Which is a requirement for veneer ties?

The requirement for veneer ties to be made of No. 9 gauge for strand wire is based on industry standards for structural integrity and durability. No. 9 gauge wire strikes a balance between strength and flexibility, which is essential for supporting brick or stone veneer in construction. This gauge is thick enough to withstand loads and environmental stressors while being flexible enough to allow for the necessary movement due to temperature changes and settling of the building.

Using a wire of appropriate gauge ensures that the ties can effectively anchor the veneer to the structural framework, preventing issues such as cracking or detachment over time. Adhering to these standards is critical for the longevity and safety of the construction, and it's standard practice in the residential building industry to ensure proper installation of veneer materials.
