An angle bar also referred to as an angle iron or L-bracket, is a finished metal part in a right angle shape, with perpendicular legs that may be equal or unequal in length. It is typically manufactured through hot rolling carbon steel or a high-strength, low alloy steel that is highly ductile and machinable. Due to the versatility of this product, angle bar uses can be found in many situations. Some of these include bridges, building construction, shelving units, warehousing, or even equipment manufacturing.

Once assembled with other structural components, angle bars offer optimal stability and durability. The hot rolling production process allows these materials to exhibit low deformation resistance as well as relieve internal stresses in their metallurgical structuring, making them effective for many purposes.
