Machine to work oblong metal products, including a drawing apparatus to feed at least one of said metal products in a direction of feed and a work apparatus aligned in said direction of feed. The drawing apparatus includes a first drawing unit and a second drawing unit opposite each other with respect to said direction of feed. The first drawing unit and the second drawing unit define between them, in said direction of feed, a drawing channel for the at least one metal product. The drawing channel has a lying plane, defined by a plurality of anchoring inserts, for the at least one metal product, a supply apparatus being possibly present upstream of said drawing apparatus.

A method utilizing an automated bending machine to bend Z-bar into a circular configuration for use as a fire pit ring or other structure. Z-bar has the desired cross-section such that when it is rolled into a circular configuration, it features a vertical intermediate section, an upper lip extending outward from said vertical intermediate section and lower lip extending inward from said vertical intermediate section. The upper lower serves to hold the fire pit ring in a support structure while the lower lip serves to hold a fire pit container.
