Introduction
EN 10025 : 2004 is the new European standard for
structural steel.
EN 10025 : 2004 is the new European standard for
structural steel. This leaflet shows the new grades,
properties and the nearest equivalent grades from
former standards including EN 10025 : 1993. The grade
designation system is also explained.
Corus produces a very wide range of rolled sections and
plates and the information below has been prepared to
show how the new standard applies to these products.
For information on the size ranges available please ring
+44 (0) 1724 404400 and ask for ‘Plate products range
of sizes’ for plate and plate cut from coil, or ‘Structural
sections to BS4 part 1’ for rolled sections.
History of the standard
The European Committee for Iron and Steel
Standardisation is responsible for producing the
European Standards (ENs) for structural steels. The first
of these standards, EN 10025, was published in the UK
by BSI as EN 10025 : 1990, partly superseding
BS 4360 : 1986, which was re-issued as BS 4360 : 1990.
In 1993, a second edition of EN 10025 was made
available together with EN 10113 : parts 1, 2 & 3 and EN
10155. In June 1994, EN 10210 : part 1 was published
and at the same time BS 4360 was officially withdrawn.
The balance of the BS 4360 steels not affected by these
ENs were re-issued in new British Standards BS 7613
and BS 7668. In 1996, with the publication of EN 10137,
BS 7613 was withdrawn. BS 7668 will remain until an
EN for atmospheric corrosion resistant hollow sections
is available.
In 2004 the standard EN 10025 was revised to address the
provisions of EU Construction Products Directive
(89/106/EEC). It is now published in six parts to bring
together almost all the ‘Structural Metallic Products’ into
one comprehensive standard.

The new standard EN 10025 : 2004
The new standard is published in six parts and draws
together earlier standards to produce one standard for
the majority of structural steel products. The parts are:
•Part 1 - General technical delivery conditions.
•Part 2 - Technical delivery conditions for non-alloy
structural steels.
Supersedes EN 10025 : 1993
•Part 3 - Technical delivery conditions for normalised/
normalised rolled weldable fine grain structural steels.
Supersedes EN 10113 : parts 1 & 2 : 1993
•Part 4 - Technical delivery conditions for
thermomechanically rolled weldable fine grain
structural steels.
Supersedes EN 10113 : parts 1 & 3 : 1993
•Part 5 - Technical delivery conditions for structural
steels with improved atmospheric corrosion
resistance - also known as weathering steels.
Supersedes EN 10155 : 1993
•Part 6 - Technical delivery conditions for flat products
of high yield strength structural steels in the quenched
and tempered condition.
Supersedes EN 10137 : parts 1 & 2 : 1996
