The versatile Model 501 door can be engineered to meet various windload ratings. Our model numbers carry windload ratings listed in pounds per square foot of pressure (PSF). The actual miles per hour of windspeed resistance is a much higher number.

Creating a wind-resistant door involves several changes to the door design; such as.

  • Changing the gauge (thickness) of the steel guides used to mount the door to the building shell.   
  • Using a thicker steel in the door curtain.
  • Limiting the door width and height to create a stiffer door.
  • Utilizing side windlocks, or upgrading them from nylon to steel.
