Machinery and Equipment:
Mestek Machinery rollforming machinery — engineered and manufactured through our Lockformer and Engel brands — was designed to meet the needs of today’s HVAC duct manufacturing industry and represents the global benchmark for precision, high-speed production, and long-term durability in sheet metal shops. Our comprehensive line-up covers the full range of industry-standard HVAC duct flange connector profiles and other specialty applications such as notching, cleat forming, and collars.
Lockformer has been the most recognized name in the sheet metal machinery industry and has led the world in the production of HVAC roll forming equipment since 1938. The Lockformer Transverse Duct Connector (TDC) T25a Rollformers are still the only transverse duct connector machines on the market that produce rollformed flanges certified to have passed all the functional criteria tests from 1/2″ – 10″ water gauge to comply with SMACNA Duct Construction Standard (DCS) T-25a. This same exacting standard for quality carries through the other rollformers in the line for Pittsburgh Lock, Slip-and-Drive, Button-Punch Snap-Lock, and other specialty flange profiles.
Since 1948, the Engel brand has produced practical, cost-efficient roll forming machinery specifically for HVAC sheet metal duct fabrication. The Engel Transverse Duct Flange (TDF) T25B Rollformers are the only transverse duct flange machines on the market certified to comply with SMACNA Duct Construction Standard (DCS) T-25b based on actual laboratory tests across the full range of water gauges. This same cost-effective approach extends to our other Engel rollformers designed for HVAC industry-standard profiles — Pittsburgh Lock, Slip-and-Drive, and Button-Punch Snap-Lock.
