The PBK20 handrail profile is a durable architectural component designed as a top cap for both interior staircases and exterior balustrade systems. Engineered as a modern polymer alternative to traditional wood or heavy concrete, this lightweight solution delivers classic architectural lines with only a limited load on the structure. Its rot-resistant and crack-proof composition ensures long-lasting performance.
The product is manufactured with a length of 240 cm, a width of 20 cm, and a height of 5 cm. Featuring a high-density rigid structure of 150-220 kg/m³ (production target ~160 kg/m³), it offers surface resistance comparable to hardwood. Assess water and moisture exposure using the product technical data, surface finish and installation details. It retains its shape flawlessly under temperature fluctuations ranging from -100 °C / +80 °C.
Visually, the design features a flat, smooth top surface for a comfortable grip, complemented by elegant stepped bevel details along the edges. The specialized recessed channel on the underside allows balusters (spindles) to fit perfectly, ensuring seamless alignment and enhanced structural integrity during installation.
Highly versatile, this profile is widely preferred for residential balconies, hotel atriums, spacious terrace borders, and indoor stair handrails. For outdoor applications, applying a UV-resistant topcoat is mandatory to protect the material from yellowing under direct sunlight.
During installation, the profile should be miter-cut at a 45-degree angle and placed on a clean surface. For bonding, only Polure Polfix adhesive must be used; silicone-based products should be avoided. Mechanical fastening with screws is required. While the product comes factory-primed, applying an additional primer coat is optional, depending on the warranty terms of your chosen paint brand.
- The PBK20 handrail profile is a highly versatile element that serves as both a boundary and a support in interior and exterior architecture
- It is reliably used on villa balconies, French balcony projects, and as the top rail for open terrace balustrades
- Indoors, it provides an elegant, tactile grip for grand staircases in hotel lobbies, restaurants, and multi-story residences
- When paired with baluster columns, it creates a cohesive, integrated look for landings and atrium railings
- For exterior installations, it must be coated with UV-resistant paint to ensure long-term weather protection
- The installation surface must be clean and dry
- Prepare the joints by miter-cutting the profile ends at a 45-degree angle
- Apply Polure Polfix adhesive to the mounting surface and joints; do not use silicone
- Mechanically secure the product to the surface using screws
- Fill screw heads and joints with exterior-grade filler, and once dry, sand the surface smooth using 180-220 grit sandpaper
- An additional primer coat can be optionally applied based on the paint manufacturer's recommendation, followed by two coats of paint to complete the process
- The surface can be easily cleaned with a damp cloth; avoid using harsh, abrasive chemical cleaners
- For outdoor installations, we recommend periodically checking the paint condition and refreshing it with UV-protective paint if necessary
- Any minor impact damage can be easily repaired using filler and touch-up paint
Can the PBK20 handrail profile be used outdoors?
Assess water and moisture exposure using the product technical data, surface finish and installation details. It can be safely used outdoors; however, to prevent yellowing from sun exposure, it must be coated with a UV-resistant topcoat after installation.
Which adhesive should be used for installation?
To ensure strong adhesion and a proper seal during installation, only Polure Polfix adhesive should be used. Silicone-based adhesives are not suitable as they do not provide the required structural strength.
What are the advantages compared to plaster or wooden handrails?
It is exceptionally lightweight and shatterproof compared to plaster. Unlike wood, it does not rot, crack, warp, or attract insects over time due to moisture. Include the product weight and fixing loads when assessing the substrate and supporting structure.
Is it necessary to apply an additional primer before painting?
The product is shipped factory-primed and ready for painting. However, since some paint manufacturers do not warranty applications done without their own primers, applying an additional primer coat post-installation is entirely optional and left to the customer's preference.
What is the purpose of the channel on the underside of the profile?
The recessed channel on the bottom of the profile is designed to allow the tops of the balusters (spindles) to fit perfectly inside. This not only simplifies installation but also establishes a strong mechanical bond between the balustrade system and the handrail.
