Unequal Angle

Unequal Leg Angle (UA) having one longer leg can provide additional strength in a continuously restrained arrangement when compared to Equal Leg Angle of a similar size. Steel angles are typically used for frames, sub-frames, composite and truss structures as well as brackets. Steel angles are ideal for structures that are both light weight and long lasting and can provide reinforcing at edges of a surface to prevent buckling and thus allowing structures to support greater loads. Steel angles are also ideal for corner pieces where the flat legs make ideal connection points.
