The time that steel remains protected from corrosion is proportional to the thickness of the zinc layer, and it is dependent on the climatic conditions, as shown in the graphic below.

HOT DIP GALVANIZING
Dutch English Select Language: This layer primarily consists of zinc carbonate, which, because it is almost insoluble, delays further corrosion. You can download and open this file to your own computer but DRM prevents opening this file on another computer, including a networked server.
We have no document history for this standard. The large amount of zinc provides excellent corrosion resistance in normal outdoor environments, but with the downside that its layer thickness is significantly above the thread clearance allowance, which this poses a problem for all threaded fasteners. 1064 the voice of the U.
It provides a very solid and durable corrosion protection.
This graphic should be consulted only for rough estimates due to unforeseeable local influences. The other solution provided by ISO is to tap the internal threads nuts to be a bit larger oversize so that 1684 mate with the galvanized externally threaded fastener boltwhich is called the oversize HDG system.
