The beams are continuously formed, so the length of the beam is limited only to the maximum length that can be handled and transported. Typical widths are 3 + 1 ⁄ 2, 5 + 1 ⁄ 4 or 7 inches (89, 133 or 178 mm); typical depths are 9 + 1 ⁄ 2, 11 + 7 ⁄ 8, 14, 16 and 18 inches (240, 300, 360, 410 and 460 mm).

An axlebox, also known as a journal box in North America, is the mechanical subassembly on each end of the axles under a railway wagon, coach or locomotive; it contains bearings and thus transfers the wagon, coach or locomotive weight to the wheels and rails; the bearing design is typically oil-bathed plain bearings on older rolling stock, or roller bearings on newer rolling stock.
The bottom of the beam has multiple connection points for hanging the load. [1] H-shaped traverse. The lifting beams are used in multiple cases: [2] lifting an asymmetrical load. Without a beam, it might be hard to strap the load so that its center of gravity is exactly below the hook; handling a long load with a single-hook crane.

Tables are available to allow easy selection of a suitable steel I-beam size for a given applied load. I-beams may be used both as beams and as columns. I-beams may be used both on their own, or acting compositely with another material, typically concrete. Design may be governed by any of the following criteria:
