Hot-dip galvanized steel S390GD in accordance with the EN 10346 standard is a high-strength structural steel that has been specially developed for demanding applications in structural engineering and building construction. With the material number 1.0238, S390GD has a minimum yield strength Rp0.2 of 390 N/mm² and is therefore one of the upper strength classes of galvanized structural steels. Hot-dip galvanizing in accordance with EN 10346 ensures a homogeneous zinc coating on the steel surface, which effectively protects the base material against corrosion and significantly extends the service life of structural solutions. By selecting different coating variants – +Z, +ZF, +ZA, +ZM and +AZ – the material can be precisely adapted to the respective environmental conditions and stresses.

S390GD is characterized by its excellent combination of high strength, sufficient ductility and long-lasting corrosion protection. Key mechanical properties can be found in the table above.

The very high minimum yield strength ensures a high load-bearing capacity under dynamic and static loads. The elongation at break of at least 16 % ensures sufficient deformability to compensate for stresses in profiling and bending processes and to prevent cracking.

The available coating types offer specific advantages for different application scenarios:

In addition, S390GD has a homogeneous microstructure, good weldability and precise dimensional accuracy, which facilitates further processing in cutting, bending and welding processes.

Thanks to its high strength and reliable corrosion protection, S390GD is used in a wide range of construction applications:

The choice of a suitable coating allows maintenance intervals to be extended and the life cycle costs of structures to be sustainably reduced.

With a minimum yield strength of 390 N/mm² and a tensile strength of at least 460 N/mm², the hot-dip galvanized steel S390GD in accordance with EN 10346 offers a first-class combination of strength, formability and corrosion protection. The wide range of coating variants makes it possible to adapt the material precisely to a wide variety of environmental and operating conditions – from moderate to aggressive maritime or thermally stressed environments. S390GD is therefore an economical, durable and technically mature solution for modern construction projects where the highest load-bearing capacity and resistance requirements must be met.
