Standard:YB168,YB(T)10,ASTM
Materials:16q,16Mnq,16MnCuq,15MnVq,15MnVNq,14MnNbq,A709M(Gr.36.50.50W.70W)
Applications:It is used to rivet and bolt weld structure highway bridge, railway bridges and sea-cross bridge.
Bridge steel plate is a kind of special thick steel plate to manufacture bridge structure. Usually special bridge steel plate contains carbon steel and low alloy steel and the grade is marked q at the end of steel.
Bridge Steel Plate
Bridge construction carbon steel is used to rivet A3q and weld the bridge structure 16q; Bridge structure low alloy steel has 12Mnq、12MnVq、15MnVNq、16Mnq etc. The thickness of bridge steel plate is 4.5-50mm. Main applications is used to build railway bridge, highway bridge and cross-sea bridge etc. This steel need to have higher strength, toughness and bear the load and impact of rolling stock and have good fatigue resistance, low temperature toughness and atmospheric corrosion resistance.
