Jump to additional Rolling Steel Door offerings:
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 Door Sizes: 30' wide, 30' high standard construction. Large Openings to 50' wide, 40' high, consult factory.
Rolling Door Operation: Motors, chain, hand-crank or push-up designs based on size, weight or frequency of operation.
Usage: Standard construction for coiling doors is up to 20 cycles per day with High Cycle Construction available for doors expected to be operated more than 20 cycles per day, i.e., parking garages, sally ports.
Fast Acting Doors: For high traffic openings or where air flow or temperature control is critical, doors can be designed to operate at more than twice the speed of typical doors, or up to 2 ft./sec.
Seismic Performance Validation: Cornell can provide project specific seismic calculations for all coiling doors that are mounted Face of Wall or Between Jambs to steel or masonry. Seismic performance validation is per ASCE 7-05.
