The rigid material is also more difficult to carry and place in the right position. As a result, metal ductwork installation is a lot pricier. Flexible ducts are best suited for branching off the main plenum of your HVAC system. silicone molding company They run throughout the building and carry air to individual ceiling vents.

Is round or square duct better?

With less surface area, no corners, and better airflow, round metal duct work eliminates the chances of dirt and bacteria accumulating in the duct

What gauge is most ductwork?

Gage-It Right

The thinnest acceptable sheet metal for ductwork used in a single dwelling is 28 gage or 0.013 and 0.018 inches for galvanized and aluminum, respectively. This measurement is for around duct smaller than 12 inches in diameter and a rectangular section no bigger than 8 inches.

How do you choose duct thickness?

24 gauge is used for the duct size above 300mm to 750 mm and thickness is 0.6mm. 22 gauge is used for the duct size above 750 mm to 1200 mm and thickness is 0.8mm. 20 gauge is used for the duct size above 1200 mm to 3000 mm and thickness is 1mm. 18 gauge is used for the duct size above 3000 mm and thickness is 1.2mm.

Can aluminum be used for ductwork?

Foam ductwork panels are coated with aluminum to prevent moisture and provide a corrosive free system. The coating is dependent upon the operation but can be 80 micrometers to 200 micrometers for outdoor applications. Aluminum ducting is also available insulated or non-insulated from the main duct to the outlet system.

Is 10 gauge or 7 gauge steel stronger?

The rating for steel gauge may seem sheet metal ductwork fabrication backward: the smaller the number, the thicker the steel. 7 gauge steel, for example, is much thicker than 12 gauge steel. And the thickness makes a difference—the thicker the steel, the stronger it is.

Is 20 or 22 gauge steel thicker?

20 gauge is thicker wire than 22 gauge. Thick enough to be bold, but still easy to slip through your piercing. More minimalistic appearance.

What is HVAC sheet metal made of?

Most of the HVAC systems installed by contractors nowadays, including the other parts and ductworks, are commonly made from either aluminum or galvanized steel.

What is HVAC sheet metal?

HVAC sheet metal fabrication is the process that an HVAC contractor goes through to create unique systems for a home or building. By using the fabrication types listed above, HVAC companies can create solutions like rectangular ductwork, spiral ductwork, fittings, roof curbs, and roof curb adapters.
