Cyclomade® manufactures duct systems at our Melbourne facility. Fabrication under one roof supports structural integrity, dimensional accuracy and consistent build quality across commercial and industrial projects.

Cyclomade® duct systems are fabricated using galvanised steel selected for structural performance and durability. Coordinated production processes provide control over material thickness, dimensional tolerances and overall construction quality.
Stock-supported ductwork and standard fittings enable responsive turnaround for common sizes and repeat orders. For larger take-off projects, production scheduling remains aligned with project scope, maintaining consistent build quality across the full works.
Round, rectangular and oval configurations supported by precision fittings and connection components.

Lock-seam galvanised construction manufactured for structural stability and pressure integrity across commercial and industrial ventilation applications.

Comprehensive range of duct fittings and connection components designed for dimensional accuracy and consistent system integration. Custom components are fabricated to suit specific project requirements and take-off schedules.

Rectangular duct systems fabricated for structural stability and controlled airflow performance across commercial and industrial installations.

Space-efficient configuration combining the airflow performance of a round duct with a reduced vertical profile suited to restricted ceiling spaces.
Cyclomade® duct systems are manufactured to support structural stability, pressure integrity and long-term performance across commercial and industrial ventilation applications. Material thickness and construction methods are selected based on diameter, system pressure and project requirements.
Lock-seam construction maintains rigidity over longer spans and reduces joint frequency. Diameters range from 77mm to 1250mm, with galvanised steel thicknesses from 0.6mm to 1.2mm. Standard production lengths are 1 to 4 metres, supporting efficient installation and reduced site joins.
Rectangular systems are fabricated to project-specific dimensions and airflow requirements. Material thickness is matched to application, with Pittsburgh seams and TDF frame options available. Section lengths of up to 1.4 metres are supported by current fabrication capability, allowing flexibility across commercial and industrial installations.
This oval configuration combines the structural characteristics of round construction with a reduced vertical profile suited to low-clearance installations. Manufactured from galvanised steel in 0.8mm and 1.0mm thickness, it maintains airflow efficiency while accommodating architectural and spatial constraints.
Rigid duct systems are manufactured in accordance with AS 4254.2 requirements for metal ductwork in air-handling systems. Construction methods and material selection align with structural and performance requirements relevant to each application.

Cyclomade® duct systems form the structural backbone of commercial and industrial ventilation installations, supporting mechanical engineers and HVAC contractors across diverse project types.
Cyclomade® duct systems are delivered through coordinated estimating, engineering and production processes. Our team works directly from mechanical services drawings and take-off schedules to produce accurately dimensioned duct sections and connection components aligned to project scope.
Custom transitions, complex branch take-offs and project-specific configurations are fabricated to maintain structural stability and system integrity throughout installation.
For projects requiring broader ventilation coordination, additional technical capability is supported through our dedicated Engineering page.


Stock-supported ductwork and standard fittings allow responsive turnaround for common sizes and repeat orders. Coordinated production processes keep scheduling aligned with project requirements across both small-scale supply and larger take-off works.
Material control and fabrication planning are supported by local sourcing and structured production oversight, maintaining consistency across repeat and project-based orders.
AS 4254.2 specifies construction and performance requirements for rigid metal ductwork used in air-handling systems within Australian buildings. It outlines standards relating to materials, structural integrity, sealing methods and fire performance.
Cyclomade® rigid duct systems are manufactured in accordance with AS 4254.2 requirements relevant to metal duct construction.
Yes. Rectangular duct systems are fabricated to project-specific dimensions. Material thickness, seam type and frame selection are matched to application and airflow requirements. Section lengths of up to 1.4 metres are supported by current fabrication capability.
Standard diameter availability ranges from 77mm through to 1250mm, depending on configuration and application requirements. Material thickness is selected based on size and system performance criteria.
Material thickness depends on duct diameter, system pressure and project requirements. For commercial kitchen exhaust systems supplied with Cyclomade® fans, 1.2mm galvanised steel is typically recommended.
Final specification should be confirmed by the project designer, mechanical engineer or certifier in accordance with relevant standards and compliance requirements.
