7.5 Technological properties
7.5.1 Weldability
7.5.1.1 General requirements for the welding of steel sheet pile grades are given in EN 1011-2.
7.5.1.2 Steels specified in this European Standard 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.
7.5.2 Durability
7.5.2.1 General
Durability is dependent on the chemical composition of the steel.
NOTE
Steels specified in this European Standard can be used in general, structural and civil
engineering works without any specific corrosion protection. In this case, the durability of the
sheet-piling wall can be ensured by a sacrificial thickness for corrosion allowance. The
corrosion rates to be accounted for in order to calculate the sacrificial thickness depend on
the environment where sheet-piling are exposed and on the service life of the sheet-piling
structure. The sacrificial thickness for corrosion allowance can be determined according to
the corrosion rates defined in Eurocode EN 1993-5. The durability of steel sheet-piling can
also be enhanced by suitable corrosion protections like organic coatings, metallic coatings, or
cathodic protection.
7.5.2.2 Suitability for hot-dip zinc coating
Where specified at the time of the enquiry and order, the suitability and the relevant product quality
requirements for hot dip zinc coating may be agreed.
Option 6 : see 10.7
7.6 Load Bearing Capacity
7.6.1 General
The design of steel sheet-piling structures requires on one hand determination of the actions on the structure,
for example the earth pressure, the water pressure, the surface surcharge, etc, and on the other hand
determination of 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-piling to the effects of
the loads shall be determined according to the calculation methods defined in Eurocode EN 1993-5.
In general, the section resistance can be expressed as the product of the material strength, depending on
the steel grade, by a specified geometrical section property, depending on the nominal dimensions of the
section. The rules for calculating the section properties from the sheet-piling nominal dimensions are given in
the normative Annex C.
7.6.2 Interlock Resistance of Straight Web Sheet-piles
Where a manufacturer wishes to declare interlock resistance of straight web piles, the resistance shall be
tested according to the normative Annex D.
The interlock resistance of straight web sheet-piles is verified only when specified at the time of order.
Option 7 : see 10.8
7.6.3 Resistance of Crimped Points of U-piles
Crimped points can be used to enhance the shear force transmission in the interlocks of U-piles.
Where a manufacturer wishes to declare the resistance of crimped points, the resistance shall be tested
according to the normative Annex E.
The interlock resistance of crimped points of U-piles is verified only when specified at the time of order.
Option 8 : see 10.9
7.7 Tolerances on dimensions and shape
The tolerances on dimensions and shape defined in EN 10248-2 shall apply. The manufacturer shall declare
the dimensional form of the sheet-piles.
7.8 Minimum interference on interlocking
The types of interlocks of the sheet-piles and their minimum interlocking interference shall comply with Table
15 of prEN 10248-2:2005.
7.9 Surface Condition
7.9.1 General Requirement
The surface requirements and repair conditions of sheet piling apply to all surfaces excluding interlocks and
radii at the connection between web and flange.
7.9.2 Surface imperfections
Sheet piling may have surface imperfections. Surface imperfections are surface discontinuities that are
considered as being inherent to the manufacturing process and are permissible irrespective of their number,
provided the limits of Table 3 are not exceeded.
7.9.3 Surface defects
Surface discontinuities with a depth exceeding the limits of Table 3 are considered as defects and must be
repaired irrespective of their number. Repair by grinding and/or welding is permitted, provided that :
a) after the elimination of the defect and before welding the thickness shall not be less than 80 % of
the nominal thickness,
b) the sum of the areas repaired by welding, with the exclusion of interlocks and radii at connection
between web and flange, shall not be more than 15 % of the surface area of the sheet pile under
inspection,
c) the reinforcement of the groove weld shall be ground flush with the surface of the sheet pile,
d) the dimensional tolerances specified in EN 10248-2 shall be complied with after repair.

(Normative)
Calculation of Geometrical Cross-sectional Properties
Geometrical cross-sectional properties, as second moment of area I, section modulus W, etc… shall be
calculated from nominal geometrical values of the section that are specified in the product specifications.
NOTE In general, such nominal values should be such that the section properties calculated represent the expected
values of the statistical distribution of properties determined from the annual production. Thereby, the production is
assumed to comply with the standards for geometrical tolerances.
The reference axis for the section properties should be specified together with the section properties.
For the calculation of the geometrical section properties, reference should be made to the mathematical
definition of these properties. If simplified calculation methods are used, care shall be taken that safe sided
results are obtained.

Interlock strength of straight web steel sheet piles
D.1 General
(1) In the following, provisions are given for determining the characteristic interlock resistance R of straight
k,s
web steel sheet piles by testing.
(2) The characteristic interlock resistance shall be related to a specific nominal interlock geometry and, if
required, to a specific steel grade in accordance with (3).
(3) If variation of the steel grade has a substantial influence (more than 10 %) on the test result, it shall be
taken into account when evaluating the tests and the results shall then be given in relation to the steel grade.
(4) The determination of the mechanical properties of the steel used for the specimen in these tests shall be
carried out according to 7.4.
D.2 Test specimen
(1) The test specimen shall be cut from the pile perpendicular to the rolling direction as shown in figure D.1.
(2) The width w of the specimen shall be ≤ 100mm.

Determination of strength properties of crimped points for U-piles
E.1 General
(1) In the following, provisions are given for the determination of strength properties of crimped points by
testing, in order to improve the transmission of shear forces in the interlocks of U-piles according to
EN1993-5.
(2) Two items shall be addressed in the tests:
� determination of the characteristic ultimate resistance R of one crimped point;
k
� verification that the minimum stiffness criterion for the crimped point is fulfilled.
(3) These two items shall be determined for the representative interlock geometry of the pile. If variation of
the steel grade has a substantial influence (more than 10 %) on the test result, it shall be taken into
account when evaluating the tests and the results shall then be given in relation to the steel grade. The
data on the crimped points to be used for design shall be obtained from tests for the relevant crimped
point layout (single, double or triple points).
NOTE 1 If different piles are provided with the same nominal interlock geometry, the results obtained may be applied to
all these piles.
NOTE 2 The results obtained using this procedure for a representative interlock geometry cover also the manufacturing
tolerances of the interlocks and they can be extended to the sheet pile range with the same nominal geometry.
(4) The determination of the mechanical properties of the steel used for the specimen in these tests shall be
carried out according to 7.4.
(5) The determination of the characteristic ultimate resistance R and the verification of the stiffness criterion
k
shall be carried out by compression tests using test specimen in accordance with E.2 (2) and (3).
E.2 Test specimen
(1) For the manufacturing of the test specimen the following aspects shall be taken into account:
- the specimen (sheet piles) shall be tested as rolled;
- the specimen shall be cut out of a crimped double pile.
(2) The layout of the test specimen used for compression tests shall be in accordance with figure E.1 for
single, double or triple crimped points.
(3) The following aspects should be taken into account in order to avoid excessive eccentricities:
- the distance between the upper and lower plates as shown in figure E.1 should not vary more than 0,5
mm;
- the deviation of the perpendicularity between the test specimen and the plate should not exceed 2 % in
each of two mutually perpendicular directions (measured as 1% of b, see figure E.2);
- the tolerance on squareness of specimen ends should be less than 1,0 mm, see clause 9 of prEN
10248-2:2005;
- the specimen should be placed in the centre of the plates.

E.3 Testing and evaluation
(1) The tests shall be carried out as a displacement controlled test with a maximum deflection rate of 20
mm/min.
(2) In order to be able to determine the two items given in E.1 (2) the load applied by the testing machine
and the displacement of the cross-head shall be measured continuously, to obtain the load-
displacement curve for the specimen.
(3) The measured value R for one specimen is the maximum force measured in the test for a
ult,i
displacement ≤ 5 mm, divided by the number of crimped points, see figure E.3.
(4) It shall be verified in the load-displacement curve that the minimum stiffness in accordance with
EN1993-5 has been reached. If several tests have been carried out, this verification may also be
carried out based on statistical evaluation in accordance with annex D of EN 1990:2003.
NOTE The verification for one specimen may be carried out according to the following procedure, see figure E.3:
- linearisation of the curve (A)
- drawing the line corresponding to the required minimum stiffness (B)
- the verification is fulfilled if the linearised curve is on the left hand or on the minimum
stiffness line.
