Universal beams (UB), and commonly referred to as “I” beams, are named after the ‘I’ shaped appearance of their cross section. The vertical “web” of a Universal Beam is significantly longer than the horizontal “flange”. Commonly used on the horizontal in building structures to support floors or roofs. universal beams are structured to hold loads along the length of the beam and are structured to resist bending from the weight of the load.
