The vast variety of metal ring applications extends to clamping, sealing, joining or trimming items such as drums and lids, street signals or mirrors. Children's toys, electronics, vehicles, furniture, appliances and many other products make use of metal rings in some way. A metal ring can be as small as a few inches in diameter or as large as ten feet in diameter.

While metal rings can be made for low-demand applications, certain industrial consumers of metal rings require their rings to meet specific standards of durability, corrosion resistance and other qualities. Chemical producers, oil and gas companies, aerospace products manufacturers, military contractors and other companies that put metal rings to work in demanding applications must be assured that their rings will not fail.

For such applications, steel is often the ring material of choice. Brass, aluminum, copper and zinc are other common materials used in the fabrication of metal rings.

There are a few processes by which metal rings are fabricated. The simplest, least precise way to make a metal ring would be to take a sheet or strip of metal, cut it to size, bend it by hand and weld the edges together. This is hardly a sustainable method because of its inefficiency and imprecision.

Roll forming is the process that most closely approximates the hand-bending method, but it eliminates those inefficiencies. A roll former is a long, narrow machine that features a series of spinning rollers. A long, preprocessed metal strip is fed into the receiving end of the roll former where it is caught by the first set of spinning rollers. These rollers fit tightly around the contours of the metal, and after having drawn the metal in, they push it to the next set of rollers.

Each subsequent set of rollers is configured a slightly different way, and as the metal strip is forced through them, its shape changes. In metal ring roll-forming, the rollers make the metal strip take a circular shape. Because no heat or welding is involved in roll-forming, roll-formed metal rings often emerge in a U shape or a similar shape. For this reason they are generally only suitable for uses in which they can be clamped shut with fasteners or by other means.
