Wall frames

The quality design, efficiency and reliability of prefabricated BlueScope TRUECORE® steel wall frames by Dahlsens save you time in the framing stage to reduce the overall build time.

Cost Competitiveness

Our steel frames are designed to your requested specifications and delivered direct to your site, reducing build times and labour costs. The Scottsdale Construction Systems design and engineering software used by our experienced design team allows us to optimise components, loading requirements and reduce wastage compared to onsite stick built alternatives.

Engineered Design

The Scottsdale specialised software ensures our steel frames are manufactured precisely and meet or exceed all relevant Australian design codes, including bracing. This allows for the use of in-wall K Bracing to provide sufficient bracing to suit today’s architectural trend for short wall lengths due to large windows and open-plan living.

Walls are available in 70mm, 90mm and 140mm widths. Any shape of wall such as a raked wall can be manufactured, and notches for services such as commercial HVAC can be embedded in the design.

Designs are independently certified by a qualified engineer with a Regulation 126 certification provided.


As the Dahlsens’ steel wall frames are lightweight, easy to handle, and come with pre-installed service holes to facilitate fast installation. Further efficiencies are achieved by the perfectly straight, square, and plaster and cladding ready frames.

Visualise your 2D plan in 3D!

Dahlsens’ 3D View steel framing program, SketchFab, is accessed via a QR Code that appears on your truss and frame manufactured plans to make it easy to understand the structure in the context of the surrounding space. In addition, 3D View gives you the following:

  • A real 3D view of the finished project before lifting a finger
  • The 3D model enables all stakeholders such as the builder, engineer, owner, and architect to get a good understanding of how things will be laid out
  • The 3D model can be rotated for different perspectives and to gather additional views

The 3D view can be used before, during and after installation of your frame, floor or truss to give you a better picture of how to start, key intersections and as a checking tool.

Ask for Dahlsens 3D View to be included on your next layout.
