Rolling Steel Doors

When space is at a premium and physical security is paramount, Overhead Door Commercial Rolling Steel Doors provide compact, heavy-duty protection for wall openings. At Timbers-Kovar, we supply and install these coiling steel service doors, engineered to roll vertically into a compact hood above the door header—maximizing valuable overhead ceiling space and floor clearance.

Designed for loading docks, manufacturing facilities, storage structures, and high-vibration industrial environments, rolling steel doors offer rugged durability and long-term security.
