Hurricane Proof Doors

Not all roll up doors are designed to take on Mother Nature. Cornell’s hurricane proof doors and wind load rated doors are! With the increased damage records becoming a regular occurrence, we have specifically engineered overhead steel coiling garage doors designed for just that. With many years of development to show, our hurricane rated doors have been designed to meet the requirements of ANSI/DASMA-108,  ASTM E 330, Miami-Dade County test protocols TAS 201, TAS 202 and TAS 203, Florida Building Code (FBC) as well as the Texas Department of Insurance (TDI). Our wind load rated overhead doors take into consideration Design Load Determination, door mounting and fastening methods along with specific door guide gaps. Each and every hurricane garage door is specifically calculated to where it will be installed. Other than the obvious wind load requirements, there are actually 10 other factors that play a role in determining Design Wind Load – a much more accurate measure of how a commercial garage door will be able to withstand a hurricane.
