Overview

EN 10264-3:2023 - Steel wire and wire products - Steel wire for ropes - Part 3 - defines requirements for round and shaped non‑alloyed steel wire for high duty applications. Published by CEN (December 2023), this part covers cold‑drawn wires intended for manufacture of ropes used in mine hoisting, man‑riding haulage, passenger cableways and other situations where rope stresses are high or highly variable.

The standard addresses wire forms (round and three shaped profiles: full lock (Z), half lock (H) and trapezoidal (T)), and sets out dimensional, mechanical, chemical and coating requirements specific to high‑duty rope production.

Key topics and requirements

• Scope and profiles: Specifies round wire and shaped wires (Z, H and T) and defines characteristic dimensions (height h, width b, narrowing w, equivalent diameters).
• Tensile strength grades: Defines multiple tensile strength grades for round and shaped wire up to very high levels (new higher grades added, e.g. 2 260 MPa and 2 360 MPa for round Class B; 1 960 MPa added for round Class A). Nominal tensile values are minimum limits; upper limits follow EN 10264‑1 tolerances.
• Dimensional tolerances: Includes detailed diameter tolerances for round wire (ranges from about ±0.015 mm to ±0.070 mm depending on diameter and coating class) and agreed tolerances for shaped wire heights and other critical dimensions.
• Mechanical tests: Specifies required test methods including reverse‑bend endurance criteria (minimum number of reverse bends and mandrel radii for shaped wires) and other mechanical characteristic checks referenced to EN 10218‑1 and EN 10264‑1.
• Chemical composition and coatings: Sets requirements for base steel chemistry (rod sourcing per EN ISO 16120 series) and for coatings - hot‑dip zinc or Zn/Al alloy and electrolytic zinc - including coating class designations and salt‑spray performance guidance (Annex A). Zinc purity and certification requirements reference EN 1179 and EN 10244‑2.
• Manufacture conditions: Wire must be cold drawn from specified rod, free from surface/internal defects that would prejudice rope manufacture.

Applications and users

This standard is essential for:

• Rope and wire‑rope manufacturers specifying wire feedstock for high‑duty ropes
• Mining and hoisting equipment OEMs and maintenance teams
• Cableway and aerial ropeway designers and operators (passenger transport)
• Procurement/specification engineers, test laboratories, and coating suppliers It helps ensure consistent performance, interchangeability and safety of wires used where high or highly variable loads occur.

4 Designation of the product
The designation of wire for ropes manufactured in accordance with this document shall be based on the
nominal dimension, surface appearance and tensile strength.
The indicator of dimension for round wire is the nominal diameter; for shaped wire it is the value of the
height (h), followed by a letter specifying the profile. In the case of H profiles, this indicator shall be
followed by the value of the narrowing.
The surface appearance shall be indicated as defined in EN 10264-1 with U for uncoated or bright wire,
with a letter indicating the Class of coating (A, B, etc.) and in the case of Zn/Al alloy coatings, indicating
in brackets (Zn/Al).
EXAMPLE 1 2,0 mm wire for rope with thick zinc layer, Class A, tensile strength grade 1 570 MPa, in accordance
with EN 10264-3, is designed as follows:
wire for rope EN 10264-3 - 2,0 - A - 1 570
EXAMPLE 2 Wire for rope, trapezoidal profile, h = 3,5 mm, Class B zinc coated, tensile strength grade 1 770 MPa,
in accordance with EN 10264-3, is designed as follows:
wire for rope EN 10264-3 - T3,5 - B - 1 770
EXAMPLE 3 H shaped wire for rope h = 3,0 mm, w = 1,8 mm, coated with Class A Zn/Al alloy, tensile strength
grade 1 370 MPa, in accordance with EN 10264-3, is designed as follows:
wire for rope EN 10264-3 - H - 3,0 × 1,8 - A (Zn/Al) - 1 370
5 General conditions of manufacture
The drawn wire shall be manufactured from rod in accordance with EN ISO 16120-1 and EN ISO 16120-
2 for ropes for static applications, and in accordance with EN ISO 16120-1 and EN ISO 16120-4 for ropes
for dynamic applications.
The drawn wire shall show no surface defects or internal defects prejudicial to its use.
When specified, the drawn wire shall be supplied with a coating applied by a hot dipping or electrolytic
method. The coatings commonly used are zinc or Zn/Al alloy coatings (see Annex A).
Unless otherwise specified, the zinc used for coating shall have a purity of 99,95 % in accordance with
EN 1179, Z3; other zinc alloys may be agreed at the time of enquiry and order.
If required by the purchaser, the quality of the zinc or Zn/Al alloy used for the coating material should be
certified by the manufacturer. Because of the reaction between the base material and coating material,
which is inherent to the process, the composition of the coating on the wire is different to that used in the
coating bath.

6.2 Profiles
6.2.1 Definition of shaped wire
For shaped wire, the characteristic sections of the wire are shown in Figure 1 for full lock Z, half lock H
and trapezoidal T wires.
The nominal dimensions and tolerances shall be agreed between the supplier and the purchaser at the
time of ordering. The conventional characteristic values are as follows:
h height: difference between the radii of the 2 concentric boundary circles;

R radius of the outer boundary circle;
b width: maximum width of upper part perpendicular to a radial line passing through the
centre of the width (as shown in Figure 1);
w minimum narrowing: smallest width of the profile;
e distance taken diagonally across the transverse section of the profile (essentially T or Z
profiles).
The designation of a full lock wire is established using the letter Z and the height (h), that of a half lock
wire by H followed by the height (h) and the minimum narrowing (w) (h × w) and that of a trapezoidal
wire
