Building & Housing Minister Nick Smith said yesterday the Government had made changes to testing requirements to ensure all steel mesh being sold in New Zealand is up to standard.
“We’re increasing the number of samples which need to be tested, clarifying how that testing is done and requiring testing be done by internationally accredited testing laboratories,” he said.
The updated verification method & acceptable solution will apply to all steel mesh of grade 500E being sold in New Zealand, whether made locally or imported. The changes will be implemented by 30 May 2017 and follow public consultation after issues with the quality of a small amount of steel mesh, which the Commerce Commission is investigating.
Dr Smith said ductility – the capacity of mesh to keep its strength when stretched – had been causing concern: “The rules were strengthened after the Christchurch earthquakes so steel mesh in all new homes had 10% ductility, to increase the resilience of floor slabs after a quake.”
