As the name suggests, the I-beam is an “I”-shaped cross-section steel. The inner surface of the upper and lower flanges has a slope, so the cross-sectional properties of the I-beam on the two main planes are very different, and it is difficult to use the steel in the application. strength properties. Although thickened I-beams have also appeared on the I-beam market, the structure of I-beams has determined its shortcomings in torsional performance.
Widely used in various building structures and engineering structures, such as beams, bridges, transmission towers, lifting and transportation machinery, ships, industrial furnaces, reaction towers, container racks and warehouse shelves, etc.
The selection of I-beams in structural design should be based on its mechanical properties, chemical properties, weldability, structural dimensions, etc. to select reasonable I-beams for use.
