Wood Ramp Construction

Wood ramps can withstand many years of abuse by both skaters and the weather. The critical factors are that wood ramps are designed properly, built by experienced carpenters, and constructed of the right materials. The advantages of wood parks is that they are relatively inexpensive, easy to build and can be placed on an existing concrete or asphalt pad.

Suburban Rails' wood skateparks are built to last, utilizing only the best materials and experienced skatepark builders. Our specifications are some of the most stringent in the industry, and use only rust resistant screws as fasteners (no nail guns or drywall screws).
