ASTM A709 Gr.36 Structural steel plate
ASTM A709 is a specification that covers carbon and high-strength structural steel plates intended for use in bridge applications. There are multiple grades of A709 and Grade 36 covers the structural steel made from mild carbon steel, such as A36. We can supply High-Strength Low-Alloy ASTM A709 Gr.36 Structural Steel Plate, mainly used in bridges building.
Specifications:
Thickness: 6mm-300mm
Width: 1500mm-4200mm
Length: 3000mm-18000mm
Heat Treatment: AR/Control-rolled/TMCP/QT
