The PB7516 model is a decorative baluster post featuring classic architectural details, specially designed for balcony, terrace, and staircase railing systems. Suitable for both interior and exterior applications, this element offers a highly durable and practical alternative to heavy cast concrete or rot-prone wooden balusters. Adding value to your architectural projects, it combines aesthetic elegance with structural safety to beautifully define the boundaries of your spaces.
The product measures 168 mm in width, 168 mm in depth, and 750 mm in height. Manufactured from high-tech rigid polyurethane, this model features a density of 150-220 kg/m³, offering a wood-like hardness while remaining lightweight to prevent unnecessary structural load. Thanks to its closed-cell structure, its water absorption rate is below 1%, protecting it from harsh outdoor conditions such as rain, snow, and frost. Designed to maintain its shape over time, it helps prevent warping, expansion, or cracking.
Visually, the design seamlessly blends the smooth contours of traditional woodturning craftsmanship with modern manufacturing quality. Its symmetrical, elegantly curved body, combined with circular collars and geometric bases at the top and bottom, integrates flawlessly into classic and neoclassical architectural projects. The smooth surface finish enhances the quality of the final paint coat, while the fluid form of the post creates an elegant, visually pleasing rhythm along vertical lines.
Offering a wide range of applications, this baluster is highly favored for exterior balconies in villas and residential projects, French balconies, and spacious terraces or verandas. Indoors, it serves as a prestigious decorative element for duplex staircases, hotel lobby atriums, and partition railings in restaurants. For outdoor installations, coating the product with a UV-resistant paint post-assembly is mandatory to protect it from the degrading effects of sunlight.
Installation should be planned on a clean, dry surface. For bonding, Polure Polfix polyurethane adhesive must be used to ensure a strong grip; flexible silicone-based adhesives are not suitable. For safety reasons, the balusters must be mechanically secured with screws at both the top and bottom mounting points. Once screw heads and joints are filled with an exterior-grade filler and sanded smooth, the painting process can begin. The product is shipped with a factory-applied primer; however, an additional coat of primer is optional, depending on customer preference or the paint manufacturer's warranty terms.
- This polyurethane baluster model is designed for use in both indoor staircase railings and outdoor balcony or terrace balustrades
- It provides an elegant look for defining spacious terraces, pool-side safety barriers, French balcony supports, and villa entrance stairs
- Indoors, it functions as a stylish vertical support element in atrium railings for hotels, restaurants, or residential projects
- It can be combined with compatible handrail profiles to create seamless and secure railing lines
- The installation surface must be clean and dry
- The top and bottom bases of the balusters are bonded to the mounting surface using Polure Polfix polyurethane adhesive
- In addition to the adhesive, mechanical fastening using screws or anchors through the products is mandatory for safety
- Screw holes and joints are filled with exterior-grade filler, and once dry, sanded smooth with 180-220 grit sandpaper
- An optional primer coat can then be applied, and the process is completed with at least two coats of exterior-grade paint
- Polyurethane balusters maintain their pristine appearance for many years with minimal maintenance
- Indoors, they can be cleaned by dusting or wiping with a damp cloth
- For outdoor installations, the painted surface should be inspected once a year, and touch-ups applied if necessary
- While they can be pressure washed, harsh abrasive chemicals and wire brushes should be avoided during cleaning to prevent damaging the paint coat
Can the PB7516 polyurethane baluster be used outdoors?
Yes, because this product is made of closed-cell polyurethane, it is highly resistant to water, moisture, and frost. It can be safely used outdoors; however, to protect it from UV rays, it must be coated with a UV-resistant exterior paint after installation.
Which adhesive should I use for installation?
For installation, Polure Polfix polyurethane adhesive, which offers high strength and fast curing, should be used. Silicone or similar flexible sealants are not suitable for structural fastening and may fail over time.
Is the product shipped pre-painted?
Our product is shipped with a factory-applied white primer. This primer helps the final coat of paint adhere better to the surface. However, applying an additional primer coat is optional and depends on the paint brand and your application preferences. Polure does not warrant the paints used.
What are the advantages compared to concrete balusters?
Polyurethane balusters are extremely lightweight compared to their concrete counterparts, adding no static load to the building, and are much easier to install. Additionally, unlike concrete, they do not crack or crumble over time, preserving their smooth surface details for many years.
What is the impact and break resistance of the product?
The rigid polyurethane body, produced with a density of 150-220 kg/m³, offers a hardness similar to wood. This provides high mechanical resistance against impacts. It does not break or dent easily like plaster or EPS foam products.
