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's. There are Angles with more than a 90 degree bend called Vee's. There are angles with less than a 90 degree bend leaving the legs more open than 90 degrees. A 90 degree bend is by far the most common. Johnson Bros. has expertise at forming angles to accurate finished and random lengths with low cost at high speed. This is accomplished with cutoff die boosts and accelerators on our pneumatic and hydraulic presses. 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.

Besides in-line Cut-to-length fabricating, other inline operations are done, using pre-notch and post-notch presses, such as: Holes, Slots, Miters, Perforating, Shear Forms, End Fabricating, & Cutouts. Inline Embossing and Ring Bending including cutoff is also accomplished. This is a further reason Roll Formed Angles can be a less expensive option. Tolerances on dimensions are much more accurate than you may receive with Press Brake Forming and at volumes over 1,000 feet, roll formed angles can be less expensive by the faster production that's possible.

All metals are used to make Roll Formed Angles: Steel, Stainless, Alloys, Aluminum, Brass, Copper, Bronze, High Strength Tensile & Yield, Foil, Clad, Perforated, Wire Cloth, Galvanized & Embossed. Prefinishes used are: Prepainted, Preplated, Galvanized-(G30, G60, G90, G210, Electro, Bonderized), Prepolished, Strippable PVC Coating, Prelaquered, Prelaminated Vinyl, Aluminized, Galvanneal, Galvalume.

Uses of Angles are as varied as there are industries that use them. Framing is one of the largest usages but they are also used as: Rails, Posts, Frames, Supports, Hangers, Brackets, Reinforcements, Stiffeners, Flanges, Collars, Trim, & Bars.
