What gauge should 16" galvanized round duct be?

For a 16-inch galvanized round duct, the appropriate gauge is #28 gauge. The gauge number refers to the thickness of the metal used in the ductwork, and it's crucial to select the right gauge to ensure proper airflow, durability, and ease of installation.

In the case of galvanized round ductwork, #28 gauge is commonly used for ducts of this diameter. This gauge provides a balance of strength and weight, which is important for maintaining structural integrity during installation and throughout the ductwork's operational life. Using a gauge that is too thin could lead to problems such as deformation or insufficient durability, while a gauge that is too thick may be unnecessarily heavy or more difficult to work with.

Understanding the standard for duct gauges is vital in HVAC installation, as it ensures that the ductwork will perform efficiently and effectively under various conditions.
