Steel design tools
Free tools for working with Australian steel sections. More tools are planned. Tell us what you'd like next.
Beam calculatorSimply supported or cantilever beam: M*, V*, deflection, φMb with lateral-torsional buckling, and the lightest sections that pass.
Section finderLightest section that meets your φMb, φNc, φVv, Ix, depth and mass limits.
Compare sectionsUp to four sections side by side with overlaid outlines.
Lateral restraint calculatorRestraint types, ktklkr, αm, φMb, full-lateral-restraint spacing and restraint forces to AS 4100.
Steel weight calculatorMass, cost estimate and coating area for a cutting list of sections and plate.
Member capacity calculatorφMb and φNc for any length. Available on every section page.
Bolt capacitiesAS 4100 design capacities of M12–M36 4.6 and 8.8 bolts in shear, tension and friction, ply bearing, holes and edge distances.Weld capacitiesFillet weld design capacity per millimetre for SP and GP welds, with long-weld reduction and butt weld notes.
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)
