Problems solved by technology
[0005] In addition, when cracks are formed in the coating layer during processing and forming of galvanized steel, the corrosion blocking effect of the coating layer is weakened, and the sacrificial corrosion protection of the coating layer at the cracked part proceeds rapidly, so the life of the coating layer is shortened, resulting in a decrease in corrosion resistance

Embodiment Construction
[0047] Hereinafter, examples of the present invention will be described in detail. The following examples are only for understanding the present invention, and do not limit the scope of rights of the present invention.
[0048] (Example)
[0049] The base steel sheets of Table 1 below were prepared by preparing hot-rolled steel sheets having the average grain sizes shown in Table 1 below, followed by cold rolling. During the cold rolling, the tension, rolling reduction, etc. of the steel sheet were adjusted to manufacture a base steel sheet having the surface roughness (Ra) and steepness shown in Table 1 below. In weight %, the composition of the basic steel sheet includes: C: 0.03%, Si: 0.02%, Mn: 0.15%, P: 0.01%, S: 0.01%, the balance of Fe and unavoidable impurities.

Abstract
The present invention relates to a plated steel material which can be used for an automobile, a household appliance, a building material, and the like and, more specifically, to a zinc alloy plated steel material having excellent corrosion resistance after being processed and a method for manufacturing the same.
Description
technical field [0001] The present invention relates to a plated steel material that can be used in automobiles, home appliances, building materials, etc., and more specifically, relates to a galvanized alloy steel material with excellent corrosion resistance after processing and a manufacturing method thereof. Background technique [0002] The galvanizing method that suppresses the corrosion of iron by cathodic corrosion protection has excellent corrosion protection performance and economical efficiency, and thus is widely used to manufacture steel materials with high corrosion resistance characteristics. In particular, hot-dip galvanized steel, in which steel is immersed in molten zinc to form a coating, has a simpler manufacturing process and lower product prices than electro-galvanized steel, so demand is increasing in all industries such as automobiles, home appliances, and construction materials . [0003] When hot-dip galvanized steel is exposed to a corrosive enviro...
