Maximizing Anchor Longevity Through Superior Galvanizing
While anchors are designed to last ‘forever,’ their true lifespan is largely determined by the durability of their galvanized coating. Over time, galvanizing wears off due to abrasion and exposure, defining the effective life of the anchor.
Many sailors try to extend anchor life by painting, but paint wears out quickly and complicates later maintenance. Re-galvanizing is possible but not always practical, as most galvanizers focus on bulk jobs and are reluctant to accept painted anchors, which are difficult to clean and prevent proper zinc adhesion.

The Importance of Galvanizing Thickness and Quality
Galvanizing life depends heavily on abrasion resistance. Thicker coatings generally last longer, but if the coating is too thick, it can peel. Proper surface preparation is also critical—poorly cleaned steel results in weak galvanizing that can quickly deteriorate.
Typical engineering standards require a minimum galvanized coating thickness of about 70 microns. However, most engineered products are not subject to the heavy abrasion anchors experience when dragged through seabeds.
At Viking Anchors, we prioritize longevity by maintaining an average minimum galvanized coating thickness of 100 microns and carefully inspect every batch. The hot-dip galvanizing process naturally varies the coating thickness, but we specifically minimize the amount of raw zinc on the surface. While raw zinc looks shiny, it is soft and wears off rapidly.
Instead, we focus on encouraging the formation of iron/zinc (Fe/Zn) alloys, which form the durable, hard layer that provides optimal corrosion and abrasion resistance.
Unlike many other anchor suppliers, Viking emphasizes long-lasting corrosion protection by rigorous testing and maintaining superior galvanized coatings, helping to ensure your anchor stands the test of time.
