Tray-dec 300

Tray-dec 300 is a flat soffit composite deck where adjacent trays interlock to act as both tensile reinforcement and permanent formwork for a complete concrete floor slab.

Designs are in accordance with AS/NZS 2327:2017

Design
Tray-dec 300 has a profile with a flat soffit allowing uniform slab thickness and can be used for buildings constructed of steel, concrete or masonry. The uniform slab thickness results in optimal acoustic performance. No end closures are required, and sheets interlock without the use of fasteners, crimping, drilling or riveting.

Nelson Shear Stud Placement
Self-locking trays spaced every 300mm makes Nelson shear stud installation convenient. Studs welded through deck optimise composite properties of the slab.

Quality Materials
All Tray-dec 300 is rolled from high strength zinccoated steel coil in compliance with AS 1397-2011. Tray-dec 300 profiles are made from grade G500 steel and are available in either 0.75mm or 0.95mm thickness. Construction and composite span tables are provided for each grade.

Accessories
Because of the flat underside of the profile, Tray-dec 300 does not require end caps to prevent concrete spillage. Folded metal edge form is manufactured to suit slab thickness.
