Call for attendees – #MIC2017: delivering the goods on options for conformity

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…

A major milestone struck in our seismic testing on stainless

We’re pleased to announce that the first test on stainless steel connection was successfully performed 28 July 2017 at the University of Auckland’s testing lab. Answering what we believe is a growing industry necessity to understand the behaviour of structural stainless steel connections under severe seismic load. For HERA it’s an area where we currently…

Resource – Adding boron to structural steel for export subsidies

Historically, boron has not been intentionally added to structural steel manufactured in New Zealand or Australia to AS or AS/NZS standards. However some overseas steelmakers have added boron to structural steel to take advantage of export subsidies or for other reasons, including improved impact energy. Reports indicated that some imported steel may show elevated levels…

Seismic testing gives stainless the design freedom of carbon steel

Even though stainless steel structural sections have been available since the 1960s, the industry hasn’t shown great interest until the last decade – the main reasons being a lack of material knowledge, limited supply sources, irregular demand, small volumes, long delivery times and high prices. Today this has changed, with the market not only asking…
