Product Detail

Shanghai Metal Corporation is a Q390High Strength Steel Plate manufacturer and supplier.

Q390 High Strength Steel Plate is a low alloy high-strength structural steel. Good comprehensive mechanical properties, good weldability, cold and hot working performance, and corrosion resistance. C, D, and E grade steels have good low-temperature toughness.

Q390 High Strength Steel Plate is widely used in fields such as construction, manufacturing, and transportation. Used in the oil and gas industry for equipment, pipelines, and storage tanks, providing corrosion resistance and reliability. Used in automotive manufacturing for chassis, body structure, and safety components, providing excellent impact resistance and durability. Used in Building structure for building frames, stairs, roofs, walls, etc., providing strength and stability. Used in railway transportation to manufacture railway vehicles, tracks, and bridges, providing stable support and load-bearing capacity.

Due to controlling the entire production process, we can provide stricter tolerances than other products. This saves time for our customers as our steel plates can be installed immediately after cutting without the need for leveling.

If you want to know more about our Q390 high strength steel products or Q390 high strength steel plate price, please feel free to contact us, we will reply you within 24 hours.
