Paints and varnishes - Powder organic coatings for galvanized or sherardised steel products for construction purposes
This European Standard specifies performance requirements for powder coatings applied to galvanized or sherardised steel products, for architectural (internal and external application), fencing and construction purposes. Galvanized steel products can be articles batch hot dip galvanized (galvanized after fabrication) or articles consisting of continuous hot dip galvanized sheet which is then subsequently fabricated. This standard does not apply to articles with zinc-aluminium coatings (EN 10214) or aluminium-zinc coatings (EN 10215), or to continuously hot dip galvanized wire. Requirements for cleaning and pre-treatment of the galvanized or sherardised steel products prior to powder coating are also specified.
Beschichtungsstoffe - Pulverbeschichtungen für verzinkte oder sherardisierte Stahlerzeugnisse für Bauzwecke
Diese Europäische Norm legt Leistungsanforderungen an Pulverbeschichtungen fest, die auf feuerverzinkte Stahlerzeugnisse aufgetragen wurden und für Zwecke der Architektur (Innen- und Außenanwendung), für Umzäunungen sowie für Bauzwecke allgemein vorgesehen sind. Feuerverzinkte Stahlerzeugnisse können Gegenstände sein, die stückverzinkt (nach der Herstellung feuerverzinkt) wurden oder aus kontinuierlich feuerverzinktem Band oder Blech bestehen, welches anschließend verarbeitet wurde. Diese Norm gilt nicht für Gegenstände mit Zink-Aluminium-Überzügen oder Aluminium-Zink-Überzügen sowie für kontinuierlich feuerverzinkten Draht. Anforderungen an die Reinigung und Vorbehandlung der Stahlerzeugnisse vor dem Pulverbeschichten werden ebenfalls festgelegt.
Peintures et vernis - Revêtements de poudre organique pour produits en acier galvanisé ou shérardisé utilisés dans la construction
La présente Norme européenne spécifie les exigences de performance des revêtements de poudre appliqués
sur des produits en acier galvanisé ou shérardisé utilisés dans l'architecture (application en intérieur et en
extérieur), le clôturage et la construction. Les produits en acier galvanisé peuvent être des articles galvanisés
à chaud en bain (après fabrication) ou des tôles d'acier galvanisé à chaud en continu, qui passent ensuite en
fabrication. La présente norme ne s'applique pas aux articles revêtus de zinc-aluminium ou d'aluminium-zinc,
ni au fil d'acier galvanisé à chaud en continu. Elle précise également les exigences relatives au nettoyage et
au prétraitement des produits en acier galvanisé ou shérardisé avant l'application du revêtement de poudre.

Foreword
This European Standard (EN 13438:2005) has been prepared by Technical Committee CEN/TC 139 “Paints
and varnishes”, the secretariat of which is held by DIN.
This European Standard shall be given the status of a national standard, either by publication of an identical
text or by endorsement, at the latest by May 2006, and conflicting national standards shall be withdrawn at the
latest by May 2006.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic,
Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania,
Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, Switzerland
and United Kingdom.
Introduction
This European Standard has been produced as a result of the growing demand for products made of powder
coated hot-dip galvanized or sherardised steel. These products offer a combination of corrosion resistance
and decorative appearance.
It is assumed in the drafting of this standard that the specified test methods will be applied by those who are
suitably trained and supervised.
This European Standard has been written from a coating performance perspective and does not seek to set
out one method of powder coating galvanized or sherardised steel products. In order to facilitate production of
the best quality powder coated hot dip galvanized or sherardised articles however, experience has shown that
it is important that sufficient dialogue between the client, specifier, designer, fabricator, galvanizer or
sherardiser and powder coating applicator takes place at the earliest stages of the project and that where
possible timescales set out for processing of the work are practical and adhered to. A guidance document
dealing with these and other aspects of supply is currently under development.
1 Scope
This European Standard specifies performance requirements for powder coatings applied to galvanized or
sherardised steel products, for architectural (internal and external application), fencing and construction
purposes. Galvanized steel products can be articles batch hot dip galvanized (galvanized after fabrication) or
articles consisting of continuously hot-dip galvanized sheet which is then subsequently fabricated. This
standard does not apply to articles with zinc-aluminium coatings or aluminium-zinc coatings, or to continuously
hot dip galvanized wire. Requirements for cleaning and pre-treatment of the galvanized or sherardised steel
products prior to powder coating are also specified.

4 Substrate material
The substrate shall be hot dip galvanized steel in accordance with EN ISO 1461, EN 10326, EN 10327 or
sherardised steel in accordance with EN 13811. If required, steel sections shall be free from surface

NOTE 1 The galvanizer or the sherardiser and coating applicator should be consulted about the design of the steel
products intended for galvanizing or sherardising after construction, prior to the fabrication stage, in order to optimise
galvanizing and powder coating quality. EN ISO 12944-4 provides some guidance on surface conditions that might be
encountered on post fabrication hot dip galvanized or sherardised articles.
NOTE 2 To achieve optimum quality of finished product sharp edges on the fabrication should be avoided.
