Decorative Polyurethane Round Arch Design

The architectural element model P1456D135VID blends classic circular forms—one of the most distinguished elements of traditional architecture—with modern manufacturing technology. Designed to create structural depth over doorways, hallway passages, and window tops, this round arch brings a balanced architectural harmony to any space. The central keystone detail adds a touch of traditional stonemasonry, beautifully balancing the visual weight of the design.

With a profile depth of 170 mm, an outer width of 1750 mm, and a vertical height of 971 mm, its technical dimensions offer ideal proportions for wide openings and high-ceilinged spaces. Manufactured from high-density rigid polyurethane (150-220 kg/m³), this model provides wood-like durability while remaining lightweight to avoid adding structural load. Thanks to its closed-cell structure, its water absorption rate is under 1%, largely preventing swelling, rotting, or dimensional warping in humid environments.

Visually, the product features a smooth, flowing curve with stepped profile details that follow the circular line, capturing light and shadow beautifully. The trapezoidal keystone motif at the apex unites the curved lines from both sides, creating an elegant aesthetic focal point. A factory-applied white primer ensures the surface is ready for final topcoat paint applications.

Offering versatile applications, this arch model is highly favored for defining living room and hallway transitions indoors, as well as creating elegant partitions in hotel lobbies or restaurants. Thanks to its high resistance to water and weathering, it also serves as an excellent decorative window pediment on exterior facades. It adds a strong structural identity to both classic neoclassical facades and eclectic interior design projects.

Compared to traditional materials like plaster, marble, or wood, it offers significant advantages in terms of easy installation and impact resistance. During installation, using Polure Polfix adhesive and securing mechanically with screws is mandatory. Once screw holes and joints are filled with suitable putty and sanded, a flawless finish is achieved with a topcoat of paint. For outdoor applications, UV-resistant paints should be used to protect the material from sunlight.
