The invention relates to a steel plate provided with a zinc coating. At least one zinc layer is manufactured by a vacuum deposition coating method using a sonic steam jet, wherein the ratio of a pressure Pjet in a zinc jet chamber to a pressure Pchamber in a deposition chamber is between 2x10<-3> and 5.5x10<-2>. The invention also relates to a related manufacturing method. 本发明涉及一种设置有锌涂层的钢板，所述至少一个锌层通过使用声速蒸气射流的真空沉积涂覆方法制造，其中锌喷射室内的压强P喷射与沉积室内的压强P室之间的比在2×10-3至5.5×10-2之间。本发明还涉及相关的制造方法。
