Zudem bietet die Norm umfassende Hinweise zur Reinigung und Vorbehandlung von feuerverzinkten oder sherardisierten Stahlprodukten, was die Qualität der Endprodukte weiter verbessert. Die Norm berücksichtigt ebenfalls die speziellen Anforderungen und Unterschiede zu anderen Beschichtungsverfahren, indem sie klarstellt, dass sie nicht für Artikel mit Zink-Aluminium- oder Aluminium-Zink-Beschichtungen gilt. Dies trägt zur Klarheit und zu einer präzisen Anwendung der Standards in der Praxis bei, was für Hersteller und Anwender gleichermaßen von Vorteil ist. Insgesamt ist die EN 13438:2013 ein unverzichtbares Dokument für die Industrie, da es sowohl die Qualität der Oberflächenbehandlung als auch die Langlebigkeit der beschichteten Produkte sicherstellt. Die Norm leistet einen bedeutenden Beitrag zur Verbesserung der Sicherheits- und Leistungsstandards im Bauwesen, und ihre Relevanz wird durch die klaren, praxisorientierten Anforderungen weiter gestärkt.

The EN 13438:2013 standard provides a comprehensive framework for evaluating powder organic coatings applied to hot dip galvanised or sherardised steel products intended for construction purposes. Its scope is clearly delineated, focusing on the performance requirements specific to organic coating powders when applied to finished articles, such as batch hot dip galvanised components and continuously hot dip galvanised sheets. One of the strengths of this standard is its specificity; it targets a niche area within the broader context of coatings for steel products, ensuring that users can rely on the defined performance criteria that are crucial for maintaining the integrity and longevity of construction materials. The standard also offers valuable guidance on the essential cleaning and pretreatment processes required prior to powder coating, which helps to ensure optimal adhesion and durability of the coatings. Furthermore, EN 13438:2013 distinguishes itself by clearly outlining the limitations of its applicability, specifying that it does not pertain to articles with zinc-aluminium or aluminium-zinc coatings, or to hot dip galvanised wire.
