Usage

These doors are constructed for continuous use and are warrantied up to 300,000 cycles (or two years). Need more than 300,000 cycles, but less than a million? This door can be upgraded to offer 500,000 cycles with a 3 year warranty.

If you have an opening that only needs standard cycles, meaning less than 20 cycles per day, please consider our standard service or insulated product lines.

Standard Materials & Finishes

Extreme® 300 Series Performance Doors come with a unique and lasting powder coat finish customized for high-cycle usage as standard. There are two material options for both the service and insulated curtain:

Galvanized steel:
- Finished with a rust-inhibiting CycleShield® finish in Gray, Tan or White
- The CycleShield finish for High Performance Doors. The base coat is consistent with ASTM A653, and is finished with a baked-on polyester powder coating. CycleShield is:
  - Friction and wear-resistant for high-cycle applications
  - Rust inhibiting and resistant to acids, alkalis and oils at normal temperatures
  - Recommended for exterior, corrosive and/or abrasive environments
  - Available as an option in a palette of more than 180 standard RAL colors
- For a more durable finish, upgrade to CycleShield® Ultra™ powder coat finish. It is a polyester-based, textured, wear-resistant clear coat that provides improved durability against deterioration and/or marring of the curtain during regular use.

Testimonials

Check Out How We've Helped These Clients With Custom Closure Solutions:

"We are very pleased with the performance of the Cornell doors. Throughout the area, doors are blown out everywhere and the building we just moved from was destroyed. Here, our $2.3 million of inventory was saved. Being satisfied with the Cornelldoors is an understatement!"

ROGER WEIR, OPERATIONS MANAGER AT LEWIS BEAR COMPANY

"CornellCookson had installed a rolling door for us in our old building. We used it all the time and it’s held up really well over the years. Calling them in again made perfect sense. We are thrilled with how this door looks. The level of detail that’s been captured so clearly on this large door is incredible. It’s exceeded our expectations by far and will definitely do its job as a focal point in our new building."

MARK WORMAN, OWNER OF GRAVEYARD CARZ

"The existing grilles we had installed prior could not stand up to the cycle usage, and they needed a lot of maintenance. Cornell's Extreme Performance 324 grille is the right product, far superior to the other grilles we had in this opening before. We are really happy with the performance and will definitely purchase this product going forward, when the next opportunity arises."

MARK ARGABRIGHT, FACILITY MANAGER AT YOHN PROPERTY MANAGEMENT

"Not only was functionality a major concern, but we also needed a custom closure solution that worked with the overall exterior aesthetic of the building which is rooted in neighborhood context. We collaborated with CornellCookson to develop a solution that is both functional and architecturally sensitive."

EUGENE FLOTTERON, CETRARUDDY ARCHITECTURE

"The SteelWeave Metal Mesh Grille was the perfect solution to meet all of our needs. It complimented the design of the bar and lobby while adding some elegance. We could not be happier with the look and function of our CornellCookson SteelWeave Metal Mesh Grille and custom sliding panel."

DONALD FOX, FOX THEATERS
