Angle bars are used to offer a strengthened support to structures that otherwise would not be able to endure the pressure placed on them. They are also used to reinforce edges on surfaces to prevent damage or erosion due to weathering. In the simplest sense, angle bars are used to protect any edges and corners that are required to hold their shape.
Angle bars can also be used as a means of providing vertical as well as horizontal support for a steel tube structure. They are most commonly used in structures such as radio towers and broadcasting equipment. This is because of the material’s natural ability to resist weathering and oxidization, while also providing a great amount of tensile and resistance strength to the structure they are incorporated into.
