What gauge of galvanized steel is specified for clothes dryer ducts?

The specified gauge of galvanized steel for clothes dryer ducts is indeed 28 gauge. This is important for ensuring that the material is sturdy enough to handle the temperature and pressure changes that occur during operation. The 28 gauge provides adequate strength and durability, helping to prevent issues such as duct collapse or damage from lint buildup over time.

Additionally, using 28 gauge steel helps to minimize fire hazards, ensuring the dryer operates safely by allowing for proper venting of air and moisture. Thinner gauges, such as 30 or 32, may not offer the same level of structural integrity and could lead to compromised performance or safety concerns. On the other hand, while 26 gauge would be stronger, it may not be necessary for residential applications, emphasizing the importance of using a gauge that balances strength with practicality in dryer duct installations.
