Galvanized steel
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.
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.

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.
