Aluminum, galvanized steel, and stainless steel safe pans shall be of at least what gauge material?

  1. 18

  2. 20

  3. 22

  4. 24

The correct answer is: 24

The correct answer, which specifies that aluminum, galvanized steel, and stainless steel safe pans shall be of at least 24 gauge material, aligns with the regulations to ensure durability and safety in plumbing systems. In the context of plumbing practices, using a suitable gauge is crucial for maintaining structural integrity, preventing corrosion, and ensuring long-term functionality. Higher gauge numbers correspond to thinner materials, which can compromise the safety and effectiveness of a plumbing system. By requiring a minimum of 24 gauge, the code helps ensure that the pans can withstand environmental stresses, resist damage, and provide reliable performance in accordance with safety standards in plumbing installations.
