7.2.4 For all steel grades a copper-content between 0,20 % and 0,35 %, or between 0,35 % and 0,50 %
on the heat analysis (for different corrosion protection levels) can be agreed upon at the time of enquiry
and order. In both cases, the maximum carbon equivalent value of Table 1 shall be increased by 0,02.
See Option 3, Clause 13, (Cu alloyed).
7.2.5 When products of grades S270 to S355 are supplied with a control on Si, e. g. for hot-dip
zinc-coating, so that there could be a need to increase the content of other elements like C and Mn to
achieve the required tensile properties, the maximum carbon equivalent values of Table 1 may be
increased as follows:
— for Si ≤ 0,04 %, increase the value of the CEV by 0,02;
— for Si ≤ 0,25 %, increase the value of the CEV by 0,01.
7.3 Mechanical properties
7.3.1 General

Using test pieces of width less than 10 mm, the minimum values given in Table 3 shall be reduced in direct
proportion to the cross-sectional area of the test piece.
See Option 4, Clause 13, (Verification of impact energy).
7.4 Technological properties
7.4.1 Weldability
General requirements for arc welding of the steels shall be as given in EN 1011-2. In general, steel sheet
pile grades are suitable for arc welding.
NOTE 1 With increasing product thickness and strength level, cold cracking can occur. Cold cracking is caused
by the following factors in combination:
— the amount of diffusible hydrogen in the weld metal;
— a brittle structure of the heat affected zone;
— significant tensile stress concentrations in the welded joint.
NOTE 2 Steels specified in this document do not have unlimited suitability for the various welding processes,
since the behaviour of a steel during and after welding depends not only on the material, but also on the dimensions
and shape and on the manufacturing and service conditions of the components.
7.4.2 Flame straightening
Recommendations regarding flame straightening are laid down in CEN/TR 10347.

7.4.3 Hot-dip zinc-coating
EN ISO 1461 should be used to specify coating requirements. EN ISO 14713-2 provides further guidance,
including information on the influence of various factors, including steel chemical composition, on the
coating formation.
Option 5, Clause 13, can be used to order steels with a chemical composition required for hot-dip zinc
coating. When Option 5 is implemented, the purchaser and manufacturer shall agree to a steel
composition (heat analysis) of silicon and phosphorous according to either:
Category A (see also EN ISO 14713-2:2020, Table 1, Note 1); or
Category B; or
Category D (limited to 0,25 % < Si ≤ 0,35 %)
with required values as cited by the ranges given in EN ISO 14713-2:2020, Table 1, column 2.
NOTE EN ISO 14713-2:2020, Table 1, gives guidance on typical coating characteristics associated with certain
steel compositions on the basis of the surface composition of silicon and phosphorous.
The maximum carbon equivalent shall be increased by 0,02 or by 0,01 (see 7.2.5).
In some cases, steels above S460 may be sensitive to cracking during galvanizing and therefore special
care should be taken.
See Option 5, Clause 13, (Chemical composition for hot-dip zinc-coating).
7.5 Surface properties
EN 10163-1 and EN 10163-3 shall apply for the permissible surface discontinuities and for the repair of
surface defects by grinding and/or welding. Class C, subclass 1 of EN 10163-3 shall apply, unless
otherwise agreed upon at the time of the order.
The surface requirements and repair conditions of sheet piles shall apply to all surfaces excluding
interlocks and radii at the connection between web and flange.
See Option 6, Clause 13, (Other surface class).
7.6 Internal soundness
The internal soundness shall be in accordance with EN 10021.

7.8 Load bearing capacity
7.8.1 General
The design of steel sheet pile structures requires determination of the actions on the structure, for
example the earth pressure, the water pressure, the surface surcharge, etc., and the appropriate
resistances. The actions will give rise to effects all over the structure, for instance internal forces and
moments, stresses, strains and displacements. Additional local effects will also be produced for instance
at points of load applications. The resistances of the sheet piles to the effects of the loads shall be
determined according to EN 1993-5, if applicable. For applicability, reference can be made to Report
EUR 20034 EN (Development of unified design rules for steel sheet piles for introduction into
EN 1993-5). If a calculation method for a specific resistance is not applicable, the resistance shall be
determined by direct testing in accordance with EN 1993-5.
In general, the section resistance can be expressed as the product of the material strength for the chosen
steel grade and a specified geometrical section property dependant on the nominal dimensions of the
section. The rules for calculating the section properties from the nominal dimensions shall be in
accordance with normative Annex B.
7.8.2 Interlock resistance of straight web sheet piles
The interlock resistance of straight web sheet piles shall be agreed at the time of enquiry and order, and
shall be tested according to the conditions as specified in 9.2.4.
7.8.3 Resistance of crimped points of U-shaped sheet piles
Crimped points can be used to enhance the shear force transmission in the interlocks of U-shaped sheet
piles.
If crimped points are used to enhance the shear force transmission in the interlocks of U-shaped sheet
piles, the resistance shall be agreed at the time of enquiry and order, and shall be tested according to the
testing procedure specified in 9.2.5.
If agreed at the time of enquiry and order, the manufacturer can replace the crimping of interlocks by
intermittent welding of interlocks that achieves the same shear force transmission.
EXAMPLE Triple U-shaped sheet piles delivered with one common interlock crimped and one common
interlock partially welded.
See Option 7, Clause 13, (Welding of common interlocks).
7.8.4 Interlock performance criteria
The interlock performance criteria shall comply with the requirements of 9.2.6.
8 Inspection
8.1 Type of inspection and inspection document
The products shall be delivered either with specific or non-specific inspection and testing to indicate
compliance with the order and this document. The manufacturer shall obtain from the purchaser the
information which inspection document according to EN 10204 is required, otherwise a test report 2.2
will be issued.
In the case of specific inspection, testing shall be carried out according to the requirements of 8.3,
Clauses 9 and 10.

NOTE 1 General requirements for the welding of steel sheet pile grades are given in EN 1011-2.
NOTE 2 Steels specified in this document do not have unlimited suitability for the various welding processes,
since the behaviour of a steel during and after welding depends not only on the material, but also on the dimensions
and shape and on the manufacturing and service conditions of the components.
7.2.4 For all steel grades a copper-content between 0,25 % and 0,35 %, or between 0,35 % and 0,50 %
(on mass) on the heat analysis can be agreed upon at the time of enquiry and order. In this case, the
maximum carbon equivalent value of Table 1 shall be increased by 0,02.
See Option 3, Clause 13, (Cu alloyed).
7.3 Mechanical properties
7.3.1 General
Under the inspection and testing conditions as specified in Clauses 8, 9 and 10, the mechanical properties
shall comply with the values given in Table 3.
7.3.2 Impact properties
The impact properties shall be verified by test at the temperature given in Table 3, unless otherwise
agreed upon at the time of the order.
Using test pieces of width less than 10 mm, the minimum values given in Table 3 shall be reduced in direct
proportion to the cross-sectional area of the test piece.
See Option 4, Clause 13, (Verification of impact properties).
7.4 Technological properties
7.4.1 Weldability
General requirements for arc welding of the steels shall be as given in EN 1011-2. In general, steel sheet
pile grades are suitable for arc welding.
NOTE With increasing product thickness and strength level, cold cracking can occur. Cold cracking is caused
by the following factors in combination:
— the amount of diffusible hydrogen in the weld metal;
— a brittle structure of the heat affected zone;
— significant tensile stress concentrations in the welded joint.
7.4.2 Flame straightening
Recommendations regarding flame straightening are laid down in CEN/TR 10347.
7.4.3 Hot-dip zinc-coating
EN ISO 1461 should be used to specify coating requirements. EN ISO 14713-2 provides further guidance,
including information on the influence of various factors, including steel chemical composition, on the
coating formation.
Option 5, Clause 13, can be used to order steels with a chemical composition required for hot-dip zinc
coating. When Option 5 is implemented, the purchaser and manufacturer shall agree to a steel
composition (heat analysis) of silicon and phosphorous according to either:
Category A (see also EN ISO 14713-2:2020, Table 1, Note 1); or

Category B; or
Category D (limited to 0,25 % < Si ≤ 0,35 %)
with required values as cited by the ranges given in EN ISO 14713-2:2020, Table 1, column 2.
NOTE EN ISO 14713-2:2020, Table 1, gives guidance on typical coating characteristics associated with certain
steel compositions on the basis of the surface composition of silicon and phosphorous.
The maximum carbon equivalent shall be increased by 0,02 or by 0,01.
In some cases steels above S 460 may be sensitive to cracking during galvanizing and therefore special
care should be taken.
See Option 5, Clause 13, (Chemical composition for hot dip zinc coating).
7.5 Surface properties
EN 10163-1 and EN 10163-3 shall apply for the permissible surface discontinuities and for the repair of
surface defects by grinding and/or welding. Class C, subclass 1 of EN 10163-3 shall apply, unless
otherwise agreed upon at the time of the order.
The surface requirements and repair conditions of sheet piles shall apply to all surfaces excluding
interlocks and radii at the connection between web and flange.
See Option 6, Clause 13, (Other surface class).
7.6 Internal soundness
The internal soundness shall be in accordance with EN 10021.
7.7 Dimensions, tolerances on dimensions and shape, mass
Dimensions, tolerances on dimensions and shape shall be in accordance with the requirements given in
the standard EN 10248-2.
The nominal mass shall be determined from the nominal dimensions using a volumetric mass of
3
7 850 kg/m .
7.8 Load bearing capacity
7.8.1 General
The design of steel sheet pile structures requires determination of the actions on the structure, for
example the earth pressure, the water pressure, the surface surcharge, etc., and the appropriate
resistances. The actions will give rise to effects all over the structure, for instance internal forces and
moments, stresses, strains and displacements. Additional local effects will also be produced for instance
at points of load applications. The resistances of the sheet piles to the effects of the loads shall be
determined according to the calculation methods defined in EN 1993-5, if applicable. For applicability,
reference can be made to Report EUR 20034 EN (Development of unified design rules for steel sheet piles
for introduction into EN 1993-5). If a calculation method for a specific resistance is not applicable, the
resistance shall be determined by direct testing in accordance with EN 1993-5.
In general, the section resistance can be expressed as the product of the material strength for the chosen
steel grade and a specified geometrical section property dependant on the nominal dimensions of the
section. The rules for calculating the section properties from the nominal dimensions shall be in
accordance with normative Annex B.
