What is the maximum horizontal spacing between ties in the U.S.?

The maximum horizontal spacing between ties in the U.S. is dictated by safety regulations and design standards that ensure the structural integrity and stability of scaffolding. By selecting the maximum spacing of 30 feet, it reflects best practices that maintain the support needed for the scaffolding system while allowing for sufficient access and safety for workers and materials being handled. This spacing helps in stabilizing the scaffold against lateral forces and minimizes the risk of collapse, ensuring that the structure can safely support the required loads.

Other spacing options, such as 10 feet, 15 feet, and 20 feet, may be more conservative and could be applicable in specific contexts or local regulations, but they do not represent the maximum allowable distance. Instead, the chosen maximum spacing of 30 feet strikes a balance between practicality and compliance with safety standards, allowing for efficient scaffold construction without compromising on safety.
