Overview

oSIST prEN 10248-2:2006 is a key European standard developed by CEN that specifies the tolerances on shape and dimensions for hot rolled, non-alloy steel sheet piling. This document is part two of the standard series on hot rolled steel sheet piling (the first part being EN 10248-1, which defines the technical delivery conditions). The standard provides clear guidelines on acceptable deviations in dimensions, squareness of ends, straightness, and mass for various types of steel sheet piles including U-sheet, Z-sheet, straight-web, and H-sheet piles.

Ensuring compliance with these tolerances is critical for manufacturers, suppliers, and contractors involved in civil engineering and construction projects where steel sheet piling is used. This standard helps guarantee that the products meet quality requirements, fit correctly on site, and perform reliably under structural loads.

Key Topics

• Height Tolerances
  Defines permissible variations in height for different sheet pile profiles:

  • U-sheet piles: ±4 to ±5 mm depending on nominal height
  • Z-sheet piles: ±5 to ±7 mm depending on nominal height
  • H-sheet piles: ±5 to ±7 mm depending on nominal height

• Width Tolerances
  Width deviations are expressed as a percentage of nominal width, with typical values:

  • Single piles: ±2%
  • Double (interlocked) piles: ±3%
    This ensures accurate fit and interlocking on site.

• Wall Thickness Tolerances
  Thickness tolerances depend on nominal thickness:

  • For thickness ≤ 8.5 mm: typically -0.5 mm (negative tolerance) with positive tolerance at manufacturer discretion
  • For thickness > 8.5 mm: tolerance of -6% with positive tolerance options
    These criteria apply to all profile types.

• Straightness and Length
  Straightness deviation should be less than 0.2% of the pile length, ensuring installation ease and structural integrity.
  Length tolerances are ±200 mm but may be reduced by agreement.

• Squareness of Ends
  The cut ends' squareness tolerance limits deviation to 2% of the width for U-, Z-, and straight-web piles, and 4% of the height for H-piles.

• Mass Tolerance
  Delivered mass may vary up to +5% from the calculated mass based on ordered dimensions, providing consistency in material quantity and quality.

• Interlock Specifications
  Interlocks must have sufficient free play (minimum interference of 4 to 6 mm depending on type) to facilitate assembly and load transfer.

• Options Available
  Customers can agree on tailored tolerance options during enquiry and ordering, including reduced tolerances or positive thickness deviations.

Applications

The tolerances defined in oSIST prEN 10248-2:2006 are essential for various civil engineering and construction applications, specifically:

• Marine construction - quays, breakwaters, and seawalls where precise piling dimensions ensure watertight and stable structures.
• Foundation engineering - retaining walls and excavation supports, where tolerance influences load distribution and safety.
• Infrastructure projects - bridges, roads, and railways requiring durable and dimensionally accurate sheet piling for long-term performance.
• Urban development - building basements and substructures benefiting from reliable sheet piling conforming to defined tolerances.

By adhering to these tolerances, manufacturers can ensure that steel sheet piling components fit perfectly, maintain structural integrity, and reduce installation delays or failures.

Related Standards

• EN 10248-1: Hot rolled steel sheet piling - Part 1: Technical delivery conditions - defines the material grades and properties that complement the tolerances in part 2.
• EN 10025 series: Structural steels specifications often referenced for base material quality in steel piling procurement.
• ISO 9001: Quality management standards ensuring consistent manufacturing quality aligned with tolerance requirements.
• EN 1993 (Eurocode 3): Design of steel structures which references material tolerances for calculation and safety verification.

Adopting oSIST prEN 10248-2:2006 supports industry best practices by setting stringent, yet practical dimensional tolerances on hot rolled steel sheet piling. This facilitates international trade, quality assurance, and optimal structural performance in steel sheet pile construction projects.

3 General Requirement
The determination of sheet-piling dimensions and tolerances must comply with the following
preparation before any measurement is carried out. This requirement applies in the workshop or on-
site without any distinction.
The sheet piling to be measured must be extracted from the storing stack and must be laid down on
the ground separately. The reference ground must be flat and free of any local relief over the length of
the sheet piling. Transverse supports, e.g. blocks, may be used for supporting the sheet piling on the
ground, but the distance between supports must not exceed five meters. The sheet piling must be laid
down with the lower flange on the ground parallel to it : in particular, double U-piles and single Z-piles
must be supported by blocks or any suitable supporting device.
