Round Arch with Keystone

A round arch with a keystone is a decorative architectural element featuring a semi-circular arch design with a prominent keystone detail at its apex. It is widely used to create an aesthetic focal point in interior room transitions, hallways, niche designs, and arched building entrances. Manufactured from high-quality polyurethane, it does not add any static load to the building structure, unlike heavy plaster or marble alternatives. Offering high impact resistance, this durable product does not warp, swell, or rot in humid environments. It can be easily sanded and painted with any type of interior or exterior paint. Thanks to its lightweight nature, it is quickly and easily secured to surfaces during installation using specialized adhesives like Polure Polfix. Polure guarantees long-lasting durability by producing keystone round arches with smooth surfaces and sharp details using advanced precision molding technology.
