What type of material is typically required for a shield on concealed venting near framing?

The material typically required for a shield on concealed venting near framing is steel. Steel is chosen for its excellent fire resistance and durability, which are crucial in applications where venting systems must be protected from heat and potential fire hazards. Steel shields can withstand higher temperatures without losing structural integrity, making them suitable for areas that may be exposed to heat sources.

Additionally, steel can provide a sturdy physical barrier that protects the venting system from external damage while ensuring compliance with building codes and safety standards. Its corrosion resistance, especially when galvanized, further enhances its suitability for various environments and applications. Other materials like plastic and aluminum may not provide the same level of heat resistance or structural strength, while wood is not appropriate due to its combustibility in situations where heat is a factor.
