Porch Post, Poly


A load bearing polyurethane porch post provides the traditional look and feel of wood, but will not rot, warp, or crack. Includes install hardware and 2 trim collars.



A Polyurethane Porch Post is the taller support post that holds up a roof extension over a porch.  If you’re looking for Newel Posts, which are shorter and hold only the railing, click Wood Newel Posts or Synthetic Newel Posts.  A polyurethane porch post is a synthetic alternative to the traditional lathe-turned wood post. They look and feel much like wood, with crisp, clean lines and a warm feel.  These posts are reinforced with an internal 2 7/8″ dia. steel pipe that provides a 2000 lb load bearing strength.  They are factory primed and ready for installation and paint.  Very low maintenance.

Installation hardware is included with each Porch Post.  Two trim collars are also included for a finished look at the top and bottom.

Polyurethane Product Material

Our “poly” products are made from environmentally friendly water-based High Density Polyurethane (also called urethane, HDP, or simply Poly).  The material is similar in density to a softwood such as white pine.  Unlike PVC or Vinyl, our Poly material looks and feels like authentic wood.  Each pattern is made to exacting dimensions by our staff of Master Patternmakers.  The edges of American Porch polyurethane balustrade products are sharp, clean, and offer the true authentic look and feel of wood.  It comes factory primed with a high emulsion latex paint that can be finish coated with any high quality exterior latex paint.

Polyurethane spindles are reinforced with an internal PVC pipe for strength and rigidity.  The rails are reinforced with either a PVC or Aluminum pipe.  Cut our Poly spindles and PVC-reinforced rails using normal woodworking techniques.  For rails with an internal aluminum pipe, a slow speed cutoff saw, a.k.a. multi-cutter, works best.

While many of our customers prefer the authenticity of wood, there is no question that urethane products have a few advantages.  Urethane is very low maintenance. The paint is chemically bonded during the molding process which prevents cracking and peeling. An additional primer is applied before shipping all orders. Urethane will not take on moisture, which allows it to withstand the environmental elements. It will not rot and is impervious to insects. Urethane simulates wood, is structurally sound and is the perfect enhancement for any of your building or remodeling projects.

American Porch polyurethane balustrade products are made here in the USA.
