Ducting (HVAC Ductwork)
AUS Sheet Metal specialises in the fabrication and installation of high-quality ductwork for commercial ventilation & exhaust systems. We manufacture a wide range of ducting—including supply air, return air, and exhaust ductwork—custom-built to suit each project’s mechanical and architectural requirements.
All ductwork is fabricated in-house using premium materials*to ensure durability, airflow efficiency, and long-term performance. Whether for kitchen ventilation, HVAC systems, or complete air circulation setups, our ducting is designed to integrate seamlessly with canopy systems and meet all relevant AS/NZS standard.
Our team works directly from mechanical engineer drawings, ensuring accuracy and compliance at every stage. From design through to installation, we deliver ductwork solutions that are precise, reliable, and tailored to the needs of commercial kitchens and large-scale facilities.

Ducting Solutions by AUS SHEET METAL
Ducting systems are engineered networks of ducts that channel air for heating, ventilation, and exhaust in commercial buildings. AUS SHEET METAL, based in Victoria, is a trusted manufacturer and installer of custom ducting systems across Australia. From stainless steel ducting to galvanized HVAC ductwork, and from commercial kitchen ducting to heavy-duty exhaust duct systems, our expertise covers the full range of ventilation needs. These systems ensure efficient airflow and temperature control while safely removing smoke, grease, or other pollutants. Well-sealed duct systems prevent air leakage and pressure loss, maximizing airflow and improving energy efficiency. For projects ranging from restaurants and schools to hospitals and factories, reliable ducting is crucial for safety, energy efficiency, and occupant comfort. AUS SHEET METAL manufactures high-quality ductwork in-house for commercial ventilation, HVAC and exhaust applications. We use premium-grade materials to achieve durability and performance. Our designs integrate seamlessly with kitchen canopies and ventilation systems, and are built to meet all relevant AS/NZS standards.
Types of Ducting and Materials
Ducts are typically constructed from materials like galvanized steel or stainless steel. AUS SHEET METAL uses premium-grade materials to ensure durability, longevity, and performance.
Stainless Steel Ducting
Stainless steel ducting is ideal for corrosive or hygienic applications, such as commercial kitchens or food processing facilities. Stainless steel resists corrosion far better than galvanized steel and offers superior strength. Its smooth, non-porous surface is easy to clean and meets strict hygiene and fire safety standards. Stainless ducting is commonly used in grease extraction and exhaust duct systems where durability under heat and moisture is essential.
Galvanized Steel Ductwork
Galvanized ducting is coated with zinc for rust protection and is a cost-effective choice for general HVAC ventilation. The zinc coating shields the underlying steel from oxidation, helping to prevent rust. This makes galvanized ducts suitable for typical air supply and return systems. However, in humid or corrosive environments, stainless steel is preferred for its superior longevity.
Applications of Ducting Systems
AUS SHEET METAL supplies ducting solutions for a variety of commercial and industrial applications:
HVAC Ductwork: We design and fabricate duct systems for heating, ventilation, and air conditioning. These systems distribute conditioned air throughout buildings, maintaining comfort and air quality. Our in-house fabrication ensures precise fitment to engineered drawings, delivering accurate and reliable airflow control.
Commercial Kitchen Ducting: In restaurant and industrial kitchen ventilation, ducting connects exhaust hoods to fans and vents. Properly designed kitchen ducting captures smoke, steam, and grease-laden air, directing it safely outdoors. AUS SHEET METAL’s kitchen duct systems comply with AS/NZS 1668.2 for ventilation safety and hygiene.
Industrial Exhaust Systems: Factories, workshops, and laboratories often require exhaust ducting to remove fumes, dust, or heat. Our exhaust duct solutions use robust materials and custom layouts to handle heavy-duty extraction needs. Each system is engineered to meet relevant AS/NZS and safety standards.

Engineering Integration: For complex projects, our engineering team provides design support to ensure ductwork integrates seamlessly with broader HVAC and fire-safety systems.
Compliance and Standards
Safety and compliance are paramount in ducting design. The Australian National Construction Code (NCC) mandates that both flexible and rigid ductwork conform to the AS/NZS 4254 standard for duct construction and fire performance. Commercial kitchen exhaust systems must meet AS/NZS 1668.2 (2012, updated 2024), which governs ventilation design, fire safety, and air quality in kitchens. Our ducting solutions are engineered to satisfy these codes:
AS/NZS 4254 (Ductwork for Air-Handling): Duct materials and assembly are tested for fire performance as required by the NCC.
AS 1668.2:2024 (Ventilation in Buildings): The updated standard provides guidelines for mechanical ventilation, ensuring systems support indoor air quality and energy efficiency.
AS 1668.1 (Smoke Control): Duct systems in fire compartments (such as kitchen exhaust shafts) are designed to comply with smoke-control requirements.
AS 1851 (Fire Maintenance): Routine maintenance schedules (e.g. filter cleaning and inspections) are followed to meet Australian fire safety standards.
By adhering to these standards, AUS SHEET METAL ensures each installation is safe, efficient, and compliant. Our materials and design processes deliver long-term performance, reducing health and fire risks in commercial settings.
