What is the minimum gauge steel required for hoods in fire safety?

The minimum gauge steel required for hoods in fire safety is 18 gauge. This specification is important because the steel used in the construction of hoods must be capable of withstanding high temperatures and potential fire conditions without failing. Using 18 gauge steel ensures a balance between durability and weight, providing adequate protection while preventing structural collapse or deformation when exposed to heat from cooking equipment or fire.

In fire safety applications, particularly concerning kitchen exhaust hoods and similar installations, manufacturers and codes often set guidelines around the materials used to ensure they have the necessary fire resistance and structural integrity. Steel with a gauge lower than 18 (meaning thicker and stronger) would also be acceptable, but 18 gauge is the minimum standard that offers sufficient strength and resistive properties. Hence, this requirement serves to enhance overall fire safety and compliance with regulations in commercial kitchens and other environments where fire hazards are prevalent.
