OBA (formerly O'Brien-AIM) is the largest supplier of electrical and thermal insulating materials in Australia and New Zealand.
This was not always the case. In fact for most of the 20th
century O.H.O'Brien and Australian Isola Materials were
strong competitors, operating in close proximity, and
servicing many of the same clients.
All of that changed in 2005 when Transmission Australia purchased both companies and merged them as O'Brien-AIM. With a strong, focused management, an injection of capital, and a powerful marketing strategy, the new company has emerged as an industry leader.
The re-branding and name change to OBA reflects this new commercial reality.
OBA's strength is the result of professional and enthusiastic staff, an expanded product range (many internationally recognised brands are exclusive to OBA), and an exceptional level of service.
Today, OBA is setting the agenda and we are pleased to provide you with our story: literally a work in progress.
