Keystone Door Arch

A keystone door arch is a decorative architectural element designed to frame door openings with an elegant, prominent keystone motif at its apex. Perfect for adding depth and classic visual detail to interior room transitions, hallways, and exterior entrance doors. Crafted from high-density polyurethane, these arches are exceptionally lightweight compared to traditional plaster or stone, putting zero structural load on your walls. Highly resistant to moisture, water, and physical impacts, our polyurethane arches maintain their shape without cracking, peeling, or blistering, even in harsh outdoor conditions. They can be easily painted with any water or solvent-based paint and installed quickly using specialized adhesives and screws. Polure offers premium-quality keystone door arches with millimetric precision and a smooth finish for long-lasting elegance.
