Kavanagh Industries supplies mechanical ductwork systems designed to integrate seamlessly with HVAC infrastructure, air handling units, and large-scale mechanical services. Built for reliability and performance, our ductwork supports airflow, pressure control, and system efficiency across commercial, industrial, and institutional buildings.
With in-house design, fabrication, and delivery coordination, we make it easier to get mechanical ductwork delivered, installed, and working on schedule.
Engineered for Mechanical Systems
We manufacture and supply ducts and HVAC ducts that promote steady air flow, enabling consistent cool air delivery from your air conditioner to each zone. We manufacture ducting built to meet these demands with precision and efficiency.
We supply mechanical ductwork for:
- Commercial buildings and office fit-outs
- Industrial facilities and processing plants
- Hospitals and healthcare buildings
- Shopping centres and retail precincts
- Education, defence, and government projects
Our systems support:
- Air handling units (AHUs) in hospitals and commercial buildings
- Fan coil units (FCUs) in apartment towers or office fit-outs
- Chilled beam systems for temperature-controlled environments
- Packaged rooftop units (RTUs) in retail and light commercial
- Mechanical risers in multi-level buildings
- Building management systems (BMS) for airflow monitoring and regulation
Built to Match Project Specifications
Our mechanical ducting is designed to meet system specifications and building service requirements across a wide range of applications.

We fabricate using high-quality materials suited to mechanical systems:
- Galvanised steel
- Stainless steel (various grades)
- Aluminium
- Fire- and corrosion-resistant coatings
We source locally where possible, including Australian-made Bluescope steel for galvanised and coated applications. Materials are selected based on airflow rate, duct routing, temperature range, and exposure conditions. Every component is fabricated for long-term reliability, ease of air duct installation, and system efficiency.
Our ductwork features:
- Welded and sealed joins
- Flanged ends and joint reinforcements
- Accurate internal shaping for airflow consistency
- Fire-rated and acoustic options available
We manufacture all common and custom components, including:
- Straights, elbows, reducers, and branches
- Transition pieces, plenum boxes, and hoods
- Access doors, dampers, and fan connections
- Mounting brackets, vibration isolators, and seals
We also supply brackets, clamps, and fittings as needed to support system stability and ease of installation. Our metal ducts are fabricated to reduce air duct wear over time. We use precise joint construction and gasketed flanges for sealing ducts, helping to prevent bad air duct seals that can affect performance and efficiency.
Trusted by Mechanical Contractors
- Mechanical installations often involve tight timeframes, multi-service coordination, and strict quality checks. Our team works with mechanical contractors, builders, and engineers to provide practical, reliable ducting solutions.
- Proven on Projects Across Australia: Our mechanical ducting is installed across hospitals, data centres, commercial towers, education precincts, and large industrial sites.
- Support That Adds Value: We assist with air duct layout, material selection, pressure class, and installation access, helping you deliver on time and on budget.
- Clear Coordination: We work directly with your estimators, project managers, or installation teams to align on specs, staging, and deliveries, helping reduce future HVAC ductwork installation problems.
Common Mechanical System Challenges Solved by Quality Ductwork
Poorly fabricated or installed ducting can cause delays, inefficiencies, and compliance issues. Our systems are designed to help mitigate:
- Pressure loss and airflow imbalance
- Loud noise caused by vibration or poor sealing
- Excessive wear from improper air velocity or material mismatch
- Energy waste from leaky or undersized ducts
- Difficulties in accessing and maintaining ductwork once installed
By manufacturing ducting that fits properly, performs consistently, and lasts longer, we help avoid these common issues across mechanical projects.
Compliant and Quality-Controlled
Each ducting system is fabricated in accordance with project drawings and relevant mechanical and air handling standards. We maintain full traceability on materials and provide detailed documentation to support signoff and commissioning.
Each system is inspected to ensure there are no leaks, which can lead to pressure issues and low indoor air quality. Orders are fully documented to assist with compliance, certification, and future reference.
Efficient, Serviceable, and Built to Last
Our mechanical ducting systems are built with real-world conditions in mind. We focus on air leakage prevention through sealed joints, straightforward access for inspection and cleaning, and smooth internal finishes that reduce friction and resist build-up. Proper sealing of ducts is critical for system balance and maintaining good indoor air quality across commercial and industrial settings.
Each component is accurately sized and laid out to help maintain system balance. From high-pressure delivery to low-velocity exhaust, our ductwork is made to perform reliably.
Built for Scale, Delivered with Precision
- Kavanagh Industries can handle small, medium, and large-scale mechanical ductwork packages with precision staging and fast turnaround times. Our logistics team ensures every delivery is coordinated and installation-ready.We provide:
- 1-week standard lead times
- 24-hour fast-track options (where applicable)
- Clearly labelled and packaged ductwork matched to site plans
- GPS-tracked fleet and lifting equipment for site access
