The present invention relates to an alloy-coated steel sheet comprising: a steel sheet, and Al—Mg—Si—Zn alloy layer positioned on the steel sheet, wherein the Al—Mg—Si—Zn alloy layer comprises a Mg—Zn alloy phase, and wherein the Mg—Zn alloy phase comprises MgZnand MgZn, and the Mg—Zn alloy phase further comprises at least one of MgZn, MgZn, MgZnand MgZn.

Alloy coated steel sheet

Provided are an alloy coating steel plate and a method of manufacturing the same, and in this case, the alloy coating steel plate includes a steel, and an Al&#x2014;Mg&#x2014;Si alloy layer positioned on the steel plate, wherein the Al&#x2014;Mg&#x2014;Si alloy layer is formed to include Mg&#x2014;Si alloy grains in an alloy layer configured in an Al&#x2014;Mg alloy phase.

Alloy-coated steel sheet and manufacturing method therefor

Provided is an alloy-coated steel sheet and a manufacturing method thereof. The alloy-coated steel sheet includes: a steel sheet; and an Al&#x2014;Mg&#x2014;Si alloy layer disposed on the steel sheet, wherein the Al&#x2014;Mg&#x2014;Si alloy layer has a form in which Mg&#x2014;Si alloy grains are included in an alloy layer consisting of an Al&#x2014;Mg alloy phase.

Alloy-coated steel sheet and manufacturing method thereof

An exemplary embodiment of the present invention provides a coated steel sheet on which a magnesium-aluminum alloy coating layer is formed, including: a steel sheet; and a coating layer configured to include a first magnesium-aluminum alloy layer formed on a top surface of the steel sheet and a second magnesium-aluminum alloy layer formed on a top surface of the first magnesium-aluminum alloy layer, wherein a magnesium content of the first magnesium-aluminum alloy layer is higher than that of the second magnesium-aluminum alloy layer.

Magnesium-aluminum coated steel sheet

An ultraviolet rays shielding hat having a sun visor is disclosed. The hat includes an elastically circular band having an outer periphery, a plurality of guide supports attached to the side portions of the outer periphery, wherein said each guide support has a guide groove in each of a top side and a bottom side thereof, an inner support disk having an inner surface and an outer surface, wherein a slider is attached to the inner surface of the inner support disk and has a pair of guide rails inwardly extending therefrom, wherein the guide rails are slidably carried in the guide grooves, wherein a guide shaft extends from a central portion of the outer surface, and an outer support disk having a side engagement opening and a central engagement hole, wherein the guide shaft of the slider is rotatably engaged in the central engagement hole, wherein each side end of the sun visor is fixedly received in the side engagement opening.
