Rolling Steel Doors
Rolling Steel Doors are metal slatted doors that roll up to store in coil above the opening. They are used to provide security against entry or weather protection at exterior and interior openings in industrial, commercial, institutional and other buildings. They are also called overhead coiling doors or service doors.
Rolling Steel Door Benefits:
- Design Flexibility: Cornell coiling doors are built to order to fit your opening size, operation and option preferences.
- Space Saving: Coiling doors roll upward and store in a tight coil above the opening for fuller use of the interior space. This reduces interference with other building components.
- Low Life Cycle Cost: Cornell’s rugged construction and quality materials assure long life and less costly maintenance.
Rolling Counter Doors secure openings above counters and other similar finished openings on interior and exterior walls. Feature smaller, more aesthetically pleasing guides, slats, brackets and hood than rolling doors; can fully close to the floor when compact door components are desired. Also called shutters.
Sizes: Openings up to 21′ wide or 10′ high standard construction.
Operation: Concealed tubular motors, shown left, provide a solution for strict dimensional limitations around the header or aesthetic requirements that lend themselves to its smaller, compact design. Standard motor, hand crank, or push-up designs also available based on size and weight.
Materials and Finishes: Curtains available in #18 B & S gauge or extruded .055″ aluminum with clear or color anodized finish, 22 gauge galvanized steel with exclusive GalvaNex™ finish in light gray or 22 gauge stainless steel with #4 finish. SpectraShield® Powder Coating optional.

Coiling Fire Doors
Coiling Fire Doors are rated physical fire barriers that protect wall openings from the spread of fire. They provide automatic closing in the event of fire detection with governed speed control. Fire doors are also designed for daily use to provide security and access control, but are for use in openings that are not part of a required means of egress. Cornell offers a complete line of labeled rolling doors for protection in wall openings where rated doors are required by building codes and for insurance purposes.
