UniversalBeams
Hot-rolled universal beams (UB) — structural steel I-beams for floors, roofs and primary building frames.


Universal beams (UB) — also called steel I-beams — are hot-rolled structural sections with wide flanges, used as the primary load-bearing members in floors, roofs and building frames. We supply the full range of universal beams from 150 UB to 610 UB in Grade 300 to AS/NZS 3679.1, with mill test certificates and full traceability. Cutting, drilling and surface treatment are available to suit your fabrication programme.
