The present invention provides a method for producing a sheet. The method includes providing a substrate, depositing a metal coating over at least one surface by dipping the substrate in a bath in order to obtain the sheet, wiping the metal coating by means of at least one nozzle projecting through at least one outlet a wiping gas onto the metal coating, the sheet being run in front of the nozzle, the wiping gas being ejected from the nozzle along a primary direction of ejection (E), a confinement box delimiting a confined zone at least downstream of the zone of impact (I) of the wiping gas on the sheet and solidifying the metal coating. The method satisfying: $\frac{Z}{d}?12\mathrm{and}{f}_{O_2}?\frac{{10}^{-4}}{W^2}\left(0.63+\sqrt{0.4+94900*W^2}\right)\mathrm{with}W=\frac{\sqrt{\mathrm{PdZ}}}{V}.$

Provided are a zinc alloy plated steel sheet and a method for manufacturing the zinc alloy plated steel sheet. The zinc alloy plated steel sheet includes a base steel sheet and a zinc alloy plating layer, wherein the zinc alloy plating layer includes a Zn single phase structure as a microstructure and a ZnAlMg-based intermetallic compound, and the Zn single phase structure has a degree (f) of (0001) preferred orientation expressed by Formula 1 below within a range of 50% or greater. [Formula 1] f(%)=(I.sub.basal/I.sub.total)100 where I.sub.total refers to the integral of all diffraction peaks of the Zn single phase structure when an X-ray diffraction pattern is measured within a range of 2 theta from 10 to 100 using a Cu-K source, and I.sub.basal refers to the integral of diffraction peaks of the Zn single phase relating to a basal plane.

A gas wiping nozzle manufactured from parts divided along the slit length direction and maintains a gap in the width direction over the length direction in high temperature atmospheres and a method for manufacturing a hot-dip metal strip. In a gas wiping nozzle, a first and a second nozzle member are each divided along the length direction X of a slit into a plurality of nozzle members. The dimension of a divided face of the first nozzle member is 1.5T1 or more in a section of the first nozzle member where T1 is the thickness of the first nozzle member in the width direction Z of the slit, and the dimension of a divided face of the second nozzle member is 1.5T2 or more in a section of the second nozzle member where T2 is the thickness of the second nozzle member in the width direction Z of the slit.

The invention relates to a device and a method for hot-dip coating a metal strip with a metal covering, wherein the metal strip is directed continuously through a melt bath, wherein the thickness of the metal covering present on the metal strip when it leaves the melt bath is adjusted by means of a scraping device, and wherein slag which is present on the melt bath is driven away from the metal strip leaving the melt bath by means of a gas flow. To prevent slag from coming into contact with the metal strip leaving the melt bath, the invention drives away the slag from the metal strip by means of at least one nozzle which is arranged in close proximity to the metal strip, that a gas flow which extends over the width of the metal strip is directed onto the surface of the melt bath.
