Components of Vinyl Railings

  • Posts

    • As with any railing system, the support pieces are crucial elements in terms of stability. Vinyl rail systems begin with a solid post. Most often a 4x4 treated wood post is used with a vinyl sleeve or "post cladding" that slips over the post to protect it from sun and water damage. This post is then topped with a vinyl post cap available in a variety of styles.

    Rails

    • The top and bottom rails that connect the posts are made from a heavy vinyl that is weather and ultraviolet (UV) ray resistant. To add weight and stability a metal insert, called a "stiffener," is often placed inside the rails. One change in vinyl rail systems is the use of heavy aluminum instead of steel inserts. The aluminum is far more rust resistant and prevents unsightly rust stains as the rails age. Rails are available in a variety of styles and lengths. Often a vinyl support block is placed under the lower rail to give added support to extra long sections or rails that do not include a stiffener.

    Balusters

    • Balusters, sometimes called "pickets," are the pieces that connect the top and bottom rails. Vinyl rail systems are simple to put together because the balusters simply slip into precut holes in the top and bottom rails for assembly. Vinyl balusters are now available from very simple to more ornate styles and unusual contemporary shapes to create a custom look.
