Steel Angles are the most basic type of roll-formed steel. They are formed by bending a single angle in a piece of steel. Angle Steel is ‘L’ shaped; the most common type of Steel Angles are at a 90 degree angle. The legs of the “L” can be equal or unequal in length.
Steel angle is measured on the outside of the leg with the thickness measured in the middle of the leg. Structural angles are those whose greatest dimension (not including length) is three inches or greater.
