The invention discloses a hot galvanized dual-phase steel surface processing method and belongs to the technical field of rolling of dual-phase steel. The hot galvanized dual-phase steel surface processing method comprises the following steps that a dual-phase steel plate is heated, specifically, the heating rule is low-temperature fast firing; rough rolling and finish rolling are conducted on the heated dual-phase steel plate; and cold rolling is conducted on the dual-phase steel plate subjected to finish rolling, specifically, the reduction rate of cold rolling is 50-60%. The hot galvanized dual-phase steel surface processing method can prevent shallow layer roll burst and surface layer burrs on the surface of the cold-rolled plate, therefore multi-point skip plating and an uneven zinc layer generated by a substrate with surface layer cracks and burrs in the hot galvanizing process are prevented, and macro peak lines are reduced.
