In the advanced technological world, the standard galvanized and galvanic coatings used for protection against corrosion will replace the coatings with higher corrosion resistance. In the world in this context; with hot swimming galvanized alloy baths created with different elements additions, work has been done especially for the steel sac and has been given to the commercial dimension. In this study, research and experimental studies have been carried out for the development of Zn-Al-Mg alloys that will show high corrosion resistance even in severe environmental conditions and for the extension of the limited corrosion life of the steel wire by cool-trapped steel wire surfaces. For the determination of the quality of coating Zn, Zn-Al and Zn-Al-Mg alloy coating samples were performed micro-structure analysis, salt side test and potentiostat analysis, coating test for the suitability to give plastic shape and the results were compared with each other. Adding 1 % of the Mg element significantly increases corrosion resistance. The highest corrosion resistance within the framework of the ASTM B 117 standard is achieved in Zn-%5Al-%1Mg alloy coating as +3000 hours. After the Potentiostat test, it was found that the open-circular potential value of the coating sample containing 100% Zn has the highest corrosion rate compared to other samples; the lowest corrosion rate (the highest corrosion resistance value) was found to belong to the coating sample containing Zn-5%Al-1Mg compared to the resulting corrosion rate.
