Abstract
A high strength window screen frame that includes an extruded metal frame that surrounds a window opening in a building. The frame defines an opening. A screen plate portion of the extruded metal frame is provided on the frame proximate the opening. A flange portion of the extruded metal frame is provided on an outside of the frame away from the opening. A beveled surface on the flanged portion is provided to improve the appearance of the metal frame. A screen plate stiffener is removably affixed to a back side of the extruded metal frame to secure a screen to the frame. Heavy duty mesh screen is preferably used with a high strength window screen frame of the invention. The flanged portion of the window screen frame is bolted to an exterior wall surrounding a window opening of a structure.
