Welded Beam · AS/NZS 3679.2 · Australia / New Zealand
700WB130 is a welded beam 700.0 mm deep with a 250.0 mm wide flange, weighing 130.3 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 700WB130 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 | 3,988,324 mm³ |
| Elastic modulus, Zy | 417,107 mm³ |
| Plastic modulus, Sx | 4,489,000 mm³ |
| Plastic modulus, Sy | 641,500 mm³ |
| Radius of gyration, rx | 290.0 mm |
| Radius of gyration, ry | 56.0 mm |
Z is the elastic modulus and S the plastic modulus, following AS 4100. Under AISC 360 the letters are reversed.
