General Information
Overview
prEN 10249-2: Cold Formed Steel Sheet Piling - Tolerances on Shape and Dimensions is a European draft standard developed by CEN's Technical Committee ECISS/TC 10, focusing on specifying the allowable tolerances for cold-formed, non-alloy steel sheet piles. These tolerances cover critical geometric and physical characteristics such as dimensions, squareness of ends, straightness, and mass. Precise control of these parameters is essential for ensuring structural reliability and interchangeability in civil engineering and construction projects involving steel sheet piling.
This standard complements prEN 10249-1, which defines technical delivery conditions for these steel profiles. prEN 10249-2 updates the superseded EN 10249-2:1995 and provides detailed guidance on acceptable deviations to maintain quality and functional performance of steel sheet piling in construction.
Key Topics
Height and Width Tolerances
Height tolerances vary with profile size, ranging from ±4 mm for heights ≤ 200 mm up to ±10 mm for heights over 400 mm. Width tolerances allow for +2% variation on individual piles and +3% on interlocked pairs, ensuring dimensional consistency for fitting and load transfer.Wall Thickness
Thickness deviations must comply with EN 10051 standards, guaranteeing material strength and durability across all profile sections.Straightness (Bending, Curving, Twisting)
Straightness is controlled through limitations on bow-heights in both horizontal (bending) and vertical (curving) planes, each restricted to less than 0.25% of profile length. Twisting is limited to 2% of length, max 100 mm, preventing assembly issues and structural weaknesses.Length and Squareness of Ends
Standard length tolerance is +50 mm, with the option for tighter control. Squareness deviation cannot exceed 2% of profile width, vital for modular assembly where precise end alignment is crucial.Angular Deviation on Flanges
Flange angle tolerance ranges from +2° to +3°, depending on leg size, ensuring compatibility with connecting elements in the piling system.Mass Tolerance
Mass deviation must not exceed +7% relative to calculated mass, supporting consistency in structural calculations and transport logistics.Joints and Overlapping
Manufacturers may choose joint designs, but interlocks must provide adequate free play for easy fitting, verified with sample tests to guarantee installation efficiency.
Applications
- Civil Engineering: Used in foundation support, retaining walls, and flood defense structures requiring reliable and dimensionally precise steel sheet piling.
- Marine Construction: Essential for quay walls, cofferdams, and other water-related structures where tolerance control assures watertight and stable assembly.
- Infrastructure Projects: Enables consistent use of interlocking sheet piles in bridges, highways, and urban development foundations.
- Manufacturing of Steel Profiles: Serves as a quality benchmark for steel producers and fabricators specializing in cold-formed sheet piling.
By adhering to standardized tolerances, manufacturers and engineers ensure the interoperability, safety, and performance of cold-formed steel sheet piling systems across European markets.
