The invention discloses technology for producing a strip steel continuous hot-dip galvanized thin coating. Excessive zinc solution is scraped by an air knife after the strip steel is discharged from a zinc pot. The technology can guarantee the surface quality of the thin coating, is convenient to be switched with common coatings, and meets the production requirements of different coatings. The technology comprises the following parameters: the zinc solution comprises 0.14 to 0.18 weight percent of effective aluminum, 0.015 to 0.03 weight percent of Fe and the balance of Zn, wherein the temperature of the zinc solution is between 455 and 465 DEG C, the temperature for putting the strip steel into the zinc pot is between 410 and 470 DEG C, the cutting edge gap in the middle of the air knifeis 1.0 to 1.3mm, a distance from the air knife to the strip steel is 7 to 12mm, the height of the air knife is 150 to 380mm, and the wind pressure of the air knife is 20 to 45KPa. The technology is suitable for producing thin-coating galvanized plates.
