700WB173
Welded Beam · AS/NZS 3679.2 · Australia / New Zealand
700WB173 is a welded beam 716.0 mm deep with a 275.0 mm wide flange, weighing 172.7 kg/m. The dimensions below are the published AS/NZS 3679.2 values; the drawing is generated from them.
Welded Beams are fabricated from three plates to AS/NZS 3679.2, extending the rolled UB range to depths and capacities rolling cannot reach. A welded section has square corners by construction.

Derived section properties
Integrated from the section's exact plate outline — a welded section has square corners by construction, so nothing is approximated. For 700WB173 the computed area agrees to better than 0.01% and Ix to better than 0.01%. Where a value is also published, the published one above is the one to quote.
| Property | Value |
|---|---|
| Elastic modulus, Zx | 5,762,460 mm³ |
| Elastic modulus, Zy | 706,233 mm³ |
| Plastic modulus, Sx | 6,386,600 mm³ |
| Plastic modulus, Sy | 1,075,250 mm³ |
| Radius of gyration, rx | 306.2 mm |
| Radius of gyration, ry | 66.4 mm |
Z is the elastic modulus and S the plastic modulus, following AS 4100. Under AISC 360 the letters are reversed.
