- John
Metal-coated structural steel, such as Galvanized Steel S350GD, combines high strength with corrosion resistance through the protective layer of zinc. This material is perfect for uses that demand robust strength and enduring defense.
SteelPro Group’s S350GD galvanized steel is specifically designed for construction and outdoor structures, offering customized solutions to meet the unique needs of your projects.
S350GD Galvanized Steel Description
Galvanized Steel S350GD is a high-strength structural steel designed to withstand demanding applications. The “S350” designation indicates a minimum yield strength of 350 megapascals (MPa), ensuring its reliability and durability in structural settings. The “GD” refers to hot-dip galvanizing, a method in which the steel is submerged in molten zinc. This coating forms a protective layer that significantly enhances the steel’s resistance to corrosion, ensuring long-term performance even in harsh environments.
S350GD is particularly valued for its ability to bear heavy loads, resist rust and corrosion, and maintain durability over time, even when exposed to moisture, chemicals, or extreme weather conditions. These attributes make it an ideal choice for building construction, outdoor structures, roofing, and automotive components.
SteelPro Group offers S350GD in multiple forms—coil, strip, and flat—allowing for tailored solutions that meet the unique needs of your projects.
S350GD Galvanized Steel Properties
- High Strength: Minimum yield strength of 350 MPa, ensuring robust load-bearing capacity for structural applications.
- Corrosion Resistance: Hot-dip galvanization provides a durable zinc coating, offering excellent protection against rust and environmental degradation.
- Durability: Engineered to endure harsh weather conditions, chemicals, and humidity, making it perfect for exterior and industrial uses.
- Formability: Good workability for various manufacturing processes, including welding, cutting, and bending.
