Maximum security doors provide immediate protection in the face of danger by automatically closing. Activating a lockdown will automatically close the overhead safety doors.

Wind load rated doors and Hurricane rated garage doors from Cornell automatically secure the door inside the guides to prevent door blowout.


The events in today’s world have pushed the need for maximum protection to secure properties in the cases of attacks, riots, break-ins along with natural disasters such as hurricanes and weather events. We’ve developed this safety door program to address requests for advanced security closure solutions that have come directly to us due to recent events of riots and vandalism to storefronts around the country. The demand for high-security doors is not just from government buildings, but big box retail stores, high-end electronic chains, and large home improvement stores but now small local stores and buildings are all demanding high-security overhead doors too.

High security means not only property protection but fast protection for employees and customers too. Designed for maximum security in any type of solutions, Cornell’s maximum steel security doors feature the securest features available for commercial security doors. Features such as quick lockdowns, central door deployment using a “lockdown button” and custom specifications make Cornell’s security doors the first choice. Just because our overhead security doors are the strongest and most secure overhead door does not mean that you have to sacrifice looks. All safety doors are custom manufactured to not only protect but to still offer Custom branding, full-color graphics, multiple powder coat choices or even different materials such as stainless steel to meet your security door needs.


The increased devastation due to hurricanes has risen greatly over the last few years, causing the need for specific wind load rated and hurricane impact doors. Catastrophic building damage occurs when substandard commercial doors fail to resist the wrath of a recent hurricane. This proves that all garage doors are not equal when it comes to withstanding hurricane-force winds. However, making sure commercial door construction truly meets a building’s wind load needs can be a challenge to architects and building owners. Cornell is ready to help make sense of these confusing criteria and provide the right product to meet your project’s wind load requirements. Whether it’s an impact rated garage door, wind load rated garage doors or hurricane proof garage doors, Cornell has the right hurricane doors to meet your overhead door solution.

All specified wind load ratings are validated by third-party testing and have been tested to perform when mounted to steel, concrete, and CMU to provide the correct wind rated garage doors for the correct installation. When it comes to the safety and security of your building, especially in extreme conditions, you can trust Cornell's rolling door expertise and more than 175 years of experience.


Wind Load

We are proud to offer one of the most comprehensive line-ups for wind load design. Our overhead service doors, insulated doors, and fire doors can be configured to withstand the full range of specific wind load requirements including missile impact ratings. Specified wind load ratings are available when mounting to steel, concrete, and CMU, and have been validated through third-party testing to one or more of the following performance criteria:

  • ANSI/DASMA-108
  • ASTM E 330
  • Miami-Dade County test protocols TAS 201, TAS 202 and TAS 203
  • Florida Building Code (FBC)
  • Texas Department of Insurance (TDI)
  • Signed and Sealed Calculations

If you know only the wind speed and a couple of the other variables for determining the required wind load, the DASMA website's wind load calculator determines the approximate psf requirements--this should only be used as a guide. Our team can help find the perfect hurricane impact doors for any solution or situation.

In order to determine the exact psf requirements, the following variables are required: wind speed (in mph), exposure category, door area, mean roof height, roof slope, directionality factor, surrounding topography, zone, positive or negative pressure and internal building pressure.


If you need further assistance, our Architectural Design support team can help you in translating building codes or determining the appropriate wind load. Contact us to discuss your hurricane proof garage door project.
