What type of load does decking primarily support in construction?

Decking primarily supports static loads in construction. Static loads refer to loads that are applied slowly and remain relatively constant over time, such as the weight of the decking material itself, any attached fixtures, or permanent structural components. In a construction context, decking serves as a platform for workers and equipment, facilitating tasks without significant movement or dynamic forces acting upon it.

The characteristics of static loads mean that decking is designed to handle these stable weights without the need for adjustment during usage. This contrasts with dynamic loads, which involve forces that change over time, such as those caused by moving vehicles or machinery. While decking may experience some live loads temporarily—such as the weight of workers or equipment—its primary role is to support static loads associated with the building structure and elements that remain in place for extended periods.
