LR Grade A steel plate is common strength shipbuilding plate which has good toughness properties,higher strength,strong corrosion-resistance,the processing properties,and welding properties.LR Grade A(LR/A) steel plates are used in manufacturing hull,maritime oil extraction drilling platform, platform,tube junction and other structural components.
Dimension of LR Grade A Steel Plate:
Thickness: 3mm-150mm
Width: 1220mm-4200mm
Length: 5000mm-180000mm
