What is the minimum metallic coating requirement for load-bearing, cold-formed steel framing?

• A. G 40
• B. G 60
• C. G 80
• D. G 100

Answer: (B)

The minimum metallic coating requirement for load-bearing, cold-formed steel framing is G 60. This designation indicates a zinc coating of at least 0.60 ounces per square foot, which balances corrosion resistance with the structural needs of load-bearing applications. Cold-formed steel is often used in various structural and architectural applications, and G 60 ensures adequate protection against corrosion, particularly when exposure to moisture is anticipated. Stronger coatings, such as G 80 or G 100, provide even better corrosion resistance but may not be necessary for all projects and can increase costs. Similarly, G 40 provides less protection and would not be suitable for load-bearing structures, hence why G 60 is the accepted standard in this context. Understanding these specifications is crucial for ensuring both the safety and longevity of steel framing in construction projects.
