High-Performance Doors & Grilles

Our Extreme® High-Performance Products offer advanced performance where you need it most. Whether you need advanced performance for security, productivity or air protection at the opening, we can suggest the right door or grille to meet your performance needs.


High-Performance Commercial Closure Solutions

When it comes to speed and durability, our high-performance commercial doors are in a class all their own. These high speed closures operate faster than traditional rolling doors while offering low maintenance demands and exceptional life cycles. We manufacture custom high-performance rolling doors and security grilles suited for a range of commercial uses, ranging from a parking garage to a busy loading dock

Regardless of the size or scope of your business, Cornell has a solution to match your needs. Our high performance roll up doors offer benefits any business owner can take advantage of, including:

  • High-Speed: These doors and grilles are manufactured to move — operating at 24 inches per second — increasing productivity and security and reducing the risk of a vehicle collision.
  • Reliability: Our high-performance closures require little ongoing maintenance and are guaranteed to last anywhere from 300,000 to 1,000,000 operating cycles depending on the product. 
  • Efficiency: Fast operation means less demand on your HVAC system to balance your climate. 


"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."
