The P1461D530VI is a premium polyurethane architectural element specifically engineered to create monumental transition zones and grand archways in high-end design projects. Ideal for wide doorways, tall windows, and majestic portal passages, this curved decorative arch brings the timeless aesthetic balance of classical architecture to any space. Thanks to its lightweight composition, it can be safely integrated into large-scale restoration and new construction projects while putting only a limited load on the building. Suitable for both interior and exterior applications, this product ensures long-term structural stability.
The physical profile of the product stands out with its monumental dimensions of 150x6019x3010 mm. This massive scale offers perfect proportions, particularly for high-ceilinged lobbies or expansive villa facades. Manufactured from high-density rigid polyurethane (150-220 kg/m³), this closed-cell material is highly resistant to moisture, rot, and insect damage, unlike traditional wood or plaster alternatives. It retains its pristine form for decades under harsh outdoor conditions, while its crack-resistant and non-shrinking properties minimize maintenance costs.
Visually, the design showcases a perfect harmony between its stepped outer profile lines and the smooth, flat inner curved surface. This elegant yet deep profile structure catches light and shadow beautifully, accentuating the circular form of the arch. Its clean design allows it to blend seamlessly into a wide range of decor styles, from modern spaces infused with classical elements to historical landmarks. The flawless surface quality guarantees a perfectly smooth finish after painting.
Highly versatile in application, this large circular polyurethane arch is frequently utilized in hotel reception passages, luxury restaurant dining rooms, open veranda portals, and as elegant pediments over wide residential windows. With a water absorption rate of less than 1%, it delivers outstanding performance without warping or cracking, even in high-humidity areas like bathroom entryways or under exterior eaves. It serves as the ideal architectural solution for achieving aesthetic cohesion across wide openings.
During installation, Polure Polfix adhesive should be applied to a clean, dry surface, and due to its large dimensions, mechanical screw fastening is absolutely required. The product arrives factory-primed and ready for paint; however, depending on the paint manufacturer's warranty requirements, an additional primer coat can be optionally applied. For exterior applications, using UV-resistant paints will maximize the product's lifespan. Once joints and screw holes are filled with a suitable putty, they can be sanded smooth and painted.
- The P1461D530VI large curved arch is an exceptional choice for creating grand passageways in both interior and exterior designs
- Indoors, it is used to craft arched portals in hotel lobbies, spacious villa living rooms, restaurant entrances, and hallway transitions
- Include the product weight and fixing loads when assessing the substrate and supporting structure
- Externally, it serves as a sophisticated framing element around main entrances of luxury residences, above wide arched windows, and on open veranda transitions to add depth and classical character to the facade
- Assess water and moisture exposure using the product technical data, surface finish and installation details
- Spanning nearly 6 meters, this massive curved structure creates a monumental focal point on the facades of large-scale commercial buildings and historical restoration projects
- Unlike wooden alternatives, it does not warp or bend over time, maintaining its structural integrity across wide spans
- Ensure that the curved surface to be installed is completely dry, clean, and free of dust
- Given the large dimensions and weight of the product, Polure Polfix adhesive with high bonding strength must be applied to the back surface during installation
- In addition to chemical bonding, it is mandatory to use screws at regular intervals to mechanically secure the arch to the wall
- Screw heads should be slightly countersunk into the surface
- After installation, screw holes and joints are filled with high-quality acrylic putty
- Once the putty dries, the surface is smoothed using 180-220 grit sandpaper
- An optional additional coat of primer can be applied over the factory-applied primer according to the paint manufacturer's recommendation, followed by at least two coats of water-based or synthetic paint to complete the process
- The polyurethane curved arch is an extremely durable product requiring minimal maintenance, thanks to its closed-cell structure
- For interior spaces, accumulated dust can be easily wiped away with a damp cloth; abrasive or harsh chemical cleaners should be avoided
- For arches used on exterior facades, an annual inspection of the painted surface is recommended
- In outdoor applications with direct sunlight exposure, a protective paint touch-up can be applied every few years if necessary to maintain UV protection
- Thanks to its low water absorption, dust and dirt on the facade can be effortlessly cleaned by spraying low-pressure water
Will it be affected by rain and sun when used on exterior facades?
Yes, the rigid polyurethane raw material has a closed-cell structure with a water absorption rate of less than 1%. This ensures it is highly resistant to outdoor elements like rain, snow, and humidity, helping prevent rotting or swelling. However, since UV rays from the sun can cause yellowing on unpainted polyurethane surfaces, it must be coated with a high-quality, UV-resistant exterior paint for outdoor applications. When properly painted, it retains its original form for decades.
Which adhesive should be used for installation, and are screws mandatory?
Polure Polfix polyurethane adhesive, which provides excellent adhesion and flexibility, must be used for installation; standard silicone adhesives are not suitable for this product. Additionally, due to the extremely large and monumental dimensions of this 150x6019x3010 mm arch, mechanical screw fastening is mandatory during installation for safety. The screws hold the product secure until the adhesive cures, reducing the risk of sagging or shifting over the long term.
Is it mandatory to apply a primer before painting the product?
The product is shipped with a special factory-applied primer coating. This factory primer facilitates paint adhesion to the surface. However, paint manufacturers do not guarantee paint jobs done without their own primer products. Therefore, applying an additional primer coat before painting is completely optional and left to the customer's preference. Polure does not accept responsibility for the performance of paints and external primers used.
What are its advantages compared to plaster or wooden arches?
Compared to plaster arches, this product is extremely lightweight, carries a low risk of cracking or crumbling, and is much faster to install. Unlike wooden arches, it is moisture-resistant, helping reduce the risk of warping, cracking, rot, or insect damage over time. It also offers functional decorative benefits. It is not soft or fragile like EPS styrofoam products; with a density of 150-220 kg/m³, its hardness is close to wood, making it highly impact-resistant.
Can the dimensions of the arch be adjusted to my project, and can it be cut?
Yes, this polyurethane arch can be easily cut using standard woodworking tools, miter saws, or hand saws. You can shorten its length by cutting the ends according to your project dimensions, or seamlessly join the connection points using Polure Polfix adhesive and putty. Once the cut and joined areas are puttied and sanded after installation, a seamless, single-piece, flawless curved appearance is achieved.
