HVAC & plumbing sheet metal for Raleigh contractors

Raleigh's construction boom runs on tight schedules, and SWI Sheet Metal keeps Wake County contractors supplied with SMACNA-compliant ductwork on a daily truck route from our Charlotte shop. From RTP tech campuses to downtown high-rises, our metal is in the ceilings of the Triangle's biggest projects.

Every Raleigh order is fabricated to print, labeled by job, floor and system, and shrink-wrapped for clean jobsite delivery. Spiral pipe, rectangular TDF duct, roof curbs and welded exhaust all ship together so your crews never wait on a second supplier.

What we fabricate for Raleigh contractors

Every order headed to a Raleigh 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 Raleigh 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 Raleigh 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 Raleigh job.
