Coiling Doors

Commercial-grade steel curtain roll-up doors are designed and manufactured for strength and durability.

Curtain

DBCI's commercial doors are manufactured with hard, Grade E steel ensuring strength and durability. A siliconized polyester finish replaces older polyester paint finishes, which are recognizable by severe chalking and fading from direct contact with UV rays. DBCI steel curtain roll-up doors are coated with a silicon polyester paint highly resistant to UV light rays allowing some colors a warranty of up to 25 years.

A.C.E. Guides System

The A.C.E. (Advanced Curtain Engagement) guide system has been designed to benefit DBCI's customers. Some of the benefits include universal mounting options, increased durability, excellent performance and ease of installation. Through countless hours in the design room, DBCI has created one of the most advanced rolling sheet door guide systems in the industry.

Axle-Drum Assembly

DBCI's commercial door axles and drums are manufactured with industrial-grade steel. The door drums are designed and engineered specifically for commercial application to ensure product integrity, long life and high-capacity use. Steel ball bearings are preferable to nylon or plastic bushings, which can disintegrate under heavy use.

Vision Panel

Constructed of a translucent flexible polycarbonate, the 5" x 17" vision panel allows light entry and provides outside visibility. The white 20-gauge frame is pop-riveted and is normally installed approximately 55" from the floor. The location and number of panels per door is limited.

Springs

Springs are the most critical mechanical component of a steel curtain roll-up door. For maximum reliability, DBCI uses only oil-tempered torsion-type springs for its commercial grade steel curtain roll up doors. Coordinating the design of a roll-up door with the proper spring assembly ensures longer and more durable use with minimal maintenance required. In independent tests, DBCI's commercial-grade steel curtain roll-up door exceeded 40,000 openings and closings before any maintenance was required. Although there is no such thing as a maintenance-free door, at DBCI we engineer our roll-up doors to be maintenance-simple: easily visible for inspection and accessibility.

Wind Load Certification

Fueled by the constant changes in local and national building codes, as well as increasing insurance costs, choosing a door with a validated wind certification can dramatically reduce maintenance and replacement costs. The in-house wind certification facility enables us to manufacture doors to the highest standards. DBCI's commercial door 5000 Series, wind certified doors are designed to meet stringent building codes in coastal regions and Florida.
