What marterels do you need for a halfpipe?

To build a halfpipe, you'll need several key materials: plywood for the surface, which should be durable and weather-resistant; PVC or metal coping for the edges; and wood or metal framing for the structure's support. Additionally, you'll require screws or bolts for assembly, as well as a non-slip coating for safety. Finally, optional materials like paint or sealant can be used for aesthetics and weather protection.
