Round Duct

Spiral Ductwork

Precision-formed spiral duct is the workhorse of commercial HVAC. We fabricate to your exact diameter and gauge specifications — from small-diameter branch runs to large-diameter trunk lines. Tight tolerances, clean seams, ready for your installation schedule.

  • All diameters from 4" to 60"
  • Galvanized, stainless, or aluminum
  • Fabricated from hand sketches, shop drawings, or contract sets

Oval ductwork in a low-clearance commercial installation

Space-Saving Profile

Oval Ductwork

When clearance is tight, oval duct delivers the same airflow capacity as round in a lower-profile form. We fabricate oval duct to match your round-equivalent sizing, with the same precision and material options as our spiral line.

  • Equivalent airflow to round duct
  • Ideal for low-clearance installations
  • Matched to your round-equivalent specs
