Technical Specifications and Structural Performance of Handrails and Balusters Systems
High-density rigid polyurethane (PU) serves as the primary material for the engineered Handrails and Balusters System systems, offering a highly durable alternative for premium architectural projects. Manufactured with a closed-cell structure, these architectural elements possess a density of 150-220 kg/m³ (production target ~160 kg/m³), providing a structural hardness comparable to natural wood while remaining significantly lighter. This density range ensures high impact resistance and secure screw retention during installation without adding unnecessary dead load to balconies, terraces, or staircases.
Thermal stability is a key performance factor for these structural elements. The material tolerates temperatures from -100 °C / +80 °C without experiencing warping, shrinkage, or dimensional deformation. Due to its closed-cell chemical configuration, water absorption remains under 1%, making the system completely resistant to rot, mildew, and moisture-induced swelling. In terms of fire safety, the material exhibits self-extinguishing behavior, meaning it ceases to burn once the external flame source is removed.
Architectural Geometry and Model Profiles
The Handrails and Balusters System product line includes diverse structural profiles engineered to meet various load-bearing and design requirements. Standard vertical balusters, such as the PB4014 and PB7516 models, provide reliable proportions for typical balcony heights, while the elongated PB9013 model is suited for high-ceilinged galleries and grand staircases. These balusters are paired with matching handrail profiles, including the linear PBK20 profile for minimalist setups and the wide, multi-tiered PBK28 profile for classical architecture.
For curved layouts, such as spiral staircases or semi-circular balconies, specialized radius profiles like 2PBK20D528H and PBK28D304H allow seamless integration. Every component is molded with high-pressure CNC-machined tools, ensuring crisp detailing, uniform dimensions, and a smooth surface finish that eliminates the structural inconsistencies, knots, or voids commonly found in timber or cast stone alternatives.
Surface Finishing and Paint Compatibility
All Handrails and Balusters System components are shipped with a factory-applied primer that prepares the surface for final coating. This factory primer is compatible with high-quality water-based and synthetic paints. However, paint manufacturers typically do not guarantee paint adhesion on surfaces where their own proprietary primers have not been applied. Consequently, the application of an additional primer layer prior to final painting is optional and remains the sole responsibility of the customer. Polure does not provide any warranty for the paints applied to its products and accepts no liability for paint performance.
For all outdoor installations, the application of a high-quality UV-resistant paint is mandatory. Unpainted polyurethane materials are susceptible to yellowing when exposed to direct solar radiation. The final paint layer serves as a protective barrier against environmental degradation, ensuring long-term color stability and surface integrity.
Usage Areas
The Handrails and Balusters System systems are designed for both structural interior design and demanding exterior facades. In interior spaces, they are utilized for grand staircases in duplex residences, luxury hotels, and commercial mezzanine levels to secure gallery openings. For exterior applications, these balustrade systems are installed on residential balconies, classical terraces, French window barriers, and outdoor pool enclosures. The low weight of the 150-220 kg/m³ (production target ~160 kg/m³) material makes it particularly suitable for historical renovation projects where historic facades must be preserved without adding heavy structural loads to older masonry.
Installation
Successful installation of Handrails and Balusters System systems requires systematic execution. First, ensure the mounting surface is clean, dry, and structurally level. Mark the placement of each baluster, maintaining a standard interval of 10 to 15 cm. Cut the handrail profiles using a miter saw at precise 45-degree angles for corner joints. For bonding, apply polyurethane (PU) mounting adhesive generously to all contact joints; do not use silicone adhesives. Mechanical fastening using screws is mandatory to anchor the balusters and handrails securely to the substrate. After securing the hardware, fill all screw holes and joint seams with an exterior-grade joint filler. Sand the filled areas using 180-220 grit sandpaper to achieve a flush surface. Finally, apply an optional secondary primer if required by your paint manufacturer, followed by two coats of premium UV-resistant paint.
Care Information
The high-density polyurethane structure of the Handrails and Balusters System system requires minimal maintenance. Periodic cleaning should be performed using a damp microfiber cloth and mild, non-abrasive detergents. Avoid using harsh chemical solvents, high-pressure washers, or abrasive brushes, as these can degrade the protective paint layer. For outdoor installations, inspect the joints and filler points annually to ensure structural integrity against seasonal shifts.
