How to tell the difference between universal beams and universal columns, which are both referred to as ‘I-section’ and ‘H-section’ is the UB depth being much greater than its own width so it’s very easy to see.

​

 

Just like the UC it is easy to work out what the total weight of a UC is by multiplying its total length in metres by its weight per metre.

​

Using the first measurement on the chart as an example; 

• 127 x 76 UB 13

• 127 mm = depth (height)

• 76 mm = width

• 13 = weight per metre in kilograms.

 

These are most often used on;

The increased depth results in higher loading capabilities than UCs, however there is not always enough space to use a UB.
