Product Detail
S350GD galvanized steel sheet/plate is low-alloy high-strength steel coated with a zinc layer for better corrosion resistance. It’s particularly suited for harsh environments, like marine climates, where corrosion can be a bigger issue. With a yield strength of at least 350 MPa, commonly used in industries like construction, automotive, and home appliances, for things like roofs, car bodies, and appliance exteriors.
The steel is made up of elements like iron, carbon, manganese, and silicon. This combination gives it the strength you need, while still making it easy to work with and resistant to corrosion.
The thickness of the zinc coating can be adjusted depending on what it’s being used for, improving corrosion resistance and adaptability. It’s also easy to process, whether you’re stamping, bending, or welding, so it works well for both cold-formed and hot-formed products.
S350GD galvanized steel sheets and plates are durable and recyclable which reduces the need for frequent replacements and helps cut down on waste.
