What is the gage of the metal tie used on masonry veneer in a residential building?

20 ga
24 ga
22 ga
18 ga

The correct answer is: 22 ga

The correct choice, 22 ga, refers to the gauge of metal ties used in masonry veneer applications in residential buildings. The use of 22-gauge metal ties strikes an optimal balance between strength and corrosion resistance, which is essential in supporting the veneer without adding excessive weight. These ties are designed to hold the veneer securely and provide necessary flexibility during expansion and contraction, which can occur due to temperature changes. In residential construction, adherence to code requirements and best practices is crucial, and 22-gauge metal ties have been recognized for their durability and effectiveness over time. While other thicknesses such as 20, 24, and 18 gauges may also be available or used in different contexts, they do not provide the same combination of structural integrity and lightweight properties that 22-gauge offers specifically for masonry veneers.
