Questionable steel product conformance hits news headlines

The Ministry of Business Inovation and Employment (MBIE) and Commerce Commission announcement that some concrete reinforcing steel mesh supplied into the New Zealand construction market doesn’t comply with New Zealand standards has caused considerable concern. Resulting in HERA staff recently being the target of extensive media attention with varying degrees of accuracy in being quoted.…

Notice – Design of composite beams with composite slabs using profiled steel decking

Rules for evaluating the design resistance of headed stud connectors through-deck welded within steel decking are provided in NZS 3404.1, 13.3.2.2. Due to the pitch of the ribs in the deck, it is normally not possible to provide enough shear connectors to provide a resistance equivalent to the lesser of: the tensile resistance of the…

Notice – Influence of durable marking methods on the fatigue strength of steel compontents

According to EN 1090-2, steel components have to be identifiable and traceable throughout the whole production chain. The choice of identification method is not specified consistently in international rules and standards. In terms of durability and liability, markings should be resistant to particular fabrication processes such as sandblasting, hot-dip galvanizing or coating. The methods are…
