The Stainless Steel Unequal Angle is used in more corrosive applications than the 304 angles could be used. The Stainless Steel Unequal Angle is as common as the equal angle. They are used in brackets, trim, reinforcements and in other applications as well. The angles are used to connect components together with a grip. There are angles with bolt holes for bolts or screws as well.
