Sheet metal shops cut, punch, bend and weld flat stock into enclosures, brackets, panels, chassis and ductwork. They range from HVAC duct shops to precision contract fabricators building for electronics and equipment OEMs, and many run laser cutters, turret punches and press brakes next to welding and powder-coat lines. They buy sheet and coil, cutting and forming machines, welding consumables, finishing services and CAD/CAM software. Purchasing sits with the owner, plant manager or a buyer, and suppliers reach them through distributor reps, trade shows and direct outreach.
