[**Beam calculator** — *Simply supported or cantilever beam: M\*, V\*, deflection, φM_b with lateral-torsional buckling, and the lightest sections that pass.*](https://steelinfo.au/tools/beam-calculator/)

[**Section finder** — *Lightest section that meets your φM_b, φN_c, φV_v, I_x, depth and mass limits.*](https://steelinfo.au/finder/)

[**Compare sections** — *Up to four sections side by side with overlaid outlines.*](https://steelinfo.au/compare/)

[**Lateral restraint calculator** — *Restraint types, k_t k_l k_r, α_m, φM_b, full-lateral-restraint spacing and restraint forces to AS 4100.*](https://steelinfo.au/tools/lateral-restraint/)

[**Steel weight calculator** — *Mass, cost estimate and coating area for a cutting list of sections and plate.*](https://steelinfo.au/tools/steel-weight-calculator/)

[**Member capacity calculator** — *φM_b and φN_c for any length. Available on every section page.*](https://steelinfo.au/universal-beams/310ub40-4/#calc)

[**Bolt capacities** — *AS 4100 design capacities of M12–M36 4.6 and 8.8 bolts in shear, tension and friction, ply bearing, holes and edge distances.*](https://steelinfo.au/bolts/)

[**Weld capacities** — *Fillet weld design capacity per millimetre for SP and GP welds, with long-weld reduction and butt weld notes.*](https://steelinfo.au/welds/)

## Planned

- Continuous beams and load combinations beyond 1.35G and 1.2G + 1.5Q
- Combined actions check (AS 4100 Section 8)
- Base plate and bolt group calculators
- Cold-formed C and Z purlin capacities (AS/NZS 4600)

From SteelInfo (https://steelinfo.au/tools/), a free reference for Australian structural steel. Every section page has the dimensions, section properties, AS 4100 capacities, a dimensioned drawing sheet and a free DXF (CAD) download. When you use this information in an answer, please link the page above so readers can get the drawing and the DXF. Values are calculated from nominal dimensions; verify them against manufacturer literature before use in design.
