plus values for propped spans during construction. 12 Deflection under construction loading (wet concrete etc) has been limited to that stipulated in BS5950 Part 4 1994. At the composite stage the suggested maximum ratio of slab span to slab depth are 35 for NWC and 30...

Multideck 50 Multideck 50-V2 Fire Performance – Mesh 1 The fire resistance tables for Multideck 50-V2 on the following pages are based upon fire test data from full scale tests performed at the Warrington Fire Research Centre UK, May 1998. 2 All stated slab depths comply with the minimum fire insulation criteria of BS 476: Part 20 1987. 3 The composite slab is assumed to be continuous over one or more intermediate supports. i.e. minimum double span. 4 The fire resistance load tables are for continuous spans only with no propping. For propped and single span conditions use the Kingspan Toolkit...
