Classic Polyurethane Decorative Corbel and Keystone Model

The P9003 keystone and corbel is a functional decorative element designed for use at the apex of windows, doors, or arches on both exterior facades and interior spaces. Measuring 22.1 cm in width, 25 cm in depth, and 32.1 cm in height, this exquisite piece adds three-dimensional depth to facades, accentuating a classic architectural identity. Enhancing the overall character of any building, this solid element effortlessly integrates the majestic presence of historical structures into your modern projects.

Its visual design features elegant spiral volutes at the top and a symmetrical bead-and-reel motif cascading down the center. In the lower section, these details merge with finely crafted acanthus leaf reliefs and smaller scrolls, presenting an exquisite example of neoclassical and Baroque styles. Thanks to Polure's high-precision molding technology, every single pattern line on the product is sharp, smooth, and highly defined.

Technically, the product is manufactured from high-density rigid polyurethane with a density of 150-220 kg/m³. This durable structure, matching the hardness of wood, offers high resistance to impacts and harsh weather conditions, while its lightweight nature ensures zero static load on the building's structural systems. Furthermore, it retains its form perfectly in temperatures ranging from -20 °C / +70 °C, and with a water absorption rate of less than one percent, it remains resistant to moisture, rain, or rot.

The product is delivered pre-primed with a factory-applied undercoat. This factory primer facilitates better adhesion of the topcoat; however, additional primer applications for paint manufacturers' own system warranties are optional and entirely at the user's discretion. Polure does not assume responsibility for the performance of applied paints. For exterior installations, UV-resistant topcoats must be used to prevent the material from yellowing under sunlight.

Unlike fragile traditional plaster or flimsy EPS foam, this durable polyurethane decorative product guarantees long-lasting use. During installation, the product must be secured to the surface using Polure Polfix adhesive and mechanically reinforced with screws. Once joints and screw holes are filled with exterior putty, sanded, and painted, a flawless finish is achieved.
