McMahon Metal Fabricators, founded in 1980 has grown to become one of Adelaide’s most highly-regarded steel fabrication suppliers.

McMahon Metal Fabricators is committed to exceeding our customer’s needs and expectations by following our in house Quality Management System. We have systems in place to capture, record and meet our client’s requirements in conjunction with monitoring and continuously improving our performance.

With over 100 years of metal industry experience, the team at McMahon Metal Fabricators understands the importance of remaining flexible and responding quickly to ensure that critical deadlines are met. We have a proven track record of delivering high quality turnkey finished products on time and on budget.

While McMahon Metal Fabricators supplies “off the shelf” materials in steel and other metals through our SteelPlus division, our real expertise is in providing a wide range of engineering and manufacturing solutions and fabricating custom-made work – either for one-off projects or in quantities for ongoing demand. Our team consists of experienced, energetic individuals who work together to share knowledge and support each other in providing excellent products and services.

McMahon Metal Fabricators is part of the six company STÄRKE-AMG Alliance. All companies in the STÄRKE-AMG Alliance strive to be leaders in the areas that they specialise in, and McMahon is no different.
