What is the horizontal spacing requirement for metal wall ties?

1. 12 inches

2. 24 inches

3. 36 inches

4. 48 inches

The correct answer is: 36 inches

The correct answer reflects the established standard in construction practices for the spacing of metal wall ties. In masonry construction, specifically when dealing with brick or stone veneer, wall ties are critical components that help anchor the veneer to the structural support behind it, ensuring stability and minimizing movement. Metal wall ties are typically required to be spaced at intervals of 36 inches horizontally. This spacing helps distribute loads effectively across the wall and provides adequate support to prevent any potential issues, such as bowing or cracking, that may arise from inadequate support. Proper installation and spacing of these ties are essential to maintain the structural integrity and longevity of masonry walls. Understanding these spacing requirements is crucial for compliance with building codes and for the successful performance of wall systems. This knowledge is particularly important for professionals in construction and contracting, as adherence to these standards significantly impacts both safety and structural performance.
