Our Steel Portal Frames
Steel portal frames have a range of uses from light duty walkway portals, residential housing wind bracing portals, through to commercial portal frames used to create large unsupported spans. Smaller portals can be fully shop welded assemblies but larger portals are typically bolted connections for transport purposes with optional shop welded haunches. Portal frames are generally manufactured from RHS, SHS, U-Beam or PFC sections. On larger commercial/industrial projects in Brisbane, structural steel portal frames being used in conjunction with steel roof bracing, purlins & girts are fully workshop drawn by a steel detail draftsman to produce cad details for engineers approval prior to manufacture.
