Our Cut To Size Universal Beam, UBs or I-Beams, are steel sections available in a range of sizes, weights and finishes to suit your next structural steel support and building construction projects. They can bear incredibly high loads and also reduce the requirement for multiple support elements in construction.

The Universal Beam’s vertical side resists the sheer force exerted upon it, while the flanges help the beam resist the load’s pressure, which would otherwise cause it to bend. Providing long-lasting and reliable stability and support, they provide an even weight distribution of consistently weighted heavy loads across the length of the beam support. 

The parallel flange of the Universal Beam does away with the need for tapered washers and makes it easier to connect than the flanges of Rolled Steel Joists (RSJ), which vary in thickness. The depth of a UB is always greater than its width, making it more suited to carrying bending loads (forces applied to it in the middle or on the end) such as the beam elements in floors.

Our Universal Steel Beams can be used in a wide variety of structural steel applications. They can be cut and welded and are available in either self colour or a red primer. These steel beams can also be easily recycled, repurposed and reused to help you manage and reduce costs. 

Key features:

  • Available in self colour or red primer
  • Enter your size requirements to get an instant price
  • Universal beams are available for local delivery only

The cross-sections are commonly specified with a code consisting of the dimension. The first dimension is always the depth, followed by the width and finally weight, in kilograms per meter. For example, 152x89x16, would be 152mm in height, 89mm in width and 16KG per meter of length.

Great serviceReviewed by Neil.forbes63 on 13 Oct 2023

Excellent communication, quick efficient service and competitive pricing, thank you


BRILLIANTReviewed by Roger.backaller on 26 Oct 2022

Thanks Austen Knapman. I ordered what I required online and found the website easy to use bearing in mind my limited computer skills!! The beams arrived within days and were dropped just where they were required. They fitted perfectly and are all now 'built in'. I would have no hesitation in recommending Austen Knapman.
