An end wall panel for an arch-style steel building is disclosed. The end wall panel is fabricated from metal sheet and consists of a plurality of upper flanges spaced apart from one another. The upper flanges are connected to lower flanges by a web section extending at an angle from the upper flange. Flange stiffeners also extend at an angle from the outermost upper flanges. The end wall panel provides increased strength in an arch-style steel building and can withstand critical wind loads without additional stiffeners. The end wall panel is also inexpensive to manufacture and install into an arch-style steel building.
