406 x 178 x 74 kg Universal Beam S355
Rolled as a universal beam measuring 412.8 × 179.7 mm, the 406 x 178 x 74 kg Universal Beam S355 carries load in bending across a span rather than in axial compression. Because most of the steel sits in the flanges, this profile is efficient in major-axis bending but comparatively weak about the minor axis — lateral-torsional restraint at the compression flange is usually what governs the design.

At 74 kg per metre, one tonne buys roughly 13.5 linear metres. This is a substantial member. Connection design, bearing detail and temporary stability all deserve attention at the drawing stage. Held in S355 to BS EN 10025-2 and cut to length before it leaves the yard. Mill certificates accompany every load, and any fabrication is executed under our BS EN 1090 EXC 3 factory production control.
Typically specified for crane gantry runway support, floor and roof beams, portal-frame rafters, opening lintels in load-bearing walls and transfer beams over removed walls.
Where a beam bears on masonry, remember to specify padstones separately — they are a design item, not part of the steel supply.

FAQs
406 x 178 x 74 kg Universal Beam S355,
answered.
Common questions about the 406 x 178 x 74 kg Universal Beam S355 — weight, grade, cut-to-length and worldwide delivery.
- It weighs 74 kg per linear metre, so a tonne is approximately 13.5 metres. A 6 m length comes to about 444 kg. Use the figure for lifting plant selection and for pricing, since structural steel is sold by weight.
