Angle Bars is a steel bar shaped like an L. One angle is perpendicular to the other. This forms an inside angle as well as an outside angle. it is used to create supported corners and outside rims. These corners and rims are used for various walls and surfaces. Such bars are easily applied to virtually any type of surface through welding or by using drilled fastening methods. 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.
