UB – universal beam
So also to all inclusive segments, widespread shaft are alluded to as “I-segments” or “H-areas”. The profundity of a UB is more noteworthy than its width and contrast is entirely huge, making it simple to spot. The expanded profundity results in higher stacking abilities than UCs, however there is not generally enough space to utilize a UB. An illustration is a 203 x 133 UB 30. The primary number is the profundity of the pillar, the second is the width and the last number is the weight (for this situation 30) per meter in kilograms. Once more, by duplicating the aggregate bar length in meters by the weight per meter we can rapidly work out what is the aggregate weight of the bar.
