Lasting legacy, new possibilities

When SBS Group was first founded in 2003, there was a vision: to make the complex simple. Our commitment to ‘construction through innovation’ has meant we’ve always been at the forefront of the industry.

The SBS Group name implies trust and confidence. And at Cortek, the same holds true. It’s a new brand building on our existing solid foundation to offer more value, creativity and possibilities than ever before.

While the Cortek name may be new, it was chosen to reflect our tried, tested and logical approach and our commitment to continual innovation.

Our Process


Every project is unique in design, scope, and detail – allow us to arrange a consultation session to provide value managed solutions tailored to your project needs.


Using the latest 3D computerised software, framing is shop detailed in-house including comprehensive fabrication layout plans and fixing locations. Framing is modelled and engineered to comply with the relevant building codes and certified engineering specifications.


Coordination meetings and communication along with site support form part of our unique customer focused service.Framing is manufactured in a controlled environment from light gauge steel materials using state-of-the-art CNC machinery. Deliveries are coordinated to suit individual project schedules and requirements.

Client Testimonial

“By using Cortek (SBS Group), we estimate that we have saved approximately 2 months of construction programme and associated preliminaries.

Cortek steel framing proved to demonstrate a number of advantages in which were seen throughout the entire build. Onsite, and in comparison, to using conventional concrete structure or timber frames, Cortek provided significant time saving in the project construction. Logistically, Cortek’s coordination of delivering frames and on-site handlings also worked in the projects advantage.

Advantages were not only limited to on-site construction; we found that in the design stage of the project the Cortek shop drawings were able to be coordinated with the likes of windows and joinery shop drawings to eliminate design clashes.”
