The PBK28 is a professional-grade architectural handrail profile engineered to provide a durable, refined capping solution for balustrade systems, terraces, and staircases. Manufactured from high-density rigid polyurethane, this profile offers the structural presence and touch of premium timber without any of the natural vulnerabilities. It serves as an excellent finishing cap for both residential and commercial properties looking to achieve a classic architectural aesthetic.
With dimensions of 278 mm in width, 2400 mm in length, and 50 mm in thickness, this profile features a dense composition of 150-220 kg/m³ (production target ~160 kg/m³). Its closed-cell structure ensures a water absorption rate of less than 1%, making it completely impervious to moisture, rot, and insect infestation. Designed to withstand extreme environmental conditions, it maintains absolute dimensional stability within a temperature range of -100 °C / +80 °C, resisting warping, shrinking, or cracking over time.
Aesthetically, the PBK28 presents a smooth, flat top surface paired with elegant stepped profiles along the outer edges, facilitating a comfortable grip and a clean shadow line. The underside of the profile is engineered with integrated structural channels designed to seamlessly fit over standard baluster tops or metal sub-frames, simplifying alignment during installation and ensuring a secure, flush fit.
This high-density capping profile is ideal for finishing balcony railings, veranda boundaries, terrace borders, and grand indoor or outdoor staircases. Its lightweight nature significantly reduces structural loads on cantilevered balconies and simplifies logistics on-site, making it a preferred choice for architects and contractors working on premium European restoration and new-build projects.
Installation is straightforward and efficient. The profile is mounted using high-quality polyurethane (PU) assembly adhesive combined with mandatory mechanical screw fastening for structural safety. The product arrives with a factory-applied primer coat that prepares the surface for painting. Please note that while this primer provides an excellent base, the application of an additional primer prior to the final topcoat is optional and depends on the specific guidelines of your chosen paint manufacturer.
- This wide architectural handrail profile is specifically engineered for capping balustrade systems, balcony edges, and structural railings
- In outdoor residential projects, such as classical villas, coastal estates, or commercial hotel terraces, it serves as a weather-resistant cap over baluster columns
- Indoors, it is highly suitable for grand staircases in luxury hotel lobbies, private residences, or corporate offices
- Its substantial 278 mm width is ideal for concealing underlying concrete, stone, or steel reinforcement rails, providing a smooth and comfortable surface to touch
- For all outdoor applications, finishing the profile with a UV-resistant paint is mandatory to prevent discoloration from sunlight exposure
- Ensure the mounting surface is clean, dry, and free of dust
- Cut the PBK28 profile to the required lengths using standard woodworking miter saws
- Apply a continuous bead of high-quality polyurethane (PU) assembly adhesive along the contact surfaces
- Secure the profile mechanically using stainless steel screws to guarantee structural stability
- Fill all joints and screw heads with an exterior-grade acrylic filler, and sand smooth with 180-220 grit sandpaper once dry
- The product comes pre-primed from the factory; however, the use of an additional primer before applying the final two coats of paint is optional and should align with your paint supplier's warranty requirements
- Use premium UV-resistant paint for all exterior installations
- The closed-cell polyurethane structure requires minimal maintenance compared to traditional timber or concrete
- It does not rot, swell, or host mold
- For routine maintenance, wipe the surface with a damp cloth and mild detergent
- High-pressure water washing is safe for outdoor installations, but abrasive chemicals or solvents must be avoided
- We recommend inspecting the paint finish annually in high-exposure outdoor areas and reapplying a UV-resistant topcoat if weathering is visible
