Sonnex

What Sonnex does

Sonnex Pty Ltd is an Australian privately-held precision manufacturing company headquartered at a purpose-built 2,400 square metre factory in Elizabeth South, South Australia, with over 30 years of operating experience. The company delivers engineering, sheetmetal fabrication, profile cutting (laser and plasma), and custom-built trailer manufacturing services to enterprise clients across six vertical industries: Defence, Mining, Agriculture, Power, Transport, and Space.

Its core production capability is built around advanced manufacturing equipment, including Amada CO2 laser cutting machines with rotary index capability for processing pipes, tubes, RHS, SHS, angles, and channels, complemented by state-of-the-art bending machinery and design/fabrication software. Sonnex generates revenue through project-based quoting, with customers submitting specifications (quantity, material grade, thickness, timeline) and receiving custom quotations; payment is processed via credit card or EFTPOS with no delivery service offered. The company serves enterprise customers directly, with a publicly visible portfolio that includes SAGE Automation, Seeley International, Grundfos, Hardi, Rocla, Engie Axima, Flinders Port Holdings, and other industrial firms.

The business has expanded its footprint via the acquisition of trailer builder RLB Enterprises, joined the Edinburgh Industry Alliance to access sovereign industrial supply chain opportunities, and secured a $1.6 million contract to manufacture components for the Matilda Hub driverless technology trial funded partly by the South Australian government's Future Mobility Lab Fund. Operations remain concentrated in South Australia with no international footprint disclosed, and the company continues to invest in workforce development through its apprenticeship program.

Core offering

Sonnex is an Australian owned and operated precision manufacturing company providing engineering, sheetmetal fabrication, profile cutting (laser and plasma), and custom-built trailer manufacturing services. The company operates from a 2,400 sqm purpose-built factory in Elizabeth South, South Australia, equipped with Amada CO2 laser cutting machines with rotary index and state-of-the-art bending machinery, serving industrial clients across Defence, Mining, Agriculture, Power, Transport, and Space verticals.

Product overview

Sonnex offers precision manufacturing services as a unified portfolio of capabilities rather than discrete software products. The core offering consists of four integrated manufacturing services: Engineering (fabrication and plant equipment), Sheetmetal (bending and forming), Profile Cutting (laser and plasma cutting), and Custom-Built Trailers (acquired through RLB Enterprises). These services work together to deliver complete manufacturing solutions for industrial clients across Defence, Mining, Agriculture, Power, Transport, and Space industries. The company also showcases specific projects like the Matilda Hub for SAGE Automation that demonstrate integrated capability delivery.
