1 Scope
This document specifies round and shaped non alloyed steel wire for use in the manufacture of ropes for
mine hoisting, man-riding haulage, cableways for the transportation of passengers and other high duty
applications. Heavy duty refers to situations where the stresses applied to the rope are either high or vary
by a large amount during service.
This document refers to round wires and three types of shaped wire: full lock (Z), half lock (H) and
trapezoidal (T).
It does not apply to steel wire taken from manufactured ropes.
This document specifies the following for cold drawn non alloyed steel wire for ropes for high duty
applications:
— dimensional tolerances;
— mechanical characteristics;
— requirements relating to the chemical composition of the steel wire;
— conditions to be satisfied by any coating.

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 Characteristics of the wire
6.1 Tensile strength grades
The tensile strength grades are specified in Table 1.

NOTE 1 The nominal values are the minimum tensile strength limits. The upper limits (maxima) are equal to
these minimum values increased with the tolerances specified in EN 10264-1.
NOTE 2 Coated means zinc or Zn/Al alloy coating.
NOTE 3 Subject to agreement between the manufacturer and the purchaser, other tensile strength grades can
be used.

Mass of coatings for static and dynamic applications are specified in Table 11.
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 by the letter T followed by the height (h).
