摘要
The present invention relates to a hot-rolled Z-shaped sheet-pile being comprised of two wings (12', 12'') and a web (10) delimited by two substantially planar faces (18', 18''). The web (10) defines a sharp angle alpha being less than 75 degree with a plane (16) parallel to the external faces (14', 14'') of the wings (12', 12''). In order to increase the resistance modulus of said sheet-pile without having to increase the thickness of the wings (12', 12'') or the rolling width, each of the two wings (12', 12'') has an extension (22', 22'') projecting with respect to the imaginary plane (24', 24'') which prolongs the planar face (18', 18'') of the web situated on the same side as the external face (14', 14'') of the respective wing. Thereby, it is possible to roll sheet-piles having a resistance modulus per wall length unit greater than 4800 cme3/m and a specific resistance modulus of about 20 (cme3/m)/(kg/me2).
