How Custom Sheet Metal Is Used to Make Air Ducts
Creating custom ductwork out of sheet metal is a process that can either be done primarily with hydraulic machinery, or through a handmade process that requires minimal help from heavy equipment. Proper ducting is a key part in an HVAC system that runs safely and efficiently, which is why hiring professionals with expertise in custom metal fabrication is a key component in developing an effective HVAC structure. Although the handmade process requires more patience and effort, both methods have the ability to produce ideal results.
Custom sheet metal ductwork that is done primarily by hand still requires a good amount of materials and tools. For clean cuts, minimal deformation, and optimal bending, laborers will need:
- swing beam shears
- galvanized sheet metal
- a professional plate roller
Prior to the sheet metal being fed into the roller, the swing beam sheers are used to cut each section into the custom lengths necessary for creating the pockets and extensions for each duct. Each corner should be notched by a notching tool in order to form a click-and-lock system that will allow the straight trunk ductwork to lock into place later on.
After the Plate Roller or Hydraulic Press Brake Is Utilized
Whether the galvanized sheet metal is fed into a plate roller during the handmade process, or fed into a hydraulic press brake at a metal fabrication facility, it will need to be fastened together on a fabrication bench. The lock joint should then be finished at a 90 degree angle. Laborers can slightly bend the sheet with a wide manual break beforehand if they feel that it is necessary.
Installing a duct system that meets the custom specifications of each HVAC setup should be a primary concern for any commercial or residential consumer. When the ductwork in a building’s HVAC system is subpar, energy costs immediately reflect the lack of efficiency present within the structure itself. Recruiting professionals who have extensive knowledge in custom sheet metal ductwork will provide you with an HVAC setup that is both cost-effective and energy efficient.
