Class I materials are suitable for structures not exceeding what height?

Class I materials are commonly associated with structures that are not intended to be highly susceptible to lightning strikes and are designated for use in buildings with specific height limitations. In this case, the designation of Class I materials is appropriate for structures that do not exceed 75 feet in height or approximately 22.86 meters.

This height limitation is significant because it helps to mitigate the risk of lightning damage. Structures above this height may be more prone to lightning strikes due to their prominence in the landscape, which is why different classes of materials and protection systems are established based on height and other factors. Class II and Class III materials would be relevant for taller edifices, as they involve higher levels of protection and different compliance standards.

By understanding this limitation regarding Class I materials, one can effectively apply lightning protection strategies that are in alignment with the safety standards necessary for the intended structure height.
