The DBCI Advantage We are a leading manufacturer of commercial-grade steel doors, components, and accessories. For over 25 years, we have partnered with our customers to deliver durable, high-quality products backed by distinguished customer service and an enduring commitment to excellence. The backbone of the DBCI product line is our roll-up door. We were among the first manufacturers to dedicate resources to the commercial roll-up product category, and today we remain an influential leader in the market. Utilizing an in-house wind-testing facility and cutting-edge equipment, we manufacture our doors to the highest possible standards. DURABLE CURTAINS Our curtains are manufactured with Grade E steel. We offer light-duty, heavy-duty, and wind-certified doors in 11 standard colors and 13 non-standard colors for any application. LONG-LASTING SPRINGS Springs are the most critical mechanical component of a steel curtain roll-up door. DBCI uses only oil-tempered, torsion-type springs for its doors to help ensure longevity of use with minimal maintenance. INNOVATIVE CORRUGATED DRUM DESIGN Our unique and innovative corrugated drum design provides superior cycle operation, improved sound control, and a more seamless aesthetic appearance when compared with industry-standard alternatives. The DBCI corrugated drum fits flush with the sheet, enabling the door to roll-up quickly and quietly with each use to save you time and effort.
