What type of materials can be used as scaffold planking?

The use of wooden or composite materials for scaffold planking is prevalent due to their strength, durability, and ability to support heavy loads while providing a safe working surface. Wooden scaffolding planks are commonly made from high-quality timber that is specifically treated to resist warping and moisture, ensuring stability and safety. Composite materials often combine wood fibers with synthetic resins, creating a robust product that can withstand the elements better than pure wood, while also being lighter and providing good slip resistance.

Metal planking, although not the chosen answer, is also valid; however, options that focus on wooden and composite materials highlight their traditional use and regulatory acceptance in various safety standards. Plastic materials are generally not suitable for scaffolding plank usage due to their lower strength and potential for deformation under heavy loads. Therefore, the best answer focuses on wooden and composite materials, which are widely recognized and utilized in scaffold construction.
