Sheet metal ductwork fabrication
- Hand cutting and folding: This is the traditional method where sheet metal (typically galvanized steel or aluminum) is measured, cut using tin snips or shears, and then folded into shape using manual bending tools and hammers.
- Screwed or riveted assembly: Sections of sheet metal are cut to size and assembled by screwing or riveting together. This method requires precise measurement and alignment to ensure tight seams.
- Automated cutting and folding: Modern fabrication shops use computer-controlled machines (CNC) for precise cutting and folding of sheet metal based on CAD drawings. This method is efficient and allows for complex designs with minimal human error.
Fiberglass duct board fabrication
- Fiberglass duct board is a lightweight and insulated material used for ductwork, typically cut using special knives or saws designed for fiberglass. Pieces are assembled using special adhesives and tapes, ensuring airtight joints.
Flexible ductwork fabrication
- Flexible ductwork is often manufactured in pre-formed sections by the supplier. Installation involves cutting to length and connecting to fittings or other duct sections. This method is straightforward and suitable for quick installations in spaces where rigid ductwork is impractical.
Ductile iron pipe fabrication
- For larger HVAC systems or industrial applications, ductile iron pipes are used. Fabrication involves cutting the pipe to size using cutting tools or saws and then welding pieces together using welding techniques suitable for ductile iron.
PVC duct fabrication
- PVC ducts are fabricated by heat forming sections to the required shape and then welding pieces together using PVC welding techniques. This method is commonly used for corrosive or chemical-resistant applications.
Duct insulation fabrication
- Duct insulation is typically applied after duct fabrication, using insulation materials such as fiberglass or foam wrapped around the ductwork and secured using adhesive or mechanical fasteners. This step is especially important for thermal efficiency and condensation control.
