Balustrade System 5 1/2"

The 5-1/2″ Polyurethane Balustrade System is a great balustrade system to add style and elegance to any home or commercial project. It is a more economical line due to the smaller design in the railings and individual balustrades. This polyurethane balustrade system is ideal for smaller balconies and areas that desire less space taken up by the actual balustrade system. This balustrade system railing has a PVC core on the inside of the polyurethane covered top and bottom rail to give it strength and rigidity This strength allows this railing to pass BOCA and ICC building codes. There are many balustrade options available in this polyurethane balustrade system and custom turnings are available. The 5-1/2″ Balustrade system can be custom curved to any radius for stairs or flat balconies.
