Mining & Infrastructure

Australia's mining projects and civil infrastructure sectors generate some of the most sustained steel procurement demand in the region. The projects are large, often located in remote areas, and the variety of structural steel required—from processing plant structures and tailings pipeline systems to port piling and marine infrastructure—demands a supply partner with genuine capability across multiple product categories and the logistics experience to deliver reliably to any project site. 

STS supplies specialist steel to mining and resources projects as well as major civil infrastructure programmes across Australia, combining global sourcing with project management capability to deliver complex, multi-product packages on time and to specification.

Australia's ports, jetties, and marine facilities represent a significant and growing market for steel procurement, driven by expansions in resource export capacity, investments in civil infrastructure for defence facilities, and coastal infrastructure renewal programmes across the country. 

Marine structural steel is a specialized category where product knowledge is as crucial as price. Selecting the right grade, wall thickness, interlock specification, and corrosion protection for the service environment is critical, particularly in the context of marine infrastructure. STS brings genuine technical depth to this area, built through years of supplying piling and marine structural packages to Australian port and marine projects, including those related to mining projects. 

We supply complete piling and marine structural packages, consolidating all primary and secondary structural components under a single supply arrangement while managing the documentation requirements of major port and marine project quality systems.

Key products:

- Pipe piles and sheet piles in marine-appropriate grades and wall thicknesses

- Combi-wall systems for quay walls and port retaining structures

- Pile shoes, shear keys, interlocks, and tie rods

- Pontoon steel, gangway structures, and marine ancillaries

Major mining projects — including iron ore, lithium, copper, gold, and critical minerals — require steel across almost every phase of development, impacting both civil infrastructure and marine infrastructure. Processing plant structures, tailings and process pipelines, pressure vessels, materials handling systems, and site infrastructure all present distinct steel procurement challenges, often with specification requirements that exceed what is available in the Australian domestic market.

STS collaborates with mining EPCs, project owners, and fabricators to build supply solutions that are compliant, cost-competitive, and deliverable within the project's schedule. When multiple categories of structural steel are required, we consolidate supply under a single package arrangement, reducing procurement overhead, simplifying documentation management, and lowering freight costs by combining shipments.

Remote delivery is something we manage as a matter of course. Coordinating international freight, customs clearance, and final delivery to remote project sites requires exactly the kind of active logistics management that sits at the core of the STS service model.

Key products:

High-yield and wear-resistant line pipe for tailings and slurry pipelines

Process pipe, fittings, and flanges for mineral processing systems

Pressure vessel plate for autoclaves, leach tanks, and processing vessels

Structural plate, sections, and hollow sections for processing plant and materials handling structures

Major road, rail, bridge, and public infrastructure programmes create sustained demand for structural steel across a wide range of grades and product forms. STS supplies structural steel to civil infrastructure projects, including those related to marine infrastructure and mining projects, where specification, volume, or schedule requirements make international sourcing the right solution. We bring the same supply chain management and documentation rigor to these projects as we do for our energy and resources clients.

Key products:

High-yield structural plate and sections for bridge and heavy civil structures

Structural hollow sections for secondary and architectural structural applications

Global sourcing for steel grades that are unavailable or uncompetitive in the Australian domestic market is essential for civil infrastructure and marine infrastructure projects. We offer consolidated multi-product packages that reduce procurement and logistics overhead, particularly beneficial for mining projects. Our remote delivery management spans across Western Australia, Queensland, and the Northern Territory, ensuring efficiency. We possess technical knowledge of marine and piling specifications relevant to port and coastal projects. Additionally, we provide a single point of accountability across complex, multi-category supply programmes, including structural steel procurement. Full documentation management is also available to meet the quality systems required for major projects.
