Trusted by the trades for 60 years
SWI has fabricated every major duct package we've installed for twenty years. The labeling system alone saves my crews a full day on big jobs.

Quotes come back fast, the metal is always to spec, and their drivers know every jobsite in the Triangle. They run like an extension of our own shop.

We had a 48-hour emergency turn on welded grease duct in Greenville. SWI made the truck. That's why they've had our business for three decades.
