Arbonia AG is a specialized European supplier of building components headquartered in Arbon, Switzerland. Historically a diversified industrial group, the company strategically refocused its operations in 2024 and 2025 by divesting its climate and windows divisions to concentrate entirely on its Doors business. Today, Arbonia manufactures a wide range of interior doors, door frames, sliding doors, and glass partition elements used in residential, commercial, and public buildings. The company operates multiple production sites across Switzerland, Germany, Poland, Spain, the Czech Republic, and Portugal. Its products are primarily distributed through project sales and trade partners to builders, architects, and contractors for both new construction and renovation applications.
