Powder-coat finishes are more durable and chip-resistant than paint, so it was a smart move on Bilco's part to start offering a factory-applied polyester powder-coat finish as an option for its Classic Series steel basement doors. Powder Coat Finished Basement Doors come in four colors - white, sandstone, light gray, and brick - and cost $150 more than the company's standard factory-primed Classic Series doors.
