Abstract
A slat for a rolling shutter is provided that is formed as a single walled, continuous bent sheet. The slat includes a body having a hook-shaped engaging track at a first end, and a receiving track at the second end comprising a guard member and a hook-shaped lip member that form a pocket for receiving the engaging track of another slat. The guard member includes a portion of the sheet that is bent over on itself. The lip member extends from the guard member, and is spaced apart from the guard member to define an aperture that is sized and shaped to receive the engaging track of the other slat.
