Final answer:
The minimum nominal thickness of glazing used in handrail assemblies or guard sections is often ¼ inch, but local building codes and standards should be consulted for exact specifications.
Step-by-step explanation:
The question relates to the specifications for materials used in construction, more specifically in a handrail or guard section of a building structure. The minimum nominal thickness of glazing used in this context is typically dictated by building codes and standards, which can vary depending on the region and the specific application of the glazing. In many cases, the minimum nominal thickness of glass in a handrail or guard assembly is ¼ inch (6 mm) to ensure safety and durability. However, local building codes may have different requirements, and it is essential to consult the relevant building codes and standards for exact specifications.
