A709-50 Structural Plate

Bridges are critical pieces of infrastructure, allowing safe passage where it previously was difficult or impossible. They connect communities and make it possible to ship raw materials to factories or finished goods to consumers. A key component of most bridges is high-performance ASTM A709-50 structural steel plate.

Benefits of ASTM A790-50 Steel Plate

ASTM A709-50 plate is a high-strength, low-alloy structural steel plate utilized primarily in the manufacture of bridges. A chemical composition of iron, manganese, carbon, and other elements enable this carbon alloy to exhibit improved toughness, durability, and resistance to harsh outdoor conditions. Here are additional characteristics of ASTM A709 steel plate Grade 50.

  • High strength-to-weight ratio
  • Heightened weatherability 
  • Excellent corrosion resistance
  • Good weldability 
  • Easy workability 

Typical Applications

ASTM A709-50 structural steel plate is an American Association of State Highway and Transportation-approved material type. A high strength-to-weight ratio means smaller quantities of this steel grade are needed to meet strength requirements, which improves efficiency while cutting costs. Although initially designed for bridges, the unique combination of corrosion resistance, weldability, and durability makes ASTM A709 steel plate Grade 50 perfect for a range of outdoor infrastructure applications.

  • I-Beams
  • Structural angles
  • Wide flange beams 
  • Structural channels
