Hot-dip galvanized steel
Hot-dip galvanized steel S350GD in accordance with EN 10346 is a high-performance solution for modern construction projects where high strength, good formability and long-term corrosion protection are required. With a minimum yield strength of 350 N/mm² and a tensile strength of at least 420 N/mm², S350GD ensures maximum load-bearing capacity even under extreme conditions. The six available coating types allow precise adaptation to a wide range of environmental and application scenarios – from temperate interiors to aggressive coastal regions or thermally stressed components. Construction companies and planners thus benefit from a durable, economical and technically mature material solution that meets the increasing demands of structural steel construction.
Want to know the difference between S350GD and other galvanized steel grades? GNEE STEEL's technical team is here to help. We'll break down the mechanical properties, corrosion resistance, and ideal applications of S350GD, so you can make an informed decision for your project.

Hot-dip galvanized steel S350GD
Heat Resistance
| Property/Limit | Temperature (°C) | Temperature (°F) | Remarks |
|---|---|---|---|
| Max Continuous Service Temp | 200 °C | 392 °F | Above this, properties may degrade |
| Max Intermittent Service Temp | 250 °C | 482 °F | Short-term exposure acceptable |
| Scaling Temperature | 300 °C | 572 °F | Risk of oxidation increases |
At elevated temperatures, S350GD steel maintains its mechanical properties up to a certain limit. Beyond 200 °C, the risk of oxidation and loss of strength increases, making it unsuitable for high-temperature applications without special considerations.
