Plates are available in many materials. The most common materials for plates, that are going to be bent, are carbon steel and stainless steel. Plates can be bent using different methods. The most common are rotary compression bending machines, press brakes and roll benders. Press brakes are generally large expensive machines. The tooling is large and expensive. The set up time is extensive. But they have the advantage of being able to bend large plates, up to 120 IN wide. Roll benders are smaller and less expensive. The tooling is less expensive also and the set up time is minimal. They have the advantage of making 360° bends in large plates. They have a disadvantage of not being able to produce small radius bends.
