Capacity: 14 Station, 18 gauge

The machine produces a SMACNA standard T-25a flange. It uses 2.75” of material to produce. The duct wall thickness determines the pressure class rating and the addition of reinforcing rods, which are based on the SMACNA pressure calss charts as well.

As far as mm width of the flange, currently only used for DM35 for ducts requiring a loose flange/frame. A calliper measure was put on a flange off coil line and where it measured 36mm.

The 14 Station Lockformer is a used roll-forming machine designed to handle 18-gauge sheet metal with precision and efficiency. Ideal for HVAC fabrication and custom metal forming applications, this unit features 14 precision-ground stations to produce consistent profiles with minimal variation. With an estimated weight of 4,500 lbs and located in Akron, OH, it’s well-suited for heavy-duty shop environments that demand reliable forming capability.
