Angle bars are often referred to as L bars, L-shaped bars, or simply angles. These are metal bars with two sides that form a right angle. They are commonly used in construction and are available in various sizes and thicknesses to suit different applications. Other synonyms for angle bars include corner guards, corner protectors, and steel angles. Some other similar shapes in construction are U-bars and T-bars. The former is also known as channel bars and the latter as beam bars or flanged bars. These shapes are often used as support structures for building frames, roof trusses, and other infrastructure components.
