Hot-dip galvanized steel S320GD in accordance with the EN 10346 standard is a high-strength structural steel specially designed for demanding applications in structural engineering and building construction. With the material number 1.0250, S320GD has a minimum yield strength Rp0.2 of 320 N/mm² and is therefore one of the steels in the higher strength classes. Hot-dip galvanizing in accordance with EN 10346 ensures that a homogeneously applied zinc coating permanently protects the base material against corrosion. The available coatings +Z, +ZF, +ZA, +ZM, +AZ and +AS allow targeted adaptation to different environmental conditions and mechanical stresses, which means that S320GD achieves exceptional durability and cost-effectiveness in construction projects.

S320GD combines high strength with good formability and corrosion resistance. The minimum yield strength Rp0.2 of 320 N/mm² and a characteristic tensile strength (Rm) of at least 390 N/mm² ensure reliable load-bearing capacity even under changing load conditions. The elongation at break A80 of at least 17 % also allows safe forming and profiling processes.

The hot-dip galvanizing options offer the following specific advantages:

In addition, S320GD has a homogeneous microstructure, good weldability and excellent dimensional stability, which enables precise further processing in cutting, bending and welding processes.

Due to its high strength and reliable corrosion protection, S320GD has a wide range of applications in the construction industry:

The ability to adapt the zinc coating precisely to the respective application climate reduces maintenance cycles and significantly lowers the life cycle costs of buildings.

The hot-dip galvanized steel S320GD in accordance with EN 10346 offers an outstanding combination of strength, formability and corrosion protection with its minimum yield strength of 320 N/mm² and a tensile strength of at least 390 N/mm². The wide range of coating variants enables a tailor-made solution for a wide variety of environmental conditions – from temperate climates to aggressive maritime environments or areas with high temperatures. S320GD is therefore an economical, durable and technically mature choice for modern construction projects where the highest demands are placed on load-bearing capacity and durability.
