For more than 50 years, Balcombe Engineering Pty Ltd has held the top position in Australia as a specialist maker of flanges, spectacle blinders, and tubeplates/tubesheets for the petrochemical, general industrial, and food sectors. The widest selection of flanges and valves available in Australia as well as an extensive in-house production facility are both found at the Melbourne site, which is situated in Hallam. Vast inventories and in-house production allow Balcombe to produce any needed flange, spectacle blind, or valve in a matter of hours (if it is in stock) or between the following day and two weeks (if it needs to be specially made).

The business is located in a nearly 6000 sq. m. purpose-built structure. This Melbourne complex is about one minute's walk from Hallam.
