Equal and unequal are the two major types of steel angle:Steel angles are fashioned using a single flat steel section and bending it, generally at a 90-degree angle with both legs the same size. See below for a rundown of the different steel angle types:
Equal angle
Equal steel angles have 2 axes' that are the same length, hence their name. They are the most common types of steel section and can be made to various specs and cut to any size, making them extremely versatile. Their sizing is represented by side A x side B x thickness.
Unequal angle
Unequal steel angles are also right-angled; however, they have different sized axis' making them L-shaped. This section is much stronger (up to 20%) with a much higher strength to weight ratios. Their sizing is represented by side A x side B x thickness.
