R51+ Metal Floor Deck

The original R51 profile has been part of the SMD shallow floor deck suite since the early 1990s, and with improved structural efficiency, the R51+ has taken it's place.

The R51+ offers the same core benefits as its predecessor; excellent slab load carrying capacity, shallow slab depth option (100mm minimum for 1-hour fire rating) and flexibility for shear stud placement due to 150mm trough spacings. However, it now comes in S350 and S450 grades and thicknesses from 0.8mm to 1.2mm.

A traditional re-entrant profile and is commonly used on inner city high Multi-Storey projects where the structural zone is limited, due to the relatively thin slab depth required to achieve a typical one-hour fire rating.

Benefits:
- 102 mm minimum slab depth, whilst still achieving one hour fire rating.
- Wide flat trough provides flexibility for shear stud placement.
- Soffit 'wedge nut' fixings available with load capacity of up to 2 kN.
- With minimal voids in the concrete section allowing dense slabs to be constructed, providing good sound insulation.
- Fire rating up to four hours.
- Acoustic robust solution.

SMD Complete Composite Floor Solution:

SMD can provide a 'one-stop' floor solution providing the decking, shear studs, reinforcement and concrete in one package using dedicated floor laying teams co-ordinated by the same site manager that oversees the decking and shear stud installation. Consult with manufacturer for details.
