Our Custom Ductwork Fabrication Process

Hennemuth stocks pipes in 10-foot lengths in even sizes from 4- to 24-inch diameters. We also stock fittings in even sizes from 4- to 24-inch diameters, including saddle taps, reducers, 90 elbow, 45 elbow, couplers and end caps. Our team manufactures pipe and fittings up to 30 inches in diameter. Other fitting sizes can be made to order, and custom-length pipe is available.

Whatever the project is, our team is here to manufacture ducts that will work for any space. Although we already offer an extensive range of sizes and duct options, we understand every project differs. We can create tailored parts in our in-house manufacturing facility to ensure we provide the most effective HVAC products for every job.

Our team will review any project photos or blueprints before deciding on the right custom ductwork design and fabrication process. During a consultation, you can review our standard duct fabrication options, including spiral and rectangular ducts, giving our team an existing product to reference before creating a unique design.

Each team member is knowledgeable and skilled in our custom duct fabrication process — we can provide an accurate project timeline and estimate before creating a personalized design.
