Polyurethane arch segment
Polyurethane arch segment refers to a curved architectural molding component engineered to construct, frame, or detail arched portals, radius windows, curved wall transitions, and interior passageways. Widely specified in hallway colonnades, decorative wall alcove surrounds, and Classical exterior facade accents, it establishes refined visual boundaries. Manufactured from high-density rigid polyurethane, it features an ultra-lightweight cellular core that places zero stress on surrounding drywall or masonry framing while bonding rapidly with adhesive. Completely impervious to ambient moisture and liquid water, it functions reliably across damp spa spaces or harsh exterior environments without cracking or delaminating. Its hard surface repels impacts while factory primers effortlessly accept acrylic topcoats.
