The pierce-rolling process, which was patented in 1886, made it possible for the first time to roll a thick-walled seamless hollow body from a solid steel billet.. To do this, the billet is heated to between 1200 and 1300°C and then positioned between two rolls arranged at an angle to each other and operating in the same direction, thus locking the billet into a kind of gear mechanism.

Metal extrusion tends to produce an elongated grain structure, usually considered favorable, in the part's material in the direction that the work is extruded. Extrusion, in many instances, can be considered a semi continuous manufacturing operation. Continuous because the process will manufacture a continuous length of the same cross section.
