What we fabricate for Durham contractors

Every order headed to a Durham jobsite is fabricated at SWI's Charlotte shop to the same SMACNA standards our contractors have trusted since 1966 — then labeled by job, floor and system before it ever leaves the dock. Our Durham customers order the full commercial package:

• Rectangular Ductwork

  SMACNA-compliant rectangular duct fabricated on automated coil lines. TDF/TDC flanged connections, 26–20 gauge galvanized, lined or unlined, sealed to SMACNA Seal Class A.

• Spiral Pipe & Fittings

  Spiral lock-seam round and flat-oval pipe with matching elbows, tees, reducers and taps. Gored, stamped or radiused fittings to spec for exposed architectural ceilings.

• Black Iron & Grease Duct

  Heavy-gauge welded black iron duct for kitchen exhaust, industrial exhaust and smoke control. Continuous welded seams, NFPA 96 compliant for commercial kitchen grease duct.

• Drain Pans & Plumbing Metal

  Custom condensate drain pans, water heater pans and plumbing sheet metal built to your dimensions. Soldered or welded corners, PVC or threaded drain connections.

• Roof Curbs & Flashing

  Equipment roof curbs, curb adapters, pitch pockets and counter flashing fabricated to RTU submittals. Fully welded and reinforced for carrier and package units.

• Custom Fittings & Specialty

  Transitions, offsets, elbows, boots, collars, wyes and one-off specialty sheet metal. Send a sketch or a CAD file — our shop builds it to the print, labeled by job and floor.

Contractors across Durham and greater North Carolina choose SWI because the estimate comes back within one business day, the metal arrives within 24–48 hours, and the driver already knows the route. Whether your project calls for standard rectangular duct or a one-off stainless transition, send your prints today and put 60 years of fabrication experience on your next Durham job.
