Rolled Steel Angle (RSA) - e
Even though both legs are the same length, they are described by giving both leg lengths and the wall thickness (all in mm), eg. 100 x 100 x 12 RSA. For structural steel purposes, equal angles are most often used for brackets for cleat connections. Sometimes they are also used as lintels (2 angles bolted back to back). They are often used for balconies, platforms, stairs, concrete supports, etc.
