Steel Specifications: Introduction
As part of the exercise towards the removal of technical barriers to trade, the European
Committee for Iron & Steel Standardisation (ECISS) has prepared a series of European
Standards (ENs) for structural steels.
EN 10025 : 2004 is the new European standard for structural steel. The following
pages show the new grades, properties and the nearest equivalent grades from former
standards including EN 10025 : 1993. The grade designation system is also explained.
Dent Steel can provide a very wide range of rolled sections and plates and the
information following has been prepared to show how the new standard applies to
these products.
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 reissued 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and at the same time BS 4360 was officially withdrawn.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In 1996, with the publication of EN 10137, BS 7613 was withdrawn.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.
