What lies beneath – Tray-dec floor system

Part of the major refurbishment of the ANZ Centre, the street-level ANZ meeting suite incorporates attractive stone flooring. Providing a stable, solid subsurface is a contemporary composite floor system specified by architects Warren and Mahoney.

Tray-dec provided the steel floor profiles for the metal and concrete floor. General manager Mike Smart says the system offers a highly stable and economical alternative to other types of suspended floors.

"As a flooring option, Tray-dec is particularly well suited to steel beam structures, such as the ANZ Centre. The product, which looks somewhat like corrugated iron sheeting, was used for the floor of the meeting suite and on another section of flooring two levels higher up in the tower.

"After the steel profiles were tied to the structural supports, Nelson shear studs were welded to the steel beams by our sister company, Nelson Stud Welding. The concrete was poured into the Tray-dec to cover the Nelson shear studs, which resemble threadless, oversized bolts, anchoring the concrete to the steel beams," says Smart.

"All steel sections were designed to interlock with adjacent trays, both as tensile reinforcement and permanent formwork for the concrete floor poured on top. The composite action of the steel and concrete creates a floor which is very strong but also light in weight. The system is simple and fast to install, and because the metal sheets are easier to handle, craneage time is reduced."
