HVAC Square Ductwork Machinery is a range of industrial equipment used for the making of rectangular air duct systems for modern ventilation and air conditioning (HVAC) applications.
StanGroup Liberty Seamless Machinery provides equipment that is used in the making and manufacturing of duct components — from forming and cutting sheet metal to assembling, reinforcing, and finishing rectangular duct sections. A rectangular duct machine is typically used as one stage in this workflow, enabling precise fabrication of square and rectangular ventilation channels.
The equipment in this category is supplied and supported by StanGroup Liberty Seamless Machinery, specializing in industrial HVAC duct production solutions and sheet metal forming systems.
Types of Machines Used in HVAC Duct Production
- Pittsburgh Lockformer Machines – for forming duct connection locks (Pittsburgh, standing seam, hem, C-lock, Z-lock)
- TDFC / TDC Flange Forming Machines – for producing standardized duct flanges and cleats
- Flange Roll Forming Machines (TDFC TDCF systems) – for automated flange and cleat production
- Standing S Cleat Roll Forming Machines – for reinforced heavy-duty duct connections
- Pneumatic TDFC Sheet Metal Brake Machines – for bending and assembling duct boxes and fittings
- TDFC Corner Fixing Machines – for inserting and crimping duct corners in flange systems
- Square Duct Beading Machines – for adding reinforcement beads to increase duct rigidity
- Portable Seam Closing Machines – for sealing Pittsburgh lock seams on duct sections
Together, these machines are used at different stages of HVAC duct fabrication, allowing efficient production of air distribution components with high precision and repeatability. In modern workshops, they are combined into flexible production workflows depending on project requirements.
Applications
StanGroup Liberty Seamless Machinery equipment is widely used in HVAC duct fabrication workshops, ventilation system manufacturing plants, sheet metal processing factories, and construction supply production facilities. A typical hvac duct manufacturing machines setup is used in the making and manufacturing of ducting for air conditioning, ventilation, smoke extraction, and industrial airflow systems.
