An improved Z-shaped sheet piling ( 15 ) comprising a first flange ( 16 ), a second flange ( 18 ), a web ( 19 ), a junction ( 20 ) between the first flange and the web, the junction having an inner surface ( 44 ), the inner surface defined by at least a first radius ( 23 a) and a second radius ( 23 b). The inner surface may be further defined by a third radius ( 23 c). The sheet piling may comprise a first flange ( 16 ) having a substantially planar flange surface ( 37 ), a second flange ( 18 ), a web ( 19 ) having a substantially planar web surface ( 39 ), a junction ( 20 ) between the first flange and the web, the junction having a fillet portion ( 43 ) defined by the planes of the web surface and flange surface extended to an intersection ( 59 ) and an inner substantially arcuate surface ( 44 ) intersecting the web surface and flange surface, the inner arcuate surface defined by at least a first radius ( 23 a) and a second radius ( 23 b). The inner arcuate surface may be further defined by a third radius ( 23 c).
