5 Materials
5.1 Hot dip galvanizing bath
The chemical composition of the contents of the hot dip galvanizing bath shall comply with (the relevant
clauses in) EN ISO 1461.
5.2 Repair material
Material for repairing damaged coating and renovating uncoated areas shall be an appropriate zinc-rich
formulation (paint).
6 Designation
The designation of the products shall be in accordance with EN 10080, except the reference to EN 10080.
In addition, the designation shall include the following:
a) A reference to this European Standard.
b) The additional symbol +Z (hot-dip zinc coating) added to the technical class(es) of steel(s) and the coating
class (see Table 2).
7 Information to be supplied at the time of enquiry and order
The following information shall be supplied at the time of enquiry and order:
 quantity ordered;
 the designation of the product in accordance with Clause 6;
 the packaging and protection requirements;
prEN 10348:2006 (E)
 surface treatment if required (see Clause 8);
 the requirements for documentary information to accompany the delivery (e.g. delivery note, type and
content of inspection document according to EN 10204);
 special requirements for labelling.
8 Manufacture (galvanizing)
It is at the discretion of the manufacturer to choose the galvanization method, unless otherwise agreed.
Zinc coating processes can be subdivided in two main categories:
1. zinc coating applied before further working operations (e.g. cutting, welding, bending, etc);
2. zinc coating applied to the final reinforcing steel products not subject to bending.
Any further surface treatment of the galvanized coating and its method of application may be specified (e.g.
passivation, etc.).
NOTE The manufacturer should exercise due care:
 to avoid distortion or cracking of the steel reinforcement occurring during galvanizing; and
 of steel reinforcement that is susceptible to embrittlement in processing.
9 Performance characteristics
9.1 Chemical composition
For the chemical composition EN 10080 shall apply.
9.2 Mechanical properties
The mechanical properties of galvanized reinforcing steels shall be those of the technical class agreed at the
time of enquiry and order (see EN 10080 and the non conflicting product specification defining the technical
class).
No retesting of mechanical properties is required for products on which the zinc coating is applied at a
