Embracing light steel framing as alternative to timber

Uncertainty around timber supply for residential construction shows how the fortunes and future of New Zealand’s construction and manufacturing sectors are inextricably linked.

Our residential construction supply chains are not resilient, with an over reliance on one material. Firstly, there are credible and cost-effective alternatives to timber. Light steel frame construction has been available in New Zealand for over 30 years as a viable alternative to light timber frame construction in one to two story housing. Read more

Supply chain performance in CFS house-building*

Prefabrication is gaining greater traction because of its potential to address New Zealand’s housing problem with cost-effective, rapid construction and quality solutions. This has placed huge responsibility on producers (supply chains) as the flagbearers of innovation in construction. However, most of the small and medium sized producers, irrespective to their involvement in the offsite work, are facing critical challenges to remain in this competitive business. 

A list of critical factors was compiled based on the opinion of prefab experts for performance of suppliers in prefabricated house-building (from manufacturer to builders). Later a survey was conducted (pre-COVID), with suppliers of CFS building products (framing to volumetric), to determine the criticality level of performance challenges at company level. This study provides an insight of the CFS industry and vary based on the organizational maturity, supply chain roles and business scope. Also, it is helpful for both existing and prospective suppliers of CFS products, to understand the business dynamics.

*These findings are taken from PhD research project of Mr. Rehan Masood under supervision of Dr. James Lim, from Department of Civil & Environmental Engineering, The University of Auckland, Auckland (




Steel Framing Presentation at UNITEC in Lockdown Level 3

One of the skills that lockdown has taught us to embrace is using technology and the level 3 lockdown in Auckland meant the steel framing presentation to the Architectural Technology student had to be held via a Zoom session. Over 150 students attended the virtual session, it was the largest presentation on steel framing that NASH have given.

The presentation was planned for 3 hours, but over ran by 15 minutes. There were questions at regular intervals throughout the sessions from the students.

The presenters were Alistair Fleming from NASH providing an introduction to steel production and applications.

Daniel Spencer from Framecad gave an in depth presentation on designing with light steel framing and examples of buildings under construction.

Bruce Campbell who is an Architectural Designer who has designed a number of steel framed houses and had a couple steel framed houses built for his own use.

Steve Tsai the lecturer who arranged the session was pleased with the presentation.

We are now looking to next year to improve the coverage and activities for steel framing at UNITEC.




Wintec’s Carpentary Students discover the benefits of Light Steel Framing

 Rollforming Services (RFS) and Central Steel Framing (CSF) teamed up to help Wintec’s (Waikato Institute of Technology) carpentry apprentice students learn how to assemble steel frame walls. Students discovered the benefits of steel framing and the experience opened their eyes to the possibility of working with steel framing in the future. See more




Cold Formed Steel Design Seminar Feb 2020

Cold-formed steel is one of the most vibrant and exciting developments in steel construction, with New Zealand and Australia being amongst the world leading countries in this form of construction. Cold-formed steel is used in New Zealand for portal frame structures, houses and medium rise buildings. The design of cold-formed steel is completely different than hot-rolled steel due to thin section thicknesses and the associated need to consider buckling behaviour.


• Direct Strength Method provided by AS/NZS4600 needs engineering judgments on the buckling behaviour of the elements that will be introduced and discussed in this seminar.
• Direct Strength Method demands computer modelling in THINWALL, CUFSM, or other finite strip method software which will be covered in this seminar.
• There will be worked examples presented during the seminar such that participants will be prepared to use Effective Width method and Direct Strength method with more confidence as soon as they get back to their office.
• Connection designs and their concepts will be discussed in the portal frame and building designs which are useful for practicing engineers.
• New findings in the area of cold formed steel designs will be introduced and discussed.

Seminars are being held all over NZ!
