Steel angle iron is a length of steel or iron bent at a right angle along its longest dimension (length). It is most commonly used as a support or structural framework in buildings of all types. Angle iron is typically sold in 20 foot lengths and is 2.5 inches wide, although it is available in other widths, depending on need. Using modern tools and technology, along with the addition of
. computer-aided machinery, it is possible to create angled iron in literally any length, angle and width. Regardless of thickness, with proper working and the proper tools, it is easy to bend any size steel into the required angle iron.Angle iron, similar to other steel products, is produced using one of two methods. These are cold rolling and hot rolling. Cold rolling is a metalworking process in which metal is manipulated by passing it through rollers at a temperature below that required for re-crystallization, which results in metal that is flexible and able to retain most of its original strength. Structures that are made with cold-rolled iron products are most often residential or office buildings, though in some climates many workshops and barns also use cold-rolled iron.Hot-rolled iron, as the name implies, is created using heat and presses to form the desired angle. Hot-rolled products are rougher in appearance and more difficult to work than ones that are cold-rolled, but the added inflexibility is countered by the benefit of extra strength. Hot-rolled iron products are perfect for industrial settings, where strength is often more important than the aesthetic appeal of angle iron.Depending on the reason a person needs angle iron, it is easy to get it in any size; if custom angles or lengths are needed, the cost is going to raise in relation to the amount of work required to reach specifications.
