The process starts at major steel mills – BlueScope is the biggest manufacturer in the country with over 100 sites, and between it and InfraBuild (formerly Liberty OneSteel), they handle most domestic production. BlueScope’s Port Kembla facility in NSW produces about 3 million tonnes annually, whilst InfraBuild runs electric arc furnaces in Sydney, Melbourne, and Newcastle.
Raw material logistics involve moving iron ore primarily from WA’s Pilbara region and coal from NSW and Queensland to these mills. Most transport happens via rail to port, then coastal shipping to the mills.
The Distribution Network
The distribution network works on multiple tiers: primary distributors maintain large service centres near major ports and industrial hubs. They handle heavy plate, structural steel, and bulk orders. Companies like Southern Steel, Steel Suppliers, and OneSteel Metalcentre operate these facilities with overhead cranes and heavy transport capability.
Secondary distributors work regionally, running smaller warehouses that stock common sizes and grades. They typically maintain 2–4 weeks of inventory and service local fabricators and manufacturers.
Processing Centres
Processing centres play a crucial role. They handle:
- Plate cutting and profiling
- Beam line processing
- Surface treatment and coating
- Custom fabrication
The construction sector takes about 60% of steel supply, whilst manufacturing uses roughly 30%. Most deliveries to construction sites require specialised transport – you’ll see lots of extendable trailers handling long sections and specialised rigids for plate delivery.
Main Headaches in the Steel Supply Chain
There are various challenges that affect how efficiently the steel supply chain runs. Some examples include:
- Port congestion affecting import timing
- Rising transport costs, especially for regional delivery
- Inventory management during demand spikes
- Meeting sustainability requirements from major projects
Sustainability is a big one, with many companies increasing their focus on this over the past decade, mainly due to issues like transport emissions reporting becoming mandatory and local councils pushing for increased recycled content.
The steel industry is split between producing for the construction and manufacturing industries, with both generally requiring specialised transport to be in place (for obvious reasons, due to steel’s high density). Though it isn’t without its challenges, the industry has steadily grown each decade since the 1950s, so it doesn’t look like it’s going anywhere anytime soon.
