The publication of AS/NZS ISO 9606.1:2017 Qualification testing of welders – Fusion welding – Part 1: Steels is seen as a move towards international best practice. And is a standard of significance, because it forms the basis of the next revision of AS/NZS 2980 expected to be published late February. For the many users of…
When steel merchants aren’t able to supply parent materials to a preferred AS or AS/NZS specification fabricators will face the need to weld structural steel manufactured to an overseas standard. This steel is often referred to as “alternative” steel or “not-prequalified” as it isn’t referenced in the welding standard AS/NZS 1554.1. While the standard allows…
AS/NZS 2980, our most widely used welder qualification standard, is up for revision. The draft for public comment can be accessed at the Standards NZ website. The draft is reflects the inevitable process of moving away from local standards to the ISO standards; in this case to ISO 9606-1:2012, Approval testing of welders—Fusion welding, Part…
The Ministry of Business, Innovation and Employment (MBIE) is proposing several amendments to B1/VM1, and it’s important that you have your say in these changes as they’ll affect our steel industry. They intend to: Update Verification Method for B1 Structure (B1/VM1) to cite the latest version of NZS 3101:2006 Concrete Structures Standard: Part 1 – The…
In August 2017, a SCNZ-led standard development committee, which HERA also takes part in, was established to develop a new technical specification for steel corrosion protection. Superseding NZS 3404.1:2009 Chapter 5 Corrosion Protection, the new stand-alone technical specification SNZ TS 3404:2017 Durability requirements for steel structures and components will be developed into a document that keeps abreast…
The factor of safety (FoS), also known as (and used interchangeably with) safety factor (SF), is the ratio between the nominal and the design load carrying capacity of a structural member or system. The factor of safety ensures that the probability of the actual resistance falling below the design resistance is sufficiently low. The magnitude…

Our General Manager Structural Systems heads to Wyoming USA from 30 July to 2 August where he’ll present at the 8th International Conference on Composite Construction in Steel and Concrete. Organized by Virginia Tech, and sponsored by both the American Society of Steel Construction (AISC) and the American Society of Civil Engineers (ASCE) Structural…
Structural steel hollow sections can be well suited to structural applications because they have a higher strength to weight ratio than open section profiles such as “I” beams and columns, channels or angles, and a lower area to be covered by a protective coating. Although they are more expensive than open section profiles on a…
