Our profiles are available in three thicknesses; 0.75mm and 0.95mm for Tray-dec 60 and Tray-dec 300, and 0.95mm and 1.2mm for Tray-dec 80. The minimum yield strengths for each thickness are: 550 MPa for 0.75mm and 0.95mm, and 500 Mpa for 1.2mm. Tray-dec products can be supplied in any length, subject to the limitations of available transport and safe manual handling.
Tray-dec 80 is a trapezoidal style of composite flooring and the strongest of all Tray-dec profiles. This profile allows for longer spans and thicker slabs, maximizing strength and fire ratings.
Unpropped spans range up to 4.8 meters and over 8 meters when propped. Longer spans require fewer support beams and allow larger beam spacing. The design includes pre-punched holes along the joining ribs. The sheets lock together with metal fasteners every 600mm. The inverted top rib allows for maximum concrete cover, increasing strength in composite action.
Tray-dec 60 is an intermediate decking solution with mid-range spanning capabilities. It is lighter and a lower cost than larger profiled composite decking.
Both Tray-dec 60 and 80 have symmetrical trays that allow for simple and even placement of shear studs. Studs welded through deck optimise composite properties of the concrete slab.
Tray-dec 300 is a flat soffit composite deck which interlocks with adjacent trays to act as tensile reinforcement and permanent formwork.
The flat soffit allows for a uniform slab thickness. Tray-dec 300 is ideal for buildings constructed of steel, concrete or masonry. Self-locking sheets interlock and snap in place and require no fasteners.
