Mestek Machinery sheet metal benders are designed for the specific needs of HVAC duct fabrication shops. Engineered and manufactured through our Lockformer brand — the most recognized name in the sheet metal machinery industry and the global leader in HVAC roll forming equipment since 1938 — our line-up of benders includes those designed for high-speed folding or bending of drive cleat edges, standing seams, hems, drip edges, s-cleats, right angles, and more. Our Lockformer Button Punch Cheek Bender even serves the dual purpose of bending and punching the cheeks for button punch snap lock 90-degree fittings on one side and bending cheeks for making right-angle flanges for Pittsburgh fittings on the other. Engineered to ensure perfect bends, these machines help maximize productivity in the fittings fabrication operation of any shop.
