What is the difference between Amarr and CHI?

Amarr and CHI Overhead Doors are both major US manufacturers, but they target different parts of the market. Amarr emphasizes value, broad selection, and brand recognition, with strong residential lines like the Classica carriage-house and a Costco partnership that drives volume sales. CHI emphasizes build quality and is preferred by professional installers who want a heavier, more durable door. CHI uses thicker steel gauges on equivalent models, has a reputation for quieter operation, and offers strong full-view aluminum lines with powder-coated frames. Amarr typically costs 10 to 20 percent less than CHI for a comparably equipped door. CHI also leads on commercial and high-cycle doors. Pick Amarr for value and the Classica look. Pick CHI for longer service life and modern aluminum designs.
