What is the vertical spacing requirement for metal wall ties?

24 inches
36 inches
48 inches
60 inches

The correct answer is: 36 inches

The correct spacing requirement for metal wall ties is 36 inches. This specification aligns with building codes that aim to ensure adequate lateral support for masonry walls. Proper tie spacing is essential for enhancing the structural integrity and ensuring that the wall is stable under various conditions. By having ties placed at this distance, it provides a balance between support and material efficiency, preventing issues like wall movement or failure over time. Understanding the requirement helps builders comply with safety and structural guidelines, contributing to better long-term performance of masonry structures. This knowledge is crucial for contractors to ensure safe building practices and adherence to regulations set forth in the National Building Code and similar standards.
