The I beam, also referred to as H beam or universal beam (UB), is the structural steel of choice for most construction applications. The unique structural build and design of the I beam makes it capable of handling a variety of loads. The I beam consists of two horizontal planes, known as flanges, connected by one vertical section, or the web. The shape of the flanges and the web create an “I” or “H” cross-section. I beams are usually made from structural steel, but some are made from aluminium. The I beam size, weight, section depth, flange width, web thickness and other specifications differ depending on different purposes.
Uses of I beam include construction, engineering, support frames and columns for trolley ways, lifts and hoists, trailer and truck bed framing, bridges, factory shops, warehouses, workplace platforms, heavy machinery and structural support applications.
Two of the most utilized grades of I beams are EN 10025 S275 and BS4360 Grade 43A. EN 10025 S275 is a popular mild steel grade suitable for various use in construction and structural applications. Having low carbon steel specifications, EN 10025 S275 provides great machinability and high weldability with moderate strength. Structural steel grade S275 is widely used in the construction, maintenance and industrial industries.
Mild steel grade BS4360 Grade 43A is another widely used carbon structural steels, which is suitable for a large number of construction projects. It is cheaper than most other structural steel grades, which makes it suitable for different applications such as building and machinery constructions that do not require wear-resistance and high strength.
