What is the minimum gauge of sheet metal veneer wall ties?

• A. 22 gauge
• B. 18 gauge
• C. 16 gauge
• D. 20 gauge

Answer: (A)

Sheet metal veneer wall ties must be thick enough to resist bending and pullout under loads, yet not so thick that they waste material or hinder installation. The minimum thickness specified for these ties is 22 gauge. This thickness provides adequate strength when the tie is embedded in mortar and connected to the backing, while keeping costs reasonable. Using thinner material would risk deformation or failure under wind or movement, and thicker gauges (18, 16, or 20) would work but aren’t required for the minimum standard and would add unnecessary expense. So 22 gauge is the smallest acceptable thickness that meets typical performance needs.
