La norme EN 10326:2004, intitulée "Produits en bandes et feuilles d'aciers structuraux revêtus par immersion à chaud - Conditions techniques de livraison", apporte des spécifications claires et précises concernant les produits en acier structuraux continuellement revêtus à chaud de zinc, d'alliages de zinc-fer, de zinc-aluminium, d'aluminium-zinc et d'aluminium-silicium. Son domaine d'application s'étend aux bandes de toutes largeurs et aux feuilles découpées, ce qui en fait un document essentiel pour l'industrie de la fabrication métallique. Une des forces majeures de cette norme réside dans son attention portée aux conditions de livraison techniques. En réglementant des épaisseurs de revêtement allant de 0,35 mm à 3,0 mm, tout en offrant la possibilité d'adapter ces spécifications pour des produits de plus de 3,0 mm sur demande, elle démontre sa flexibilité pour répondre aux besoins variés des utilisateurs. Ce niveau de détail dans les exigences techniques est particulièrement pertinent dans les applications où la résistance minimale à la traction et la résistance à la corrosion sont primordiales, deux critères essentiels dans le choix des matériaux pour des constructions durables. De plus, la norme souligne que la résistance à la corrosion est proportionnelle à l'épaisseur du revêtement, ce qui constitue une information cruciale pour les concepteurs et les ingénieurs. Cela permet d'optimiser le choix des matériaux en fonction des environnements d'utilisation, assurant ainsi leur longévité et leur fiabilité. Il est important de noter que la norme exclut certains types de produits, ce qui renforce sa clarté et sa pertinence dans le domaine ciblé. En précisant que les produits en acier faiblement carburé et les produits électro-galvanisés ne sont pas couverts, la norme évite toute confusion pour les utilisateurs potentiels et garantit une application rigoureuse des critères de qualité indiqués. En somme, la norme EN 10326:2004 s'impose comme un document fondamental pour les acteurs du marché des aciers structuraux revêtus, en apportant des lignes directrices précises et adaptées aux défis contemporains de l'industrie.

SIST EN 10326:2004は、構造用鋼で製造された連続的に熱浸 galvanized コーティングのストリップおよびシートに関する技術的な納品条件を規定する欧州標準です。この標準は、亜鉛（Z）、亜鉛-鉄合金（ZF）、亜鉛-アルミニウム合金（ZA）、アルミニウム-亜鉛合金（AZ）、およびアルミニウム-シリコン合金（AS）でコーティングされた製品に対して適用される要件を明確に示しています。具体的には、厚さ0.35 mmから3.0 mmの範囲で、幅に関しては全てのストリップおよび600 mm未満のカットシートに適用可能です。 この標準の強みは、主に最小降伏強度と耐腐食性が重要な要素である用途に向けて設計されている点にあります。コーティングの厚さは、この合金の耐腐食性に比例し、その質量にも影響を与えます。加えて、顧客が問い合わせ時および注文時に合意すれば、厚さが3.0 mmを超える製品にも適用可能であり、その場合は機械的特性、コーティングの密着性、表面状態の要件も事前に合意する必要があります。 さらに、標準は低炭素鋼のストリップ及びシートに対しては適用されず、電解亜鉛メッキされた冷間圧延鋼や連続有機コーティング施されたフラット鋼製品の規格も含まれていません。これにより、特定の用途に対する適切な基準を確立し、必要な品質を保つことができます。 このように、SIST EN 10326:2004は、構造用鋼の連続熱浸コーティング製品に関する厳格な要件を規定しており、その応用範囲、強み、関連性において、業界内での重要な基準となっています。
Die EN 10326:2004 beschreibt umfassend die technischen Lieferbedingungen für kontinuierlich feuerverzinkte Produkte aus Baustählen. Diese europäische Norm ist besonders relevant für die Metallindustrie, da sie präzise Anforderungen an Produkte stellt, die mit verschiedenen Zinklegierungen beschichtet sind, einschließlich Zink (Z), Zink-Eisen-Legierung (ZF), Zink-Aluminium-Legierung (ZA), Aluminium-Zink-Legierung (AZ) und Aluminium-Silizium-Legierung (AS). Der Anwendungsbereich umfasst sowohl Streifen als auch Platten, die nach Kundenwunsch in unterschiedlichen Breiten und Längen gefertigt werden können, wobei die Dicke der Produkte zwischen 0,35 mm und 3,0 mm variieren kann. Ein bemerkenswerter Vorteil dieser Norm liegt in ihrer Flexibilität. Bei Vereinbarung kann sie auch auf plattierte Flachprodukte mit einer Dicke von mehr als 3,0 mm angewendet werden, was eine Anpassung an spezifische Kundenbedürfnisse ermöglicht. Die Norm hebt die Bedeutung der mechanischen Eigenschaften und der Haftung der Beschichtung hervor, welche ebenfalls individuell beim Auftrag festgelegt werden können. Ein wesentlicher Grund für die Anwendung dieser Norm ist die Gewährleistung einer minimalen Streckgrenze und einer hohen Korrosionsbeständigkeit, die in vielen industriellen Anwendungen kritisch ist. Die Norm dokumentiert, dass die Korrosionsbeständigkeit direkt mit der Dicke der Beschichtung korreliert, was für Designer und Ingenieure von Bedeutung ist, die die Lebensdauer und Zuverlässigkeit ihrer Produkte optimieren möchten. Die EN 10326:2004 schließt jedoch spezifische Produktgruppen aus, darunter kontinuierlich feuerverzinkte Produkte aus niedriglegiertem Stahl für die Kaltumformung sowie elektrolytisch verzinkte Flachprodukte. Dies stellt sicher, dass die Norm klar und fokussiert bleibt, ohne Verwirrung durch nicht relevante Produkte herbeizuführen. Insgesamt bietet die EN 10326:2004 eine solide Grundlage für die Herstellung und Lieferung von hochbelastbaren, korrosionsbeständigen Stahlprodukten, die in verschiedenen Anwendungen eingesetzt werden, und bestätigt somit ihre große Relevanz im Bereich der Baustähle.
