HOW LONG DOES AN ANCHOR LAST WITHOUT CORROSION?
It is just impossible to quantify it outside of a controlled laboratory environment in as much as the different environments where it has been installed (climate, geology and biology) and its external incidents (installation and use praxis). Nevertheless it’s impossible to test in its multitude of variants.
The lifespan of an anchor under normal conditions (that is to say, without corrosion and / or wear enhancers) could be up to 25 years or even more. In case of being exposed to corrosion enhancers or a high frequency of use, its lifespan could be significantly reduced, even up to a few weeks and in cases of choosing bad material or a bad installation practice, it might even suddenly break due to the SCC (Stress Corrosion Cracking). And because of that is the periodic review of anchors essential.
