The maximum slope for a steel angle depends on various factors such as the size, shape, and thickness of the angle. However, in general, steel angles are designed to withstand vertical loads and provide stability in structural applications. Therefore, the maximum slope for a steel angle is typically limited to angles less than 45 degrees. Going beyond this angle may compromise the structural integrity of the angle and increase the risk of failure. It is important to consult engineering codes, standards, and specifications to determine the specific maximum slope for a particular steel angle in a given application.
