Galvanized steel according to DIN EN 10346 is an essential material in many industrial and construction applications. This type of steel is produced through a continuous hot-dip galvanizing process, where a zinc layer is applied to the steel strip. This coating provides excellent corrosion resistance and significantly increases the longevity of the steel products.

Manufacturing Process and Properties
The hot-dip galvanizing process, in which the steel is passed through a bath of molten zinc, results in a uniform zinc coating that protects the steel from rust and other environmental influences. The galvanizing process according to DIN EN 10346 ensures that the coating has high adhesion strength and resistance. The standard specifies requirements for the chemical composition, mechanical properties, and coating thickness of the zinc layer to ensure consistent quality.

Soft steels for cold forming
A significant application of galvanized steel is in the production of soft steels suitable for cold forming. These steels are characterized by their excellent formability and ductility, making them ideal for the production of complex components and body parts in the automotive industry. Soft steels can be easily bent, stamped, and deep-drawn without the risk of cracking or breaking. The galvanized coating provides additional protection against corrosion, which extends the lifespan of the components and reduces maintenance costs. A classification system allows for the selection of the most suitable steel for each specific application:

Steels for construction applications

In addition to the soft steels, there are also hot-dip galvanized steels specifically developed for applications in the construction industry. These steels are characterized by high strength and stability, which are essential for structural applications. They are frequently used in the construction of frameworks, roof and wall cladding, as well as infrastructure. The hot-dip galvanized coating protects the steel components from weathering, chemical attacks, and mechanical damage, which increases the safety and reliability of buildings.

For use in construction, steels are classified according to increasing values of the minimum yield strength (Rp0.2). This classification helps select steels based on their mechanical properties and structural integrity requirements. The minimum yield strength is a crucial parameter that describes the material’s load-bearing capacity under tensile stress. By categorizing steels into different classes, it ensures that the materials used meet the specific requirements and safety standards in construction.

Advantages of Hot-Dip Galvanized Steel
Hot-dip galvanized steel offers numerous advantages that make it a preferred material in many industries. The key benefits include:

Compliance with Standards and Quality Assurance
Adhering to the DIN EN 10346 standard ensures that galvanized steel maintains consistently high quality and performance. This standard includes specific requirements for coating thickness, adhesion strength, and the durability of the zinc layer. Manufacturers producing according to this standard must conduct strict quality controls to ensure their products meet the specified requirements.

Conclusion
Galvanized steel according to DIN EN 10346 is a versatile and high-performance material used in numerous industrial and construction applications. Whether for the production of soft steels for cold forming or high-strength construction steels, the galvanized coating provides excellent corrosion protection and contributes to the durability and cost-effectiveness of the products. Adherence to strict standards and quality regulations ensures consistently high quality that meets the diverse demands of modern applications.
