2.2 - Floor deck material specification

SMD floor deck products are typically used as part of a composite floor slab (with the exception of TR50), with the deck acting as both permanent formwork and tensile reinforcement (sagging) in the bottom of the slab, designed in accordance with

• BS EN 1993-1-3

• BS EN 1994-1-1 or BS5950: Parts 4 & 6.

Alternatively, the floor deck may be used as permanent formwork only. In this situation, the deck forms the concrete, with reinforcement required to support the specified imposed loads designed by the project structural engineer, ignoring any contribution from the metal deck.

SMD floor deck profiles are manufactured from steel strip in compliance with BS EN 10143 & BS EN 10346. Products are available in minimum yield strengths from 250 (S250) to 450N/mm² (S450) with a typical minimum coating mass of 275g/m² (Z) coating (0.02mm per side) or 120g/m² (ZM) in accordance with BS EN 10326, depending on product selected.
