A709 Gr.42 is a low alloy, high strength structural steel with good weldability and toughness, suitable for the manufacture of bridges and other structural engineering components.

The following are the areas of application of A709Gr42:

• Bridge construction: for beams, columns and other structural components of bridges, especially in the construction of bridges subject to heavy loads and harsh environmental conditions.

• Building structure: used for structural frames of high-rise buildings, industrial buildings, etc.

• Heavy Machinery: Used in the manufacture of components for heavy machinery, such as excavators, cranes, etc.

A709 Gr.50 is also a high strength low alloy steel.

The following are the areas of application of A709Gr50:

• Bridge construction: as the material of main girders, deck plates, webs and supporting structures and other components, it is widely used in bridge projects such as highways, railways, sea bridges and urban viaducts.

• Structural steel: Widely used in the steel frame structure of high-rise buildings, gymnasiums and so on.

• Mechanical fabrication: A709 Gr.50 steel plate is widely used in mechanical manufacturing, especially in the manufacture of components requiring high strength and good weldability.

• Pressure Vessels: Due to its excellent strength and toughness, A709 Gr.50 steel plate is also suitable for manufacturing pressure vessels.
