What is the minimum thickness for stainless steel used in exhaust fan housings?

The minimum thickness for stainless steel used in exhaust fan housings under the NFPA 96 standard is established to ensure durability and effectiveness in handling high-temperature and potentially corrosive environments typical of commercial cooking operations. The correct specification indicates that a thickness of .043 inches offers sufficient strength and resistance to deformation, which is critical for maintaining structural integrity, longevity, and safety in the exhaust systems.

Using the correct thickness helps ensure that the fan housings are robust enough to withstand regular wear and tear as well as the harsh conditions they encounter, such as high heat and grease-laden air. This measurement aligns with industry standards and safety regulations intended to reduce fire hazards associated with commercial cooking activities.
