Introduction to I Beam
An I – beam, also known as H – beam, W – beam (for “wide flange”), universal beam (UB), or rolled steel joist (RSJ), is a beam with an I or H – shaped cross – section. The horizontal elements of the I are flanges, while the vertical element is the web. The shape of the I beam provides excellent structural strength and stiffness with relatively less material compared to solid beams of the same depth. This makes it an ideal choice for a wide range of construction and engineering applications, such as building frames, bridges, industrial structures, and machinery supports. I Beam
