Zimmerman Metals, Denver, offers a commercial roof panel machine with a patented material handling system. The independent drive system is always centered on the panel coupled with free spinning forming rollers, which minimizes oil canning and potential adjustments. Multiple panels can be run in any width from 12 to 24 inches. The machine forms 1 3/4-inch snap lock or 2-inch mechanically seamed profiles. The advanced design allows tooling changeover in approximately one hour. It has an industrial-grade hydraulic system with an 18-gallon stainless-steel tank.
