Rolling Doors

Service Doors

Heavy Duty. . . the only kind of Rolling Service Door we offer, built by Cookson. Every service door includes: 50,000 life cycle design, structural angle guides and bottom bar, fabricated steel plate brackets, cast gears and stops, 20 psf windloading and our exclusive FinalCote finish. The Cookson family has spent 60 years manufacturing premium rolling door products that have endured the test of time.

Security Grills

Cookson Rolling Grilles are an example of our uncompromising commitment to quality and value. They have been manufactured with the same proven materials and designs for decades. The grille curtains are still made of 5/16″ solid aluminum rods rather than hollow rods and the links are still 1/8″ or 3/16″ thick aluminum shapes rather than thinner gauge materials. The aluminum extruded guides and bottom bars are still made of heavy-walled shapes. You can buy a cheaper grille, but you can’t buy a better grille.

Insulated Rolling Doors

Cookson knows insulated doors. Choose our market-leading energy-efficient insulated doors in extreme environments or anywhere you want to save on energy costs and go green.

Fire Rated Doors

Our fire door systems are the clear and reliable choice for building owners and designers who demand the highest level of life safety and fire protection available with the lowest cost of ownership in a modern, easily integrated package.

Fire Doors

Property protection – Occupancy Safety – Functionality

Our Cookson fire door systems are the most reliable choice for those who demand the highest level of life safety and fire protection available with the lowest cost of ownership in a modern, easily integrated package. In order to limit damage caused by fire, Cookson also recommends that all fire doors be actuated by smoke detectors or building alarm systems. Cookson’s Auto-Test™ Fire Door Products Systems have been specifically designed for smoke detector or building alarm actuation.

Counter Shutters

A solution for strict dimensional limitations around the header or where aesthetics are required, Cookson’s Auto-Test Tube Motor Operated Counter Fire Door’s motor is located within the shaft assembly to neatly conceal the operator and drive components. Upon activation, it will close without losing spring tension or disengaging the operator drive mechanism, providing simple testing and resetting of the closing system.

Auto-Test Chain, Crank, and Motor Operation
Provides a controlled rate of descent not to exceed 12″ per second upon activation of the buildings’ fire alarm system or local detector. Ideal for applications requiring frequent testing or when it is difficult to access the operating mechanism, these doors will not release spring tension and can be tested frequently from floor level by facility personnel.

Simple-Test Chain, Crank, and Motor Operation
These counter fire doors are better suited when connection to an alarm system or local detector is not required. These fuselink activated doors do not release spring tension upon activation. Chain and crank applications are ideal when power is not available at the opening.

Push-Up Operation
The same fire protection you would expect from a Cookson Fire Door in a compact, push-up operated, counter door design. Fuselink activation initiates controlled door closure by releasing spring tension.
