Shutter slat

A slat for use in a rolling shutter, comprising:

• a body having an upper edge and a lower edge, an outward facing side extending between the upper edge and the lower edge, and an inward facing side with a concave curve extending between the upper edge and the lower edge;
• an engaging track connected to the body at the upper edge, the engaging track comprising a hook that extends upward from the upper edge and the intersection between the engaging track and the body is a smoothly curved transition;
• and
• a receiving track connected to the body at the lower edge, the receiving track comprising a lip member having an outer lip surface and an articulating lip surface, the outer lip surface is contiguous with the inward facing side of the body and extending downward along the same curve as the inward facing side of the body to a curl, the curl extending upward to a tip;
• the receiving track further comprising a guard member spaced apart from the lip member and having an articulating guard surface, an articulation space wherein a second engaging track of a second identical slat may hook the lip member through an aperture between the lip member and the guard member to form a hinge, and a receptacle located between the lip member and the guard member that is separated from the articulation space by a first shoulder on the articulating lip surface and a second shoulder on the articulating guard surface,
• wherein the lowest point of the curl is horizontally displaced from the intersection of the second engaging track and body of the second identical slat.
