What do you mean by “Maintenance-Free” panels?

Maintenance-Free refers to not having to sand, paint, or stain the ThruFlow panels. Though they will not succumb to rot, mildew, or mold, these factors may appear and can be easily removed through regular cleaning or light pressure washing. The pass-through design of our panels will mitigate the build up and exposure to many foreign substances, but things like dirt, sand, ice, snow, spider webs, bird droppings, and other substances should be cleared away as part of a regular cleaning routine.
