Mezzanine projects are designed to AS4600, giving builders and project teams confidence throughout the build.

Panelised Steel Floor Systems

Newcastle Steel Frames engineered steel floors can be panelised and built off-site, then delivered to your project and installed quickly. This helps save valuable time, reduce site waste, and lower the risks that come with extended on-site work.


This off-site construction method is becoming increasingly popular with project builders, commercial builders, and medium-density developments. It allows projects to move forward with fewer delays caused by weather, site access issues, or material waste, while also making installation easier on tight or difficult worksites.


Our panelised steel floor systems are manufactured from DWG/CAD files in a controlled factory environment. Once complete, delivery is arranged and the floor system can be installed using a mobile crane or crane truck. This allows the floor structure to be installed in minutes, rather than taking hours or days on site.
