One of the specialized pieces of equipment at Zeyon is a 4‑roll plate roller. This piece of equipment can roll pieces of metal into round and conical shapes. Plate rolling also goes by plate rolling, plate bending, or roll bending. A 4‑roll plate roller makes the bending process simpler than with 2- and 3‑roll plate rollers. They make it possible to prebend both plate ends without removing the piece, which is required by single-pinch rollers.
