What is the minimum thickness requirement for carbon steel used in duct construction?

The minimum thickness requirement for carbon steel used in duct construction, as specified in the NFPA 96 Standard, is critical to ensure the durability and safety of ventilation systems in commercial cooking operations. A thickness of .054 inches provides adequate strength to support the ductwork and withstand factors such as heat, moisture, and corrosive residues from cooking processes. This specification helps mitigate the risk of structural failure or fire hazards that can arise from using materials that are too thin.

Materials used in duct construction must not only meet thickness requirements but also be appropriate for the operating conditions they will face. Using the correct thickness, like .054 inches, allows ducts to effectively handle the demands of commercial kitchens, such as increased airflow and temperature variations, while also ensuring compliance with fire safety standards.
