For almost 40 years Pacific Outdoor Products has been manufacturing timber playgrounds out of a select grade of Hemlock or Douglas Fir that is extremely well suited for the manufacture of outdoor playground equipment. Timber Playsystems wood play structures are an attractive and natural fit in any play area. The 6×6 custom cut timbers are inspected, hand drilled, routed, sanded and pressure treated with an approved ACQ wood preservative. All the edges on the vertical support posts are rounded, the tops have a 45-degree edge for safety and they are pre-drilled for easy installation. EPA approved pressure treating is applied after fabrication is complete and protects the wood from decay, fungus and termites. These heavy duty timber playgrounds blend into the landscape for a natural look and feel and the modular design means customization is a breeze.
