RESOURCES / Steel Size Reference
Steel Size Reference — Gold Coast
Every standard steel size we stock at the Burleigh Heads yard, in one place. Sourced from public Australian Standards.
This is the master reference page for steel sizes stocked at Marshall Steel. If you need quick numbers — wall thickness on a 100×100 SHS, mass per metre on a 250UB, mesh aperture on an SL82 sheet — it's all here. Each family also has its own dedicated page with finish options, applications and quotes. Tables are drawn from the public Australian Standards: AS/NZS 1163, AS 1074, AS/NZS 3679.1, AS/NZS 4671 and AS 1397.

FAQ
Common questions on steel sizes.
- What standard sizes of steel does Marshall Steel stock?
- We stock the full range of Australian standard sections: SHS 20×20 up to 250×250, RHS 50×20 up to 250×150, pipe 15NB through 150NB, equal and unequal angle, flat bar, round bar, square bar, PFC channel 75 to 380, universal beams 150UB to 610UB, universal columns 100UC to 310UC, plus SL reinforcing mesh and N-grade reo bar. Full size tables on this page.
- What's the heaviest universal beam (UB) you stock?
- 610UB125 — 612mm deep at 125 kg/m — is the heaviest UB off the rack at the Burleigh Heads yard. Heavier mill lengths are available on order.
- Do you cut every standard size to length?
- Yes. Bandsaw cut-to-length is standard service across every section we stock — SHS, RHS, pipe, angle, flat, round, square, PFC, UB and UC. Send a cut list and we'll have it ready for pickup or delivery.
- What grade is your structural steel?
- Hollow sections (SHS, RHS, CHS) are Grade C350L0 to AS/NZS 1163. Hot-rolled sections (angle, flat, round, square, PFC, UB, UC) are Grade 300 to AS/NZS 3679.1. Reinforcing is N-grade (500 MPa) to AS/NZS 4671. Pipe is medium-grade to AS 1074.
- What standard lengths does steel come in?
- Hollow sections (SHS, RHS) are stocked in 6.0m and 7.5m. Hot-rolled bar (flat, round, square, angle) is 6.0m standard, with angle also in 9.0m. PFC and UB/UC are 9.0m and 12.0m mill lengths. We cut all of them to size on request.
- What sizes of galvanised steel do you stock?
- DuraGal (in-line galvanised) is stocked in the common SHS and RHS sizes through to 100×100 and 150×100. Hot-dip galvanised supply is available across every section — sent out for galvanising to AS/NZS 4680 after fabrication.
- Do you stock reinforcing mesh and reo bar to AS/NZS 4671?
- Yes — SL square mesh from SL62 through SL102 in 6.0m × 2.4m sheets, F-series trench mesh, and N-grade deformed reo bar from N12 to N40 in 6.0m, 9.0m and 12.0m lengths.
- Can I get a printed copy of these size tables?
- Yes — use your browser's print function to save this page as a PDF, or pop into the Burleigh Heads yard for a printed copy. The mm-to-inches conversion chart and the section quick-reference are also available as separate printable resources.
- Do you stock non-standard sizes on request?
- Yes. Anything inside the Australian Standards range we can source — call 07 5576 6037 or send the spec through and we'll get back with availability and lead time, usually same day.
- Where do these size tables come from?
- The size, thickness and mass data on this page is sourced from the public Australian Standards: AS/NZS 1163 (hollow sections), AS 1074 (pipe), AS/NZS 3679.1 (hot-rolled bars and sections), AS/NZS 4671 (reinforcing steel) and AS 1397 (galvanised products).
