Mezzanines Floor Systems
Looking for some extra space in your office or warehouse?
Newcastle Steel Frames & Trusses can design, supply and support engineered steel mezzanine floor systems for commercial, industrial and warehouse projects. Built with precision steel framing, our mezzanine systems help businesses increase storage, workspace or operational capacity without the cost and disruption of relocating or major structural expansion.
Extra space without moving facilities
A mezzanine floor is a practical way to turn unused overhead space into a valuable work or storage area.
Fitted within your existing building structure, it helps increase usable capacity without the disruption of new construction or relocating to a larger facility.
For builders, developers and project teams, a steel mezzanine system is a strong, efficient and cost-effective way to add space to commercial and industrial environments.

Design and Engineering
Our mezzanine floor systems are fully engineered floor systems designed to suit project requirements.
Each floor system is developed using integrated design software and supported with structural design certification and documentation.
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.
