Fence rails

Fence rails are horizontal timber pieces used to join fence posts and support vertical boards or panels. In modern construction, they give structural integrity to fences on residential, commercial, and agricultural sites. You’ll commonly use them for perimeter fencing, partitioning spaces, or as part of acoustic or security barriers. While they’ve traditionally been hand-sawn, today most rails are pressure-treated and machine-cut to consistent dimensions.

You’ll find a variety of fence rail types suited to different structural needs and site conditions. Options include arris rails for closeboard fencing, cant rails for featheredge systems, and square or rectangular rails for general use. Most are available in softwood and treated for durability, though untreated rails are also used for temporary work. Some come notched or pre-shaped to work with morticed posts, while others are square-edged for flexible fixing. Choose rail lengths and profiles based on span, load, and desired finish.
