Similar to universal columns, Universal Beams (UB) are referred to as “I-sections” or “H-sections”. The depth of a UB is greater than its width and the difference is quite big, making it easy to spot. The increased depth results in higher loading capabilities than UCs, however, there is not always enough space to use a UB. An example is a 203 x 133 UB 30. The first number is the depth of the beam, the second is the width and the last number is the weight (in this case 30) per metre in kilograms. Again, by multiplying the total beam length in metres by the weight per metre we can quickly work out what is the total weight of the beam.
