Tray-dec 80 is a trapezoidal style of steel 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.
