ASTM A709 Grade HPS 50W Steel

ASTM A709 Grade HPS 50W steel is a high-strength, low-alloy steel specifically designed for bridges and weather-resistant environments.

ASTM A709 Grade HPS 50W Steel Brief Description

ASTM A709 Grade HPS 50W steel is a high-strength, low-alloy steel specifically designed for bridges and weather-resistant environments.

ASTM A709 steel plate refers to a high-strength, low-alloy (HSLA) structural steel plate that conforms to the ASTM A709 specification commonly used in bridge construction. A709 steel plate provides high tensile and yield strength, making it suitable for various bridge components, such as girders, trusses, and other structural elements.

Grade HPS 50W Steel Plate: This grade plate has a minimum yield strength of 50 ksi (345 MPa) and is characterized by its enhanced toughness and weldability. It is often used in bridges with high-demanding conditions and requirements.

Service Support
ASTM A709 Grade HPS 50W Steel

Fully controllable supply guarantee

  • Customized Specifications
    We offer A709 Gr 50W steel plates in thicknesses ranging from 8 to 300 mm. We can provide customized cutting services for length and width based on your engineering drawings or specific requirements.
    If the project requires higher toughness of the steel (e.g., for large-span bridges), we can also customize Z-direction performance steel plates (Z15/Z25/Z35) to ensure the steel plates’ resistance to delamination in the thickness direction, meeting stringent operational requirements.
  • Stable production capacity: With our modern rolling lines and quality inspection center, we have a monthly production capacity of over 5,000 tons, ensuring stable order delivery and avoiding delays caused by insufficient production capacity.
  • Logistics Support: Long-term collaboration with international freight forwarders to support various transportation methods, including sea freight (full container load/less than container load) and land transport (to ports);
  • We provide customs clearance assistance, including origin certificates and quality inspection reports. We also offer end-to-end tracking from factory to destination. This helps ensure timely delivery of goods.
