Alter Steel advances Pinkenba steel mill toward Final Investment Decision with Hatch

April 07, 2026

Alter Steel has executed an expanded scope of work with global engineering firm Hatch to finalise development of its proposed Pinkenba steel mill in Queensland, marking a clear step toward a Final Investment Decision (FID) in the coming months, as focus increases on domestic, low-emissions steelmaking capability in Australia. 

Building on more than two years of development alongside Hatch and a group of publicly announced partners, this engagement advances detailed engineering, approvals and construction planning, positioning the project for construction. 

Hatch will continue as Alter Steel’s engineering partner, leading this phase across engineering and project execution, with a focus on buildability and cost optimisation through detailed design and planning, drawing on its global experience across steel and metals projects. 

The Pinkenba steel mill builds on an established reinforcing steel supply chain, with downstream operations already supplying steel across Queensland and nationally. 

The project integrates scrap supply, proven steelmaking technology and downstream processing, including a collaboration with Sims Metal, alongside Danieli and related downstream operations through Bestbar and Wire Industries, creating an integrated pathway from raw material to end-use demand. 
 
This development is underpinned by hands-on experience across steelmaking and downstream processing, with senior leadership each bringing over 30 years of experience operating steel mills and delivering steel into fabrication and construction at scale. 

With established offtake, secured supply partners and detailed engineering underway, the project is progressing through its final development milestones toward FID and remains on track for construction. 
 
Hatch will continue working alongside key technical partners, including steelmaking technology provider Danieli.

 

“This next phase advances the detailed engineering, approvals and construction planning required to take the project through to Final Investment Decision in the coming months. Our approach has been to build the project around a fully integrated supply chain, linking scrap, steelmaking and downstream demand, which is critical to delivering a project of this scale. With Hatch leading engineering and project delivery, we are moving through the final development milestones toward construction.” - Grant Johnston, Managing Director (Alter Steel)

 

 

“Hatch is esteemed to continue working with Alter Steel in advancing the Pinkenba Mill project from a professional services capacity. This project represents an excellent opportunity for Australia to produce low carbon embodied reinforcing steel products given its strategic location and access to supporting infrastructure and services.” - Joe Petrolito, Managing Director for Ferrous Metals (Hatch)

About Alter Steel (www.altersteel.com.au) 

Alter Steel is developing a low-emissions steel mill in Pinkenba, Queensland, designed to supply reinforcing steel to the local market. The project utilises Electric Arc Furnace (EAF) technology and locally sourced scrap, supported by an integrated supply chain linking recycling, steelmaking and downstream processing. 

With a capacity of up to 500,000 tonnes per annum, the project is positioned to support Queensland’s infrastructure and construction pipeline while strengthening local manufacturing capability.
