Widely used across the HVAC industry, galvanised and stainless steel ductwork is known for its structural integrity. Once installed, it minimises issues such as sagging, warping, or physical degradation under pressure.
- Sheet metal ductwork is fabricated to match the project’s design drawings. This ensures accurate alignment, consistent joints, and reduced need for adjustments during installation.
Properly sealed seams help minimise air leakage throughout the system. This contributes to more reliable airflow and lower energy consumption, particularly in larger systems.
Sheet metal ducting are manufactured to align with recognised Australian standards. This makes it suitable for projects requiring documented compliance or third-party inspections.
Sheet metal maintains its shape and performance with minimal upkeep. This can minimise the frequency of repairs or replacements over the system’s life cycle.
In applications where performance and reliability are essential, sheet metal offers a dependable solution. It manages temperature extremes, airflow pressures, and hygiene requirements with consistency.
Kavanagh Industries operates a state-of-the-art sheet metal fabrication facility equipped for high-volume and high-precision manufacturing:
- Cutting: Laser cutting, shearing, insulation cutting, router cutting
- Forming: Sheet metal roll forming, press braking, Vicon full-length straight duct coil line
- Joining: Pittsburgh and Snaplock longitudinal seams, TDF connectors, MIG, spot, and robotic welding
- Assembly: Subducts, heavy-gauge ductwork (up to 10mm), modular and self-assembly frame systems
- Finishing: Deburring, sealing (fully sealed ductwork for airtight performance)
We specialise in complex geometries, tight tolerances, and reliable, repeatable production for every duct system.
We only work with high-quality materials, including:
- Galvanised steel
- Stainless steel
- Aluminium
- Ductboard (for insulated applications)
- Specialty alloys (for heavy fabrication)
Our ductwork is custom-made and compliant with AS 4254.2.
We fabricate a wide range of sheet metal duct products:
- HVAC ductwork: Supply air, return air, kitchen exhaust, carpark exhaust, stair pressurisation, make-up air, smoke exhaust, garbage exhaust, and clean rooms.
- Construction/Industrial: Structural frames, support systems, plinths, security grilles, and subducts.
- Ventilation and Mechanical: Commercial kitchen exhaust, industrial ventilation, and high-pressure systems (up to 2500PA).
All ductwork is manufactured in full continuity, colour-coded, labelled, and matched with marked drawings so they can be installed with minimal delay and fewer adjustments on site.
We manufacture to client-supplied drawings, but our team is on hand to assist with:
- In house design support
- Tender support and estimating
- Fully costed 3D models and BOMs
- Fast-tracked prototyping for urgent projects
