Structural Tees Cut From UBs - 127x152x21

Structural Tees cut from Universal Beams (UB) are T-shaped steel profiles created by splitting a standard "I"-shaped Universal Beam lengthwise down its center vertical web. This process splits one beam into two identical "T" sections, each consisting of a single horizontal flange and a vertical stem. Engineers use these sections when a standard structural shape is too deep or heavy, as they offer excellent tension and bending strength along the vertical stem. They are highly popular choices for the bottom chords of roof trusses, bracing elements, or as clean, neat architectural connections where an "I" beam would look too bulky.
