Truss & Joist Beams for Spans Solid Beams Can't Reach — Fabricated to the Code Your Authority Speaks
A truss puts every member into pure axial work, so 40 m column-free comes at a fraction of a solid beam's steel. The hard part was never the geometry — it's the paperwork your local authority accepts. We hold to AISC, Eurocode, AS/NZS and more, and ship the certificate trail to match.
Spans 18–60 m column-free halls, logistics, sports | Up to 40% Less Steel vs solid members, same coverage | Multi-Code Certified AISC · EN 1090 · AS 5131 · ISO 3834 | Full Paper Trail mill certs, NDT & weld logs shipped |

Which Code Does Your Building Speak? — Multi-Country Certification Matrix
Trusses fail approval not in the air, but at the permit desk: wrong bolt standard, undocumented welder, missing CE or AS certificate. Tell us your market — we deliver on its home code:
| Your market | We design & detail to… | Fabrication backing you receive |
|---|
| USA, Caribbean, Panama | AISC 360-22 · AWS D1.1 structural welding · ASTM A36/A572 · A325/A490 high-strength bolts | AISC member shop practice; welder qualifications & NDT reports in your drawing set |
| EU, UK, Middle East (EN route) | EN 1993 Eurocode 3 · EN 14399 HR bolts · EN 10025 steels | CE execution to EN 1090 · ISO 3834 welding quality · UKAS-certified processes · EN 10204 3.1 mill certs |
| Australia / New Zealand | AS 4100 design · AS/NZS 1170 loads · AS/NZS 3679 steels | Fabrication to AS 5131, welding to AS 1554 — certificates citing the AS grades your certifier asks for |
| Africa, SE Asia, LatAm (mixed) | British-code legacy, AISC practice, or your engineer's spec — we match whatever your stamp requires | Send the permitting authority's name with your inquiry; the code question gets answered in quote #1, not after shipping |
Rule of the house: one project never gets "GB drawings with an English translation." The design standard, the bolt standard and the certificates leave our gate speaking the same language as your authority.
The Truss Saves You Money Three Separate Times
① At the steel a solid beam wastes its middle fighting bending; truss chords + web members carry pure axial load — up to 40% less steel for the same roof | ② At the ground a lighter roof line means smaller columns, lighter bases and shallower foundations — the cheapest concrete is the concrete you never pour | ③ At the freight trusses ship as compact bolted bundles — fewer tons, fewer containers, more span per dollar of sea freight |
And one saving that never shows on the invoice: triangulated frames reach 18–60 m without a column in your floor plan — your layout stops negotiating with structure.
