High Strength Bolts (HSB) For Steel Structure-HEAVY HEX STRUCTURAL BOLTS
Share to:

Overview

An H beam and I beam, when looked at in cross section, has the shape of the capital letter H or I. It's formed with a tall vertical plate and shorter horizontal plates on top and bottom. The vertical plane is called the web, while the horizontal planes are called the flanges. Usually, steel makers produce I beams using the hot rolled method for maximum strength. However, the "I" configuration can also be achieved through the welding together of other steel shapes by a fabricator if needed.

Most commonly, builders use I beams for the floor joists and truss systems in steel-framed projects. While they can also serve as columns, other beams with thicker, longer flanges and thicker webs — H beams — often work better for the vertical loads. The I beam configuration offers so much strength, they function best for long, unsupported horizontal spans and cantilevered architectural elements.
