Rolled Steel Angle (RSA-U)

Hot Rolled Steel Angle (RSA-U)

They are described by giving both leg lengths (longer first) and the wall thickness (all in mm), eg. 150 x 100 x 8 RSA. With the longer leg being in a vertical position, its loading capabilities are greater than equal angles, therefore they are often used as lintels.

Unequal angles are also used as brackets for cleat connections. Similar to equal angles, they are often used for balconies, platforms, stairs, concrete supports, etc.
