Wind Rated Garage Doors »

In high wind and cyclonic areas, it’s sometimes necessary to engineer your garage door a little differently to ensure it withstands the particular stresses it may be subject to. Our wind-rated garage doors are ideal for homes, sheds, and commercial and industrial warehouses in high wind-prone areas.
