It is a general term used to describe structural steel beams — technically Universal Beams (UBs) — that are hot-rolled into an I-shaped cross section. RSJ, steel beam, I-beam, steel joist and universal beam all refer to the same type of section. The correct modern designation is Universal Beam (UB) with properties defined under BS EN 10365.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat sizes do RSJ steel beams come in?\u003c\/strong\u003e\u003cbr\u003eOur RSJ beams range from 127 x 76 UB13 up to 254 x 146 UB37, covering the most commonly specified structural steel beam sizes for domestic and light commercial work.

A Universal Column (UC) has a squarer, wider profile where the flange width is roughly equal to the depth, optimised for carrying vertical compression loads — posts, columns, vertical supports.

It is a general term used to describe structural steel beams — technically Universal Beams (UBs) — that are hot-rolled into an I-shaped cross section. RSJ, steel beam, I-beam, steel joist and universal beam all refer to the same type of section.

Heavier and stiffer than the UC23, it is typically specified where greater axial load capacity is required within the same 152mm column family.

The thicker flanges (11.5mm) and web (8.1mm) give it substantially more stiffness than the UC23 or UC30.

It is commonly specified for steel-framed buildings, mezzanine floor columns, commercial and light industrial structures and fabricated steel frames where this section has been confirmed by a structural engineer.
