universal beam (UB)
Universal Beam

The Universal Beam (UB) replaced the old "Rolled Steel Joist" (RSJ). It is probably the most widely used structural member. Each size comes in a range of thicknesses, designated by weight.

We can supply UB's in a plain mill finish, or Primed or Hot-Dip Galvanized if required. Contact us for a quote.

The list below shows each size together with its dimensions.
