Polymer Stone Balustrade Systems
Architectural Mall manufactures Polymer Stone balustrade and exterior railing systems for balconies, porches, stairways, terraces, rooftops, and architectural projects where a stone appearance, structural performance, and long-term durability are important.
Polymer Stone is a synthetic stone material made from calcium carbonate, polyester resin, UV-inhibited color pigment, and proprietary additives. Unlike paint-grade systems, Polymer Stone is factory-finished with color integrated into the material, so it does not require on-site painting before installation.
Depending on the selected color and texture, Polymer Stone can resemble painted wood, limestone, sandstone, or other architectural stone-like finishes. Compared with natural limestone, cast stone, or concrete, Polymer Stone offers a similar architectural appearance with reduced weight and easier handling.
What Are Polymer Stone Balustrades?
Polymer Stone balustrade systems are made up of rails, balusters, newel posts, post caps, finials, and related hardware, all manufactured from the same synthetic stone material for a consistent appearance throughout the assembly.
Architectural Mall manufactures these systems in a wide range of sizes, styles, colors, textures, and configurations. Components can be selected or customized to meet the project’s required height, span, layout, and architectural style, including residential, commercial, and historic restoration applications.
Structural Performance, Long Spans & Curved Layouts
Polymer Stone balustrades are designed for structural exterior railing applications on residential and commercial projects. The material provides a stone-like appearance while reducing weight compared with natural limestone, cast stone, concrete, or solid masonry alternatives.
Select Polymer Stone rail systems can span up to 20 feet before requiring a newel post, column, or other support, depending on the rail profile, system style, and project requirements. This makes Polymer Stone a strong option for larger balconies, terraces, porches, and architectural railing layouts where longer uninterrupted rail runs are preferred.
Polymer Stone is also the preferred material for curved balconies, radius layouts, and curved stair applications. Unlike HDP polyurethane, which is best suited for straight railing runs and straight stairs, Polymer Stone can be manufactured for both straight and curved balustrade designs.
Polymer Stone Colors, Textures, and Finish Options
Polymer Stone balustrades are factory-finished with color integrated into the material, rather than relying on a jobsite paint finish. Standard textured color options include White, Off-White, Cream, Sandstone, Limestone, Cliffside Grey, and Royal Coral.
Smooth finishes may also be available for these colors, and custom colors may be available for an additional charge. Because screen colors and production batches can vary, physical color samples are recommended before making a final selection.
Polymer Stone Balustrade Systems, Sizes & Custom Options
Polymer Stone balustrade systems are available in several rail sizes and can be configured with compatible balusters, posts, caps, and layout options. Select a system below to compare scale and component details. Click any balustrade system image to view an installed project example.
4″ Balustrade System
The 4″ Polymer Stone balustrade system is a lighter-profile option for projects that do not need the larger scale of wider rail assemblies but still require a synthetic stone balustrade system. Additional baluster styles are available beyond the Crowne Terrace style shown here.
6-3/4″ Balustrade System
This system is slightly smaller than our 7-1/2″ option. The system is pictured with our 7″ Post but would work well with the 9″ Post. Some customers use our 7-1/2″ system with the 12″ Newel Post, depending on personal preference or project objective. We have many baluster styles to choose from that work with this railing system.
7-1/2″ Balustrade System
The 7-1/2″ Polymer Stone balustrade system is one of the most commonly selected options for residential and builder projects. It offers a balanced architectural scale and can be configured with compatible baluster styles, including taller balusters for projects requiring a 42″ overall system height.
10″ Balustrade System
The 10″ Polymer Stone balustrade system is the largest standard rail option and is suited for projects that call for a stronger architectural scale. Port Yelena is designed exclusively for the 10″ rail system, while many balusters from the 7-1/2″ system may also be compatible depending on the desired configuration.
Polymer Stone vs Polyurethane Balustrades
Polymer Stone and HDP polyurethane balustrades are both exterior architectural railing systems, but they serve different project needs.
Polymer Stone is usually the better choice for factory-finished color, stone-like textures, longer rail spans, curved or radius layouts, and projects where a synthetic stone appearance is preferred. HDP polyurethane is usually the better choice for lightweight, paint-grade, straight railing runs and straight stair applications.
For projects where both appearance and weight matter, the two materials may also be used together. HDP polyurethane may be selected for upper balconies or rooftop areas, while Polymer Stone may be selected for areas where a factory-finished stone-like material is preferred.
