A roller shutter door comprised of a plurality of horizontal panels with interengaged curled longitudinal edges to provide hinge action between the panels. There are strips of resilient material under a compressive load in the hinge joints to substantially eliminate slackness in the hinge joints. The invention also provides a method of assembling such doors, the method involving inserting a strip of resilient material in the curl of a first panel and applying a longitudinal load to the material to cause it to adopt a reduced cross-sectional size followed by the longitudinal insertion of the curl of a second panel into the curl having the stressed material therein and then releasing the load on the material to allow it to urge the curls of the interengaged panels into firm contact one with the other.
