What is the minimum thickness required for sheet steel used in ductwork for dryer exhaust?

The minimum thickness required for sheet steel used in ductwork for dryer exhaust is 0.0187 inch. This specification is important because it ensures that the ductwork can withstand the high temperatures and pressures associated with dryer exhaust while also providing adequate durability to handle moisture and minimize the risk of corrosion.

By adhering to this minimum thickness, the ductwork is less likely to deform or develop leaks, which could potentially lead to fire hazards or inefficiencies in dryer operation. Using materials that meet or exceed this requirement also contributes to compliance with building codes and standards, enhancing safety and performance.

Selecting a thickness greater or less than the specified value can lead to either excessive material use and costs or insufficient durability and safety, underscoring the importance of following established guidelines in duct construction for dryer exhaust systems.
