Overview

EN 10059:2003 is a CEN European standard that defines the nominal dimensions and the tolerances on shape and dimensions for hot‑rolled finished square steel bars for general purposes. It sets the dimensional framework that manufacturers, purchasers and inspectors use to ensure compatibility, interchangeability and acceptable geometric quality of square steel bars used across general engineering and fabrication applications. (ICS: 77.140.60)

Key topics and requirements

The standard focuses on measurable, verifiable aspects of hot‑rolled square bars rather than chemical composition or mechanical properties. Main technical topics include:

• Nominal dimensions: designation of standard square side sizes for hot‑rolled finished bars.
• Dimensional tolerances: permissible deviations from nominal side dimensions to ensure fit and function.
• Shape tolerances: allowable departures from ideal square geometry (for example, crooking, bending, and variation between sides).
• Length tolerances: permitted variations in supplied bar lengths or cut lengths where applicable.
• Surface and finish considerations: requirements for finished surface condition insofar as it affects dimensional assessment.
• Inspection and verification: criteria and references for checking dimensions and shape during quality control.

Note: EN 10059:2003 describes scope and measurement-related requirements; it does not redefine material grades or mechanical test methods for steel itself.

Practical applications

EN 10059:2003 is relevant wherever hot‑rolled square steel bars are used and dimensional conformity matters:

• Structural and general engineering components where square sections are incorporated.
• Machining and fabrication shops that require predictable stock dimensions for planning and tolerancing.
• Manufacture of fasteners, shafts, tooling blanks or fabricated assemblies that start from square bar stock.
• Supply chain and procurement to specify and verify delivered product against agreed tolerances.

Using bars conforming to EN 10059 reduces rework, improves interchangeability, and supports consistent quality across suppliers.

Who should use this standard

• Steel producers and rolling mills (to define and certify supplied dimensions).
• Quality assurance and inspection teams (to verify dimensional compliance).
• Design and procurement engineers (to specify acceptable tolerances in procurement documents).
• Fabricators and machinists (to plan allowances and machining operations).

Related standards

For comprehensive specifications, EN 10059 is typically used alongside other European and international standards covering steel grades, mechanical testing, surface quality and product marking. Users should cross‑reference relevant CEN/ISO standards for material properties and testing methods when specifying a complete product requirement.
