If your project includes more than spiral ductwork, Hennemuth also fabricates rectangular ductwork, duct fittings and connectors, and commercial ductwork components.
Spiral Duct Materials, Gauges and Finishes
We fabricate spiral ductwork in a variety of materials depending on the project application, environment and specification. Common options include galvanized steel, galvanneal / paint grip steel, stainless steel and aluminum.
Material and gauge selection may depend on pressure requirements, exposure conditions, corrosion concerns, finish preferences and project specifications. Our team can review your drawings, takeoff or materials list and help confirm the appropriate material, gauge and finish for your order.
Common spiral duct options include:
- G90 galvanized spiral duct
- Paint grip spiral duct for projects requiring a matte or paintable finish
- Stainless steel spiral duct for corrosion resistance and demanding environments
- Double-wall spiral duct for applications where insulation or acoustic performance may be needed
- Custom spiral duct fittings, elbows, reducers, couplers, saddle taps and end caps

Benefits of Spiral Ductwork
Spiral ductwork is commonly used in commercial HVAC systems because it offers several performance and installation advantages:
- Efficient airflow: The round shape of spiral duct can reduce turbulence and help air move more efficiently through the system.
- Reduced leakage potential: Spiral duct systems often have fewer seams and tighter connections, which can help reduce air leakage.
- Lower noise: Spiral duct’s rigid construction and lower pressure drop can help reduce system noise when properly designed and installed.
- Clean appearance: Spiral duct is often used in exposed ceiling applications because of its finished, professional look.
- Durable construction: Metal spiral ductwork is strong, long-lasting and suitable for demanding commercial environments.
- Easier maintenance: Round duct can be easier to clean and maintain in many applications.
For projects that require additional components, Hennemuth also fabricates spiral duct fittings, rectangular ductwork and custom commercial ductwork.
Does Spiral Duct Need to Be Insulated?
Spiral duct may or may not need insulation depending on the application, building conditions and project specifications. Insulation is often used when ductwork passes through unconditioned spaces, when condensation control is needed, or when thermal performance and acoustic control are priorities.
In some exposed ceiling applications, single-wall spiral duct may be used without insulation. In other cases, double-wall spiral duct may be preferred because it can provide added insulation value and help reduce noise.
If you are unsure which option is right for your project, send your specifications to Hennemuth and our team can help review the material and insulation requirements.
Spiral Duct Suspension with a Standard Hanger
Manufacturers use steel, chromium and iron to create stainless steel. As iron supports welding operations and can significantly slow down or even reduce corrosion, stainless steel makes excellent ducts. HMF is one of the best stainless steel duct manufacturers, offering stainless steel spiral duct products that are ready for installation. We also provide custom-built stainless steel options. You can offer clients the most durable duct solutions by opting for stainless steel spiral ducts.
People often have questions about hangers for spiral duct, and the reality is that round spiral ductwork works with the same hangers used for typical round ducting. When trying to choose the right spiral ductwork fittings, you can rely on any fitting with the correct shape and weight capability.
Stainless Steel Spiral Ductwork
Stainless steel spiral ductwork is often used in environments where corrosion resistance, durability and cleanability are important. Although stainless steel typically has a higher upfront cost than galvanized steel, it can provide long-term value in demanding applications.
Stainless steel spiral duct may be used in:
- Hot or humid environments
Laboratories and research facilities - Food processing or food service environments
- Industrial ventilation systems
- Applications where corrosive compounds may be present
- Projects where a clean, modern exposed-duct appearance is desired
Hennemuth can fabricate stainless steel spiral duct and related fittings based on your project specifications. Send your drawings, takeoff or parts list to confirm availability, pricing and lead time.
The Advantages of Stainless Steel Spiral Ducts
By utilizing stainless steel spiral ducts, you get:
- Durable ductwork: Stainless steel is more expensive than its counterparts, but this material offers better long-term benefits. You can utilize stainless steel spiral ducts indoors and outdoors without frequent replacements or costly upkeep.
- A healthy environment: Your clients can enjoy healthy, fresh air. Stainless steel is resistant to moisture and condensation and prevents mildew and mold growth. This product is perfect for industries dealing with oil and air mist.
- Corrosion-resistant ducts: Stainless steel ducts can withstand corrosion and are also resistant to absorption.
- Eco-friendly products: Stainless steel spiral ductwork is environmentally friendly and entirely recyclable. Recycled stainless steel is often used to create wave, solar and geothermal power.
- Perfect fitting products: Stainless steel is much easier to work with than aluminum. This material is more rigid, making it possible to fabricate ducts that fit together perfectly. Spiral ductwork manufacturers use it to create custom designs of the highest quality.
- Aesthetically pleasing environments: Your clients will love the sleek and modern look of stainless steel ductwork. Architects and designers can utilize stainless steel applications in food halls and other public spaces.
