Why does zinc protect the edges of galvanized sheets?


Why does zinc protect the edges of galvanized sheets?

Furthermore zinc provides electrolytic protection because it is anodic to iron. Zinc is electrochemically more reactive than steel. Therefore it oxidizes, saving from rusting even bare steel spots near the coating. This characteristic is called "sacrificial" protection. Exposed spots like sheared edges of galvanized sheets,See all results for this questionsp.info What kind of coating is used on galvanized steel?Galvanizing means the application of a zinc coating on steel surfaces. Dipping the cleaned steel items into a bath of molten zinc (Hot Dip Galvanizing) is a common process. The coverage tends to appear somewhat rough and the lower edges may result thicker, depending on drainage and cooling.See all results for this questionsp.info What causes steel to Peel during hot dip galvanizing?The primary cause for peeling or delamination on heavy steel parts is the time it takes for them to cool off after dipping in the zinc bath. During the hot-dip galvanizing process, steel is heated to approximately 830 F (443 C) by immersing it in a molten zinc bath.See all results for this questionsp.info Hot-dip galvanized steel strip from thyssenkruppHot-dip galvanized steel strip from thyssenkrupp combines the advantages of batch and continuous galvanizing. The hot-rolled steel is zinc-coated continuously and unlike conventionally hot-dip galvanized slit strip its edges are also coated.
