A metal shutter with improved air and light transmission is provided. The shutter comprises a metal top, a metal bottom, and two metal sides, which can be collectively assembled into a frame. The frame can have a metal support column that can be affixed to the top and bottom. A number of metal slats can be affixed between the sides of the shutter, and can either pass through the center column or can be affixed to the center column. A hinge can be affixed to the top of the frame, and can also be affixed to a structure. The top, bottom, sides, support column, slats, hinge, and a lock all comprise the shutter. The hinge allows the shutter to rotate between a first, substantially vertical, position, and a second, non-vertical position. The lock holds the shutter to a structure when the shutter is in the first position.
