12" Poly Balustrade

This architectural railing is the biggest system we offer in any material.  It’s massive size works well on the largest commercial or governmental buildings, and large estates.  And unlike many large cast concrete, cement, or stone balustrades, our polyurethane balustrades are relatively lightweight.  This gives you more options for rooftop balustrade applications, as well as making the installation much easier and more cost effective. For quick planning, expect around $270-$320 per linear foot, depending on your size and design preferences.

D.M. of St. Charles, MO writes on 3/20/25: “Worked with American Porch for designing an exterior stair rail system for a customer. The look and feel of the poly product was excellent. You’d never know it wasn’t wood, which was the highest concern for my client. The office personnel was exceptionally helpful, professional and patient. American Porch will be our go-to from now on!”
