R.E. McMahon has been delivering complex industrial plumbing solutions across Illawarra, Shoalhaven, and Sydney since 1966. Our clients include BlueScope Steel, BHP/South32, Orica, Sydney Water, and Port Kembla Coal Terminal. We hold an alliance contract with BlueScope Steel that has run continuously since 1995.
We solve industrial plumbing problems. That means identifying the cause, designing a cost-effective solution, fabricating the components, installing and commissioning the system, and maintaining it long-term.
