Purlin/Girt Identification

[handex]

Hi all. We have been given the job of checking an existing steel portal frame factory that was never certified. It has quite an odd layout of lateral bracing, and the portals consist of square hollow section flanges with corrugated plate webs, 1500mm deep overall. Anyway the last thing to verify is the existing purlins and girts, and I was hoping somebody here could help identify the manufacturer or some design tables, purely to avoid going through all the calcs in the cold form steel code. The project is in Queensland, Australia, if that makes any difference. The measurements in the sketch are only approximate (provided by the architect who is redrawing the factory). Will be heading out sometime next week to properly measure up the job and determine thicknesses etc.

Any guidance would be much appreciated.

Cheers

I think those are purlins for what used to be called Stramit board ceiling panels, but is now apparently called Durra board by Ortceh Systems.
