1. A slat for use in a rolling shutter, comprising:
a body having a first edge, a second edge, an outward facing side extending along a convex curve between the first edge and the second edge, and an inward facing side extending along a concave curve between the first edge and the second edge; a engaging track connected to the body at the first edge, wherein the engaging track comprises a tip member, the tip member having an outer surface contiguous with the outward facing side of the body and an inner surface contiguous with the inward facing side of the body, the tip member disposed at an acute angle from the inward facing side of the body; and a receiving track connected to the body at the second edge, wherein the receiving track comprises a lip member having an outer lip surface and an articulating lip surface, the outer lip surface being contiguous with the inward facing side of the body, a guard member spaced apart from the lip member, the guard member having an outer guard surface and an articulating guard surface, an articulation space wherein a second engaging track of a second slat may hook the lip member through an aperture between the lip member and the guard member thereby forming 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 outer lip surface comprises a first lip surface, a first curved lip wall, a second curved lip wall, and a second lip surface, and the outer guard surface comprises a sloped guard wall and an outer guard wall, with the first curved lip wall and the sloped guard wall having a substantially similar curvature so that the first curved lip wall of a first slat can be aligned substantially flush with the sloped guard wall of a second slat. |
