Abstract

On a corrugated panel 3'a of the abovementioned type, provided with an end part 9' which is to constitute a main corrugation 11' by leaktight assembly with the corrugated end 10' of the adjacent corrugated panel 3'd providing the corrugations 8, the invention consists in equipping this end part 9' with secondary stiffening corrugations 16, which can advantageously be formed by folds produced at the same time as the main corrugations 8 on the same tool.
