RSJ Steel Australia

Searching for RSJ steel in Australia usually means one of two things: you’ve got a wall coming out and an engineer’s spec in hand, or you’re speccing a full steel package for a new build and need a supplier who won’t make you chase five separate quotes. Either way, AST supplies rolled steel joists, also called universal beams or I-beams, to builders, renovators and trades across the country.

Built For Load-Bearing Work

AST’s RSJ steel is supplied to Australian structural grade, sized to your engineer’s specification for floors, ceilings and load-bearing walls. We hold standard lengths in stock and cut to custom sizes through our fabrication partners, with delivery arranged direct to site across Sydney, Brisbane, Melbourne and beyond. (47 words)

Where RSJ Steel Gets Used

Home extensions and knock-through renovations removing a load-bearing wall
New builds, where the beam forms part of the structural skeleton
Warehouses and commercial fit-outs needing wide-span support
Landscaping and outbuilding projects needing a structural support beam

Standard Or Cut-To-Size

If your spec matches a standard length and profile, we can usually supply it straight off the shelf. Non-standard sizes go through our fabrication partners, factor in extra lead time for that and get your measurements confirmed early, changing a spec after fabrication starts is the kind of delay nobody wants on a live job.

Where Our Steel Comes From

We source through local mills and overseas partners we’ve worked with for years, which means we’re not stuck if one supplier is out of stock on your exact size. That’s the advantage of a sourcing network over a single-mill supplier: more paths to the same product, so your delivery date doesn’t depend on one warehouse’s inventory.
