Roll Formed Metal Angles are the most basic of all Roll Formed Profiles. Tooling required is simple, and inexpensive to setup. For 90 degree leg angles, tooling is always existing, up to 4" O.D. leg height using up to a 3/16" maximum thickness, and up to a 9" O.D. leg height using a .075" maximum thickness. Aluminum maximum thicknesses can be thicker than 3/16" and .075". Legs can be as short as .090" tall, though, very short legs can involve die modifications for trapping the legs in place. On thinner materials, hemmed legs can also be added with existing tooling. Most Angles have equal legs but we get requests from many customers for unequal leg angles also called L\u0027s. We specialize at producing Angles that are thinner or the same thicknesses but have unequal legs that are not available as a Hot Rolled Mill Angle, Extrusions or as Angle Irons. On thicker materials it is always good to remember that unlike hot rolled mill angles which have a sharper outside corner and a large inside corner, Roll Formed Angles have a larger outside corner radius and a sharper inside corner radius. As with all roll forming, the outside radius is the total of the inside corner plus the metal thickness. Material thicknesses can be from .005" through .188" thick. Angles we can supply come in many types of metal including steel, aluminum, brass, and stainless steel.
