Custom Duct Fabrication
We create precision-engineered duct systems tailored to project specifications using galvanized sheet metal, aluminum, copper, and stainless steel. Our fabrication adheres to industry standards while accommodating unique requirements. Clients benefit from reduced material waste, faster installation, and seamless assembly support with ID tracking.
TDF Duct Systems
Our TDF systems use roll-formed sealable flanges with snap-on corners that eliminate spot welding. This method allows thinner gauges for weight reduction while maintaining structural integrity. Customers gain faster floor assembly and easier transport compared to traditional duct systems.
Slip & Drive Ductwork
We produce slip & drive duct connections meeting SMACNA standards for commercial HVAC applications. This common system uses cleatbenders and drive turns for secure assembly. Clients receive reliable solutions suitable for low and medium-pressure environments with widespread industry compatibility.
Metal Supply Services
