Angles provide two directional support, in hidden or exposed applications. Slots, notches and other holes are often included. Cold roll formed angles have many advantages over hot mill formed angle iron. Lower quantities can be cost effective and pre- and post-fabrications are cheaply done and with better results. Overall, tolerances are closer to true with less deformity in gage. Angles are ubiquitous in hundreds of industries, anywhere cheap but effective support, strengthening, stiffening, edging, bracing and framing is required, especially in construction.
