FRAMING SYSTEM
The internal framing system is a portal frame, however instead of a hot rolled section the frame uses a cold formed UB section strengthened with hot dipped galvanised gusset plates bolted to each face of the cold formed UB's web section at each the main bending moment junctions. The system has been produced by local company GALFRAME .
Introduction
I passed this site just after Christmas on my push bike. At first glance it appeared to be an ubiquitous portal frame. However the shining relfections from the frame signalled that it was different.
The portal frame was not your normal hot rolled steel UB section but cold rolled. The type you usually see in those kit garages and barns, but this spans 20m!

This is an interesting variation to typical portal frame construction.
Your photos & comments are good, & your analysis indicates that you have grasped the concept & details of portal frame construction.R.K.
