Polyurethane Decorative Round Curved Arch Models

The design coded P1456D135VIA is an exclusive decorative element that brings arched transitions—one of the most majestic features of traditional architecture—into modern living spaces. Creating a soft and aesthetic transition between spaces with its semi-circular form, this product stands out with its central seashell motif and symmetrical leaf carvings. It adds depth and character to structures, whether used in interior door and hallway transitions or above exterior windows.

Manufactured from high-density rigid polyurethane (rigid PU) at 150-220 kg/m³, this arch offers a hardness comparable to wood. With a depth of 26.7 cm, a span width of 175 cm, and a height of 108.2 cm, it has the ideal dimensions for wide doorways and standard exterior windows. Include the product weight and fixing loads when assessing the substrate and supporting structure. Its closed-cell structure prevents water absorption, providing superior resistance to moisture, humidity, and rot.

As seen in the visual, the body of the product features stepped, smooth-profiled curved lines. The neoclassical-style seashell relief positioned at the very peak of the arch—the keystone area—combines with a spiraling pearl string and leaf reliefs below to offer a rich visual appeal. Delivered with a factory-applied white primer, the smooth surface provides an excellent base for the final coat of paint.

Boasting a wide range of applications, this architectural element is highly favored for luxury residential entrances, hotel lobbies, and spacious living room transitions. On exterior facades, it pairs beautifully with window jambs to add dynamism, while indoors, it serves to divide hallways or frame wall niches. Unlike wood or plaster, it does not crack or attract pests, offering a major advantage for long-term durability.

During installation, Polure Polfix adhesive should be applied to the cleaned surface, followed by mechanical fastening with stainless steel screws. Once the joints are filled with suitable putty and sanded smooth, the painting process can begin. Although the factory primer enhances paint adhesion, applying an additional primer coat is optional and depends on the user's preference to meet paint manufacturers' warranty terms. For outdoor applications, UV-resistant paints must be used to protect the material from sunlight degradation.

For architects and homeowners looking to combine the noble lines of historical eras with the advantages of modern engineering, this curved model is a smart investment that delivers both durability and aesthetics. With its easy-to-clean, maintenance-free structure, it retains its original form for many years to come.
