The lightest beam in the standard universal beam range, and the one most often specified where the opening is modest and the load above it is light.

127 x 76 x 13 dimensions and weight

Approximate total weight by length — this is what determines how the beam is offloaded on site.

What is a 127 x 76 x 13 used for?

The 127 x 76 x 13 is the smallest section in the UB range and sits at the point where a steel beam starts to make more sense than a timber or concrete lintel. It turns up most often in small internal openings, short trimmer beams around stairwells and loft hatches, and light non-structural or lightly loaded partitions. At 13 kg per metre it is also the only UB in common use that two people can reasonably lift and position by hand over a short length, which is why builders reach for it on jobs with no crane access and tight interior stairs. It is not a beam for spanning open-plan rooms or carrying floor loads over any distance. If your engineer’s calculations are pushing toward 3 metres or the beam is picking up a floor as well as a wall, expect to move up to the 152 x 89 x 16.

Indicative span

Under typical UK domestic loading, published load tables place the 127 x 76 x 13 in the region of 2m to 2.5m. That assumes a simply supported beam with an evenly distributed load, an imposed load of around 1.5 kN/m² and a dead load of 0.5–0.8 kN/m².

Grades, lengths and finishes

The 127 x 76 x 13 is normally supplied to BS EN 10025-2 in S275JR or S355JR. S355 is the higher strength grade and is increasingly the default across the supply network; if your calculations specify one grade, tell us, because the two are not interchangeable. Mill certificates can be supplied with the order on request.

Beams are supplied cut to your lengths rather than as standard mill lengths, and we can arrange:

• Cutting to size — supplied ready to install, no cutting on site
• Drilling, notching and holes to your engineer’s details
• Welded cleats, end plates and connections
• Painting and priming, including intumescent coatings
• Galvanising for external or exposed applications

Delivery

A 6m length of 127 x 76 x 13 weighs approximately 80kg. That is within reach of manual handling over a short distance with enough people, though it is rarely pleasant. We deliver direct to site across London, the South and the Midlands, with HIAB lorry crane offload available on request. If access is restricted — a terraced street, a rear garden, limited headroom — tell us at quote stage rather than on the day, and we’ll plan the delivery around it.

Other sizes in the range

Also searched as: 127x76x13, 127 x 76 x 13 UB, UB 127x76x13, 127×76 RSJ. The term “RSJ” is still widely used for universal beams, though strictly it refers to the older rolled steel joist section with tapered flanges.

• All universal beam sizes
• Universal columns (UC) — where the load is vertical rather than spanning
• RSJ beams
• PFC parallel flange channels
