The PB7513 is a durable polyurethane baluster designed to bring aesthetic harmony to balconies, terraces, and staircases in classical architectural projects. Creating a rhythmic pattern on building facades and interior gallery voids, this decorative balustrade spindle combines the elegance of traditional stonework with the lightweight and high-strength benefits of modern manufacturing technology. Ideal for enhancing both safety and visual appeal, it adds depth and prestige to any facade design.
Technically, this spindle features a 146x146 mm base and a height of 750 mm, perfectly matching standard railing and handrail height regulations. Manufactured from high-density rigid polyurethane (150-220 kg/m³), it offers a surface hardness comparable to wood while remaining lightweight to prevent extra structural load. Thanks to its closed-cell structure, its water absorption rate is below 1%, reducing the risk of rotting, peeling, cracking, molding, or moisture-induced deformation in outdoor conditions for long-lasting durability.
The design highlights a classic turned body with elegant, flowing curves. The balanced circular transitions and cylindrical layers at the top and bottom create an exceptionally aesthetic vertical silhouette. The neck narrows gracefully above a wide circular center, giving the spindle a refined, column-like appearance. When arranged in series, these details establish a balanced, symmetrical rhythm that is easy on the eyes. The smooth surface finish mimics cast marble or hand-carved wood from a distance.
With its versatile application range, this model is a highly preferred polyurethane balustrade element for luxury villa facades, hotel lobby galleries, mansion verandas, staircase railings, and garden walls. Serving as an elegant boundary marker in both classical and neoclassical spaces, it reinforces architectural identity and beautifully separates landscaped areas from building perimeters.
During installation, Polure Polfix polyurethane adhesive must be applied to clean, dry surfaces, followed by mechanical fastening with steel or galvanized screws. The product is shipped with a factory-applied primer that prepares the surface for painting. However, since paint manufacturers do not guarantee adhesion without their own primers, applying an additional primer coat before the final topcoat is optional and left to the customer's preference. Polure does not guarantee paint performance. For outdoor applications, using UV-resistant paint is mandatory.
Compared to plaster, wood, concrete, or marble alternatives, this polyurethane baluster helps prevent cracking, is moisture-resistant, helps deter pests, and is easy to install due to its lightweight nature, providing your projects with a prestigious, low-maintenance, and secure look for many years.
- This baluster model is highly versatile, suitable for both interior and exterior applications
- Outdoors, it serves as an elegant boundary marker on luxury villa balconies, spacious terraces, garden landscape walls, and verandas
- Indoors, it creates a classic atmosphere under staircase handrails in duplex or triplex homes, as well as gallery void railings in hotel and business center lobbies
- By combining this product with handrail profiles in vertical alignments, you can achieve perfect design cohesion in classical and neoclassical architectural projects
- Installation surfaces must be dry, clean, and free of dust
- Apply Polure Polfix polyurethane adhesive to the top and bottom bases of the balusters before positioning them
- In addition to gluing, mechanical fastening with steel or galvanized screws is strictly required for structural safety and stability
- Fill screw holes and joints with a flexible exterior joint filler
- Once dry, sand smooth using 180-220 grit sandpaper
- Following an optional primer coat, complete the process by applying two coats of UV-resistant paint for outdoor use, or water-based/synthetic paint for indoor use
- Assess water and moisture exposure using the product technical data, surface finish and installation details
- It can be easily cleaned with a damp cloth or low-pressure water outdoors
- Avoid using abrasive chemicals and harsh cleaning agents
- For outdoor installations, inspecting the paint and joint fillers once a year, and performing local touch-ups on any hairline cracks, will significantly extend the product's lifespan
Will it be affected by rain and sun when used outdoors?
No, it is perfectly suited for outdoor use. Thanks to its rigid polyurethane structure, its water absorption rate is below 1%, meaning it will not rot or degrade due to rain, snow, or moisture. To protect it from sunlight, it must be painted with a UV-resistant exterior paint after installation.
Is adhesive alone sufficient for installation?
No, adhesive alone is not enough. In addition to applying Polure Polfix adhesive to the top and bottom bases of the balusters, mechanical fastening with steel or galvanized screws is strictly mandatory to ensure structural safety and stability.
Can the product be painted directly, or is an extra primer required?
Our product is shipped with a factory-applied primer coat, making the surface ready for paint. However, since paint brands do not guarantee adhesion on surfaces where their own primers are not used, applying an additional primer before the topcoat is optional and depends on the customer's preference.
What are its advantages compared to plaster or concrete balusters?
Include the product weight and fixing loads when assessing the substrate and supporting structure. It is also highly impact-resistant, so it won't crack, crumble, or chip over time. Being moisture-resistant, it helps reduce the likelihood of mold or pests.
Are the dimensions of the product suitable for standard railing projects?
The PB7513 model features a 14.6 cm wide square base and a height of 75 cm. This height is designed to perfectly comply with standard balcony and staircase railing height regulations and ergonomics when combined with the handrail profile to be added on top.
