Trex Shenandoah

RAIL FENCE SYSTEM

Why Choose Trex Fencing with the Shenandoah™ Rail Fence System

Shenandoah™ delivers an open, ranch-style look using composite rails and routed posts for fast, clean installs. Choose 2-, 3-, or 4-rail configurations to match your property and sightlines while keeping maintenance to a minimum.

The system’s FDS-patented multi-cell rail insert joins two composite rails into a sturdy 2″×6″ profile with controlled flex. For added rigidity, an optional 1.25″ steel rail tube can be inserted—ideal for livestock pressure and high-traffic perimeters.

Posts are set on efficient centers and the fence follows natural grades for smooth lines. With composite materials, there’s no painting or sealing, and day-to-day upkeep stays easy—perfect for acreage, HOAs, and commercial sites.
