ABSTRACT:
A hot-rolled Z-shaped sheet pile comprises two flanges (12', 12") and a web (10) delimited by two substantially plane faces (18', 18"). This web (10) makes an acute angle 75o with a plane (16) parallel to the outer faces (14', 14") of the flanges (12', 12"). In order to increase the section modulus of this sheet pile without having to increase the thickness of the flanges (12', 12") or the rolling width, each of the two flanges (12', 12") has an extension (22', 22") protruding with respect to the fictitious plane (24', 24") extending the plane face (18', 18") of the web located on the same side as the outer face (14', 14") of the respective flange. In this way, it is possible to roll sheet piles having a section modulus per unit length of the wall 4800 cm3/cm and a specific section modulus of approximately 20 (cm3/m)/(kg/m2).
