Composite railings offer the look of wood railings with greater durability and little maintenance. Composite railings are made of polyvinyl chloride (PVC) and recycled wood fiber. Composite railing material doesn’t rot, warp, split, or crack like wood. It also never needs sanding, painting, or staining. More homeowners are choosing composite railing over wood for its low-maintenance benefits. The recycled content of composite also make it an environmentally-friendly material option for porch or deck railings
