The weldable sheet pile according to the invention has a first flank ( 12 ), wherein a preformed weld end ( 26; 90 ) is constructed on the longitudinal edge of said first flank [( 12 )] to be welded onto a sheet pile wall component ( 62 ) of the arrangement ( 50 ), has a second flank ( 14 ), wherein an interlock ( 30 ) is formed on the longitudinal edge of said second flank [( 14 )] for the purpose of linking into the interlock of a further sheet pile wall component of the arrangement ( 50 ), and has a center web [( 16 )] which runs in a straight line and which connects the two flanks ( 12, 14 ) to each other. The center web ( 16 ) runs at an angle to each of the two flanks ( 12, 14 ), as viewed in the cross-section of the weldable sheet pile ( 10 ), in such a manner that the weldable sheet pile ( 10 ) is substantially z-shaped in cross-section.
