Designation of steel grades

Hot-rolled steel sheet piles must comply with DIN EN 10248. The following table lists various hot-rolled steel grades for sheet piles; steel grades S 270 GP and S 355 GP are generally used. The choice of steel grade depends on structural aspects, the method of driving selected, the embedment depth and the ground conditions. Steel grades for hot-rolled steel sheet piles and their characteristic mechanical prop- erties to DIN EN 10248-1

 

Steel grade Min. tensile strength
fu[N/mm2]
Min. yield strength
fy[N/mm2]
Min. elongation at failure
εu[%]
S 240 GP 340 240 26
S 270 GP 410 270 24
S 320 GP 440 320 23
S 355 GP 480 355 22
S 390 GP 490 390 20
S 430 GP 510 430 19

 

The characteristic mechanical properties of cold-worked steel sheet piles according to DIN EN 10249-1 are shown in table 2.2. These sheet piles are used, for example, when a lightweight section is required or for trench sheeting. The following table shows Steel grades for cold-worked steel sheet piles and their characteristic mechanical properties to DIN EN 10249-1
