A continuous metal strip with turned-up lateral edges suited to creating a sealed membrane is obtained from a blank which along its length has a first, reinforced, end zone (114) having a first thickness and a second, central, zone (113) having a second thickness smaller than the first thickness. The metal strip across its width has a flat central zone and two lateral edges (13) which are bent substantially at right angles to the flat central zone, the two lateral edges being of small width in comparison with the flat central zone. Application to the creation of a sealed and thermally insulated tank built into a bearing structure comprising a plurality of bearing walls.
