Abstract
A main slat for a roller shutter system is provided. The slat includes a slat body having a first and second end, a hook end connected to the first end of the slat body, a screw boss connected to the second end of the slat body, and a receiving end connected to the screw boss. The hook end and the receiving end are each shaped such that the hook end is laterally insertable into the receiving end of an adjacent main slat and when so inserted forms a hinge. The slat body has a central cross section including at least first and second portions, the first and second portions each having a different radius of curvature.
