Tray-dec 80

Tray-dec 80 is a trapezoidal style of composite flooring and the strongest Tray-dec profile. This profile allows for longer spans and thicker slabs, maximising strength and fire ratings. Longer spans minimise the requirements for support beams. The minimum slab thickness is 130mm using Tray-dec 80.Designs are in accordance with AS/NZS 2327:2017

Design
Adjacent sheets are joined along the overlapping edge using self-tapping screws. The inverted (rather than reentrant) top rib maximises concrete cover for a given slab thickness and increases strength in composite action.

Quality Materials
All Tray-dec 80 is rolled from high strength zinc-coated steel coil in compliance with AS 1397-2011. Tray-dec 80 profiles are made from grade G500 steel and are available in either 0.95mm or 1.2mm thickness. Construction and composite span tables are provided for each grade.

Longer Spans
Multi-span trays are able to span up to 4.9 metres unpropped and over 8 metres propped depending on slab thickness. Longer spans require less support beams and allow larger beam spacing. Nelson Shear Stud Placement Symmetrical interlocking trays allow for simple and even placement of Nelson shear studs. Studs welded through deck optimise composite properties of the slab.

Accessories
Accessories to complete necessary formwork include internal and external end caps, folded metal edge form to suit the slab thickness and closure plates.
