BRANZ research is filling the knowledge gap in how geothermal corrosion affects typical building materials. This will lead to guidance for the design, construction and maintenance of buildings in geothermal areas.
By Zhengwei Li – 1 April 2018, Build 165
BRANZ research into material corrosion rates in various positions on a building envelope has made a surprising discovery that will help in material specification and maintenance.
By Trevor Pringle – 1 February 2007, Build 98
In the fight against corrosion, hot-dip galvanising can be a useful tool.
By Zhengwei Li – 1 October 2017, Build 162, Feature article
BRANZ has been investigating what can make metal fasteners and fixings corrode when used in timber. Understanding this can lead to selection of compatible components and less risk of premature failures.
By Zhengwei Li – 1 August 2009, Build 113, Feature article
Although timber treatments protect timber, they can corrode nails, screws and other hardware used in building. A BRANZ research project is investigating the effects of different treatments on some common types of metal fasteners.

Avoiding corrosion of fasteners requires careful detailing to ensure detrimental chemical reactions do not occur, which can reduce the life of the fastener.

BRANZ’s timber structures durability work has seen sawn sapwood and heartwood timber exposed to the weather in various locations. The next stage is applying knowledge gained to engineered wood-based materials.
By Zhengwei Li – 1 February 2021, Build 182, Feature article
BRANZ research is expanding our knowledge of how multiple factors influence building material corrosion. This will lead to a new way of mapping corrosivity and allow the right materials to be specified for different environments.
