The hot-dip galvanized steel S450GD 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 1.0233, S450GD has a minimum yield strength Rp0.2 of 450 N/mm² and therefore belongs to the highest performance level of hot-dip galvanized structural steels. Hot-dip galvanizing in accordance with EN 10346 ensures a uniform and resilient zinc coating that provides the steel with lasting protection against corrosion. Available coatings are +Z (pure zinc), +ZF (zinc-iron), +ZA (zinc-aluminum), +ZM (zinc-magnesium) and +AZ (aluminum-zinc), so that the material can be precisely adapted to different environmental conditions and stresses.

S450GD offers an excellent combination of high strength, sufficient ductility and proven corrosion protection. The key mechanical properties can be found in the table above.

These characteristics guarantee a solid load-bearing capacity even under high static and dynamic loads. The homogeneous microstructure of the hot-rolled base material ensures reliable dimensional accuracy and good weldability.

The different hot-dip galvanizing variants also offer specific advantages:

In addition, S420GD is characterized by a homogeneous microstructure, good weldability and precise dimensional accuracy, which enables economical further processing in cutting, bending and welding processes.

Due to its high strength and reliable corrosion protection, S450GD is used in a wide range of construction projects:

By selecting the right zinc coating, maintenance intervals can be extended and life cycle costs significantly reduced.

With a minimum yield strength of 450 N/mm² and a tensile strength of at least 510 N/mm², the hot-dip galvanized steel S450GD in accordance with EN 10346 offers an optimum combination of high load-bearing capacity, formability and long-lasting corrosion protection. The five available coating variants enable customized adaptation to a wide range of environmental and operating conditions. S450GD is therefore the preferred choice for modern construction projects where the highest demands are placed on strength, durability and cost-effectiveness.
