Zusammenfassung:	The present invention relates to the technical field of ferrous metallurgy production, and to a zinc-aluminum-magnesium alloy coated steel containing V and B and a preparation method therefor. The present invention provides the zinc-aluminum-magnesium alloy coated steel containing V and B. A coating comprises the following chemical components in mass percentage: 0.4%-2.8% of aluminum, 0.5%-3.0% of magnesium, 0.005%-0.8% of vanadium, and 0.001%-0.20% of boron, with the balance being zinc and inevitable impurities, wherein Al/Mg is 0.8-1.5, and the total amount of vanadium and boron is 0.01-0.50%. The zinc-aluminum-magnesium alloy coated steel provided by the present invention can satisfy the requirements of a user for the corrosion resistance and formability of a steel, is particularly suitable for the fields of household appliances and automobiles, and has a good popularization and application prospect. La présente invention concerne le domaine technique de la production sidérurgique et un acier revêtu d'un a
