Galvanized ductwork systems
Low- and high-pressure galvanized duct fabricated to SMACNA standards and sized to your drawings — or to ours, if we're doing the design too.
Service
Metal Fabrication
A full sheet-metal fabrication shop inside your mechanical contractor. Low- and high-pressure ductwork, welded grease duct, roof curbs, exhaust hoods, and custom work — cut, formed, welded, and installed by the same Asheville team. R&W has fabricated in-house since 1958.
Specialties
If it's sheet metal, our shop builds it.
What leaves our London Road shop goes straight onto our trucks and into your building — no third-party fabricator, no freight delay, no finger-pointing when a fitting doesn't fit.
Aluminum & stainless ductwork
Specialty metals for corrosive, washdown, coastal-grade, and architectural applications — fabricated with the same precision as our galvanized work.
Welded grease duct
Continuous-weld kitchen grease duct built to NFPA 96 — the backbone of every commercial kitchen exhaust system we install.
Roof curbs & adapter curbs
Custom and adapter curbs that match a new rooftop unit to an existing roof opening — change out the equipment without re-working the roof.
Exhaust hoods
Kitchen exhaust hoods fabricated and installed as a system — hood, welded grease duct, make-up air, and fire-marshal coordination.
Ventilation, exhaust & installation
Complete ventilation and exhaust systems — and our own installers hang what our shop builds, so the fabrication and the field never argue.
The Shop
Equipment most contractors have to outsource to.
When the fabrication shop is in-house, lead times shrink from weeks to days, change orders don't stall the schedule, and a field measurement turns into a finished fitting without leaving the company.
Our Asheville shop runs the full line — automated plasma cutting, power press brakes, rollers, and dedicated duct machinery — staffed by fabricators who've been building western North Carolina's ductwork for decades.
