S320GD (1.0250) Galvanized Steel Sheet/Plate

 

 

S320GD is a high-strength hot-dip galvanized low-carbon steel. The zinc coating on its surface provides added corrosion resistance and extends its lifespan. It contains elements like iron, carbon, manganese, and silicon, which give it good strength and formability.

 

The steel is easy to work with - it can be cut, bent, and stamped into various shapes, making it adaptable for different design and manufacturing needs. This flexibility makes it useful across a range of industries.

 

S320GD galvanized steel sheet/plate is commonly used in construction, automotive, and appliance sectors, especially for components exposed to harsh environments, like exterior walls, roofs, and car bodies. The zinc coating protects against moisture, acid rain, and other corrosive elements, making it ideal for areas with high humidity or fluctuating temperatures. It's also used in light industrial machinery and outdoor equipment.

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:

+Z (pure galvanized):
Standard corrosion protection for general conditions.

+ZF (zinc-iron):
Improved coating adhesion and increased resistance to mechanical stress.

+ZA (zinc-aluminium):
Optimized resistance in atmospheric environments.

+ZM (zinc-magnesium):
Extended protection in maritime and saline zones through passivating behavior.

+AZ (aluminum-zinc):
Combination of heat resistance and corrosion protection, ideal for high surface temperatures.

+AS (aluminum-silicon):
Especially for applications with extreme temperature influences and high corrosion loads.

 

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