The P5840D decorative architectural element is a helical column shaft designed for those wishing to bring the elegance of classical and neoclassical architecture into their living spaces. With a generous 40 cm diameter and a height of 240 cm, it perfectly fits standard ceiling heights, offering a non-structural, aesthetic column cladding solution for both interior and exterior projects. The spiral fluting shown in the image refracts light from various angles, creating a sense of depth and setting it apart from ordinary flat column designs.
Manufactured from high-density (150-220 kg/m³) rigid polyurethane (PU), this product offers a surface hardness comparable to wood while remaining lightweight, ensuring it adds no static load to the building structure. Its closed-cell structure keeps water absorption below 1%, preventing moisture, rot, decay, or swelling. With dimensional stability tested between -20 °C and +70 °C, this column maintains its dimensional stability for years without warping or expanding.
The smooth spiral contours of the P5840D model are flawlessly shaped using advanced production technologies. This elegant twisted shaft serves as a striking focal point for spacious living rooms, prestigious hotel lobbies, or grand restaurant entrances. The surface comes pre-primed with a factory white primer, optimized for excellent paint adhesion. However, due to the specific warranties offered by paint manufacturers for their own priming systems, applying an additional primer coat before or after installation is entirely at the user's discretion. Polure does not warrant the paints used.
Featuring a versatile design, this hollow column can easily wrap around unsightly concrete pillars, utility pipes, or steel supports. It can be paired with matching capitals and bases to elevate villa entrances, building facades, wedding venues, or garden landscapes. For outdoor applications, it must be coated with UV-resistant exterior paint to prevent yellowing or discoloration from sun exposure.
Unlike fragile plaster or heavy concrete alternatives, this durable product carries a low risk of breakage and is exceptionally easy to transport and install. To install, apply Polure Polfix adhesive to a clean, dry surface, position the column, and secure it mechanically with screws at the top and bottom. Once screw holes and joints are filled with putty, sand the surface with 180-220 grit sandpaper and finish with two coats of paint.
- Polyurethane columns are highly favored in both interior design and exterior architecture due to their versatile applications
- Indoors, they can be used to divide spacious living rooms, frame hallways and corridor transitions, or serve as decorative accents around fireplaces
- In prestigious venues such as hotel receptions, luxury restaurants, wedding halls, and convention centers, they add depth and a classical character to the space
- The hollow structure of these columns makes them an excellent cladding option to aesthetically conceal existing concrete pillars or steel support beams
- Outdoors, they are ideal for creating grand entryways on either side of villa entrance doors, supporting open verandas and terraces, or designing majestic gazebos in garden landscapes
- When combined with matching capital and base models, they bring vertical dynamism and a rich architectural identity to any facade
- For the installation of polyurethane spiral columns, first ensure that the application surface is dry, clean, and free of dust
- Only Polure Polfix adhesive, which offers high bonding strength, should be used for installation; silicone-based adhesives must be strictly avoided
- After applying the adhesive, mechanical securing with screws at the top and bottom points is mandatory for safety
- Screw heads and joints should be filled with an exterior-grade putty, and once dry, sanded smooth with 180-220 grit sandpaper
- In the final step, an optional extra coat of primer can be applied over the factory primer, followed by at least two coats of water-based or synthetic paint
- Maintaining polyurethane columns is highly practical
- For indoor applications, they can be easily cleaned using a duster or a damp cloth
- Acidic, abrasive, or harsh chemical cleaners should be avoided during cleaning as they may damage the surface
- For exterior installations, joints and paint integrity should be inspected once a year
- The quality of the exterior paint is crucial to ensure protection against UV rays
- Exterior columns that accumulate dirt over time can be washed with low-pressure water and a soft sponge to restore their pristine, original appearance
Can rigid polymer spiral columns be used outdoors?
Yes, the P5840D column model is fully suitable for exterior use. Thanks to its closed-cell structure, it is moisture-resistant and helps prevent rot. However, to protect it from solar UV rays outdoors, it must be painted with a high-quality, UV-resistant exterior paint after installation.
Can we wrap existing concrete or iron pillars with this column?
Yes, the hollow design of this product is specifically engineered to aesthetically clad existing iron, steel, or concrete load-bearing pillars. The column is assembled in two halves around the existing post and secured using Polure Polfix adhesive.
Can the product be painted before installation, and is an extra primer required?
Painting before installation is not recommended as it will not cover the putty applications at the joints; the best practice is to paint after installation, screwing, puttying, and sanding. The factory primer prepares the surface for painting, but applying an additional primer coat is optional and depends on the user's preference in line with the paint manufacturers' warranty terms.
What are the advantages of polyurethane columns compared to plaster columns?
PU products are extremely lightweight compared to plaster, adding no static load to the building, and they carry a reduced risk of cracking or breaking upon impact. Unlike plaster, they do not absorb water and crumble over time, and their installation is much faster, cleaner, and effortless.
Which adhesive should I use for installation, and are screws mandatory?
Silicone must never be used during installation; only Polure Polfix adhesive should be preferred. For safety, given the product's volume and height, mechanical securing with screws at the top and bottom points is mandatory in addition to the adhesive.
