Expertly fabricated ductwork supports efficient air, reliable HVAC performance and code compliance. It helps systems run better, saves energy and keeps installations on track.
Hennemuth Metal Fabricators is a trusted HVAC distributor in Pittsburgh that understands the importance of precision and the value of service. We build standard and custom ducts and fittings for residential and commercial projects.
Our Ductwork Products
As a premier ductwork manufacturer, we have various materials that will fit any HVAC system. Our options come in different sizes, shapes and designs with various features to match any existing ductwork. Our selection lets you easily pick a style that matches your preferences or project needs.
Our comprehensive product range optimizes our ability to find a part to fit any existing HVAC system. We also have numerous HVAC ducts to improve the convenience of the process, as our offerings allow you to purchase a part that will enhance a current system or create one from start to finish.
Rectangular Ducts
Rectangular ducts maximize space efficiency and simplify installation, ensuring strong airflow and system performance. We offer standard and custom rectangular metal ductwork for residential and commercial HVAC systems, including double-wall ducts in various sizes and metals.
Our design team works closely with you to optimize layouts and reduce costs. Made from durable materials and fabricated to precise specs, our ducts fit tight spaces, minimize air leakage and ensure efficient airflow.
Spiral Ducts
At Hennemuth, we manufacture spiral HVAC ducts in galvanized, galvanneal (Paint Grip), stainless steel and double-beaded steel — available in 4 inches to 40 inches. Standard lengths are 10 feet, with custom cuts up to 20 feet. Powder coating and insulation up to 2 inches thick are also available.
Our facility fabricates gasketed or flanged fittings, all meeting or exceeding Sheet Metal and Air Conditioning Contractors’ National Association (SMACNA) standards. Spiral ducts reduce leakage and noise while enabling easy insulation and cleaning.
Flex Ducts
Flexible ductwork is key in HVAC systems, especially for trunk-and-branch setups or tight spaces. At Hennemuth, we supply UL-listed flexible ducts in 25-foot lengths (cut to size) to ductwork contractors across Pittsburgh and surrounding areas.
Options include uninsulated foil flex and insulated ducts in R4.2, R6 and R8 values. Available in 4- to 20-inch diameters, our products feature reinforced vapor barriers, two-ply inner cores and durable helix constructions. We also source specialty ducts — acoustic, high-pressure and antimicrobial — for commercial use.
Custom Ductwork Fabrication
When off-the-shelf ductwork will not cut it, we build exactly what your project demands. We custom fabricate to spec, offering options like internal lining (½-inch or 1-inch insulation), external wrapping, Slip and Drive, four-bolt rectangular connectors, Pittsburgh Duct and Snap Lock Duct.
Our team designs duct runs, recommends time-saving alternatives and ensures every piece fits your system, new or existing. With decades of experience, if you can draw it, we can build it.
Fittings and Connectors
We supply a full range of duct pipe fittings and couplings, with custom fabrication available for unique project needs. We stock rectangular, spiral and flexible connectors, plus saddle taps, elbows, boots and more. Our team reviews project specs, blueprints and photos to ensure the best fit and finish.
With in-house manufacturing, SMACNA-compliant designs and decades of experience, we help HVAC professionals meet deadlines without compromising quality or performance.
