Zinc Coating Galvanized Steel Coil GSM120 0.12-4.0mm Color Coated Prepainted PPGI PPGL Q195 Slitted Edge
Why is galvanized steel coated with zinc?
The reason that the galvanizing process uses zinc instead of other
metals is that zinc oxidizes and experiences acid
corrosion “sacrificially” to steel. That means that when zinc is in contact with steel, oxygen and acids will attack the zinc
rather than the steel beneath it.
What is the difference between Aluzinc and galvanized?
There is a visible difference between the two as an aluminum-zinc
alloy metal appears to almost have a matte finish.
Galvanized metal corrodes linearly, and eventually, the zinc coating is completely depleted, whereas an aluminum-zinc
alloy experiences some corrosion, but on a smaller and less significant scale.
What is Z275 steel?
The specifications Z275 and Z600 refer to the zinc coating,
measured in grams of zinc or aluminium/zinc per square metre.
This measurement is the total coating mass on both sides of the steel.
