What is a Roll-Up Door?
A garage door made of narrow slats that coil around a drum above the opening — common in commercial and industrial applications.
A roll-up door (also called a rolling steel door, coiling door, or sheet door) consists of narrow interlocking steel or aluminum slats that coil around a barrel assembly above the door opening. Unlike sectional doors that slide along horizontal tracks and park along the ceiling, roll-up doors coil into a compact roll, making them ideal for spaces with limited ceiling clearance or where the ceiling area is needed for storage, lighting, or HVAC equipment. Roll-up doors are most common in commercial and industrial settings: warehouses, loading docks, storage units, retail storefronts, fire stations, and parking garages. High-speed roll-up doors — which open at speeds of 24–48 inches per second — are used in high-traffic commercial environments where minimizing open time improves energy efficiency and security. Residential roll-up doors exist but are less common than sectional doors in Canada.
