Material Specification - 350N/mm2 Steel
Steel strip for Multideck 50-V2 complies with BS EN 10143 and BS EN 10147 with a guaranteed minimum yield strength of 350N/mm² and a minimum total coating mass (including both sides) of 275g/m².
Concrete Volumes & Specification
Load/span tables are based on Grade 30 concrete, having a design strength of 30N/mm². Density of normal weight concrete: 2400kg/m³ at wet stage. Density of lightweight concrete: 1900kg/m³ at wet stage.
Reinforcement
Reinforcement of the slab to prevent cracking at all intermediate supports is required in BS 5950: Part 4 1994. Steel reinforcement for anti-crack or fire engineering purposes in accordance with British Standards: Hot rolled bars – BS 4449: 1997; Fabric reinforcement – BS 4483: 1998.
Embossments
Unique combination of embossments on each face of the ‘dovetail’ provide mechanical connection to enhance the bond between the harden concrete and the deck.
