Laser Cutting Thickness Chart
Understand realistic cutting ranges for HVAC duct sheet thicknesses and how to match laser power to 0.5–2 mm galvanized and stainless sheet.
CNC Machines for HVAC Duct Manufacturing
Sheet metal cutting and forming for HVAC ducts, ventilation components, fittings and ductwork. Efficient fabrication for ventilation and air handling equipment.
Industry Overview
What is this application about?
HVAC duct manufacturing involves duct sections, fittings, flanges and ventilation components. Sheet metal fabrication is used for cutting sheet to size, notching and forming bends for duct assembly. Materials are typically galvanised or stainless sheet in the 0.5–2 mm range. Production can be batch or higher volume; CNC bending and cutting provide consistent dimensions and support efficient fabrication of duct and fitting parts.
Different duct sizes and fitting types require different part dimensions and bend configurations. CNC press brakes and fiber laser cutting machines support flexible production for HVAC ductwork.
Fabrication Requirements
Common Fabrication Requirements
Bending for duct sections and flanges
Duct sections, fittings and flanges require consistent bend angles for proper assembly and sealing.
Cutting and notching sheet for assembly
Fiber laser cutting accurately cuts and notches sheet for duct assembly without secondary processing.
Repeatable dimensions for duct fit
Consistent part dimensions ensure that ducts and fittings fit together properly during installation.
Efficient production for batch orders
Batch duct production benefits from stable CNC processes that maintain quality across repeated orders.
Core Machines
Recommended Machines
CNC press brakes are used for bending duct sections, fittings and flanges with repeatable angles. Fiber laser cutting machines cut and notch sheet for ducts and fittings. Shearing machines suit straight cutting where laser is not required. Equipment is selected to match sheet size, thickness and production volume.

Machine Routes
Recommended Production Routes
Choose a machine path based on your product range
HVAC duct fabrication includes rectangular and round ducts, fittings and custom ventilation components. The machine combination depends on duct size, material thickness and production volume.
Standard Rectangular Duct Production
Most CommonBest for: HVAC ductwork manufacturers and sheet metal workshops producing rectangular ducts, fittings and standard ventilation components.
Fiber Laser + CNC Press Brake + Shearing
Fiber laser handles duct blanks, notches and fitting cutouts. Press brake forms flanges and fittings. Shearing preps straight blanks for rectangular ducts efficiently.
Custom and Complex Duct Fabrication
FlexibleBest for: Fabricators producing custom duct shapes, complex fittings and non-standard ventilation components for specialised projects.
Fiber Laser + CNC Press Brake
Fiber laser handles complex contours and fitting shapes. Press brake covers custom bends and flanges. Practical combination for flexible, lower-volume custom work.
For HVAC duct in 0.5–2 mm galvanised or stainless sheet, a practical fiber laser and press brake combination handles most rectangular and fitting duct requirements.

Process
Typical Production Workflow
- 1
Cutting and notching sheet
Sheet is cut and notched using laser or shear, preparing blanks for duct and fitting assembly.
- 2
Bending on press brake
Duct sections and flanges are bent on CNC press brakes to required angles for proper assembly.
- 3
Assembly
Duct parts are assembled using seaming, welding or other joining methods.
Laser cutting and press brake bending form the core CNC steps for HVAC duct fabrication.

FAQ
FAQ
HVAC duct and ventilation production typically uses CNC press brakes for bending duct sections, fittings and flanges, and fiber laser cutting or shearing for cutting sheet to size. Galvanised and stainless sheet are common; thickness often ranges from 0.5 mm to 2 mm. Laser cutting handles contours and notches; press brakes form bends for duct sections and connection flanges.
Yes. Fiber laser cutting is widely used for duct blanks, fittings and connector parts. It cuts thin to medium gauge sheet accurately and handles notches and patterns needed for duct assembly. Table size and power are chosen to match sheet size and thickness. Shearing is also used where only straight cutting is needed.
Consider maximum sheet length (duct and fitting dimensions), material thickness (often 0.5–2 mm) and bend complexity. Tonnage and bed length should match your largest part. CNC control supports repeatable bends for duct sections and flanges. We can recommend a press brake configuration based on your part mix and volume.
Duct and fitting sheet is often 0.5–1.5 mm for standard ducts and 1–2 mm for heavier sections or fittings. CNC press brakes and fiber laser cutting machines in standard ranges cover these thicknesses; exact capacity depends on machine specification.
