Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www .iso .org/patents).

INTERNATIONAL STANDARD ISO 16172:2018(E)
Steel sheet, metallic-coated by the continuous hot-dip
process for corrugated steel pipe
1 Scope
This document is applicable to the minimum requirements for steel sheet used in the manufacture
of corrugated steel pipe, in coils, flat cut lengths and corrugated cut lengths metallic-coated by the
continuous hot-dip process.
This product is intended for storm sewers, culverts, drains and similar uses.
Several metallic-coated materials are covered, which relies on users to determine which product best
serves their needs. Four different metallic coatings are included:
— zinc coated;
— zinc-5 % aluminium-mischmetal alloy coated;
— 55 % aluminium-zinc alloy coated;
— aluminium-silicon alloy coated.
