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.

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.
