Edge quality & fit-up: Cleaner edges than plasma/shear for TDC/TDF flanges, seams, and cleats; less downstream deburr.

Flexible automation: Coil-fed and FMS lines (e.g., laser blanking from coil) let you run nested duct parts lights-out, integrate label/marking, and reduce WIP. 

Digital workflows: CAD→CAM→nesting with SMACNA rules (allowances for hems/notches) minimizes scrap versus turret/punch programs.

Airflow efficiency – Designed to minimize turbulence and pressure drop.

Leakage control – Proper sealing with gaskets, tapes, or sealants ensures energy efficiency.

Noise & vibration control – Acoustic linings, flexible connectors, or fabric ducts reduce sound.

Thermal insulation – Insulated panels and wrap reduce heat loss/gain and condensation.

Fire & smoke resistance – Materials rated to NFPA/UL standards where safety is critical.
