How we're making an impact

Circular steel manufacturing

We recycle scrap steel and transform it into new steel products through a continuous circular process. Keeping materials in use reduces waste and supports resource efficiency.

Renewable energy transition

We're increasing the use of renewable electricity across our operations as part of our decarbonisation pathway. This helps reduce emissions associated with steel production.

Lower embodied carbon solutions

Innovations such as SENSE 600® help customers reduce material use while maintaining structural performance. Less steel can mean lower embodied carbon outcomes.

Local manufacturing

Manufacturing steel in Australia strengthens sovereign capability, reduces supply chain complexity and supports local jobs and communities.

1.4M tonnes

of scrap steel recycled annually

77%

fewer greenhouse gas emissions from electric arc furnace steelmaking compared with traditional blast furnace steelmaking*

Helping customers build smarter

Sustainability and productivity don't need to compete. Through higher-strength steel, engineering expertise and advanced manufacturing, we're helping customers reduce material use, improve construction efficiency and lower embodied carbon. It's a practical approach that delivers better outcomes for projects, communities and the built environment.
