Polyurethane Round Arch Model with Oyster Shell Motif

The product with model code P1456D160VIA is an exclusive decorative element that combines the classic arch form—one of the most striking features of traditional architecture—with modern engineering. With its smooth, semi-circular curved structure and an oyster shell-figured keystone motif at its apex, it lends a noble character to any building. By creating a sense of depth in doorways, window tops, or wide corridors, it transforms ordinary wall transitions into monumental architectural focal points.

Measuring 267 mm in depth, 1980 mm in width, and 1197 mm in height, this product perfectly accommodates wide openings. Manufactured from rigid polyurethane raw material, this curved arch features a density of 150-220 kg/m³. This specific density provides the product with wood-like hardness and exceptional impact resistance. Compared to traditional materials like plaster, it is remarkably lightweight and does not impose unnecessary static loads on the structural systems of buildings.

In terms of visual design, the smooth and stepped profile lines of the arch are balanced by highly detailed, handcrafted-looking features at the apex. The leaf and bead-and-reel embellishments beneath the oyster shell motif embody all the elegance of the classic neoclassical style. Produced under high pressure in custom steel molds, it guarantees that the curves and ornamental details remain millimetrically sharp and smooth at every point.

Offering a versatile range of applications, this design can be safely used for both interior and exterior spaces. Indoors, it is ideal for enhancing the perception of volume in grand salon entrances, hotel lobbies, and restaurant transition corridors. On exteriors, it elevates the architectural value of the building when used on main entrance portals, wide window pediments, or veranda openings. Thanks to its closed-cell structure, its water absorption rate is below 1%, keeping it completely free from moisture, mold, and decay.

Compared to traditional wood or plaster arches, its installation is extremely fast and practical. The factory-applied primer coat on Polure polyurethane products prepares the surface for painting; however, since paint manufacturers often recommend their own primers, applying an additional primer is entirely optional. Secured to the surface during installation using Polure Polfix adhesive, the product is mechanically supported with screws. For exterior applications, UV-resistant paints must be used to protect against the effects of sunlight.
