Zinc plated materials

The service life of the fixed lower off with ring zinc plated is relatively short. If you want to bolt a climbing route, please take this into account. This is because the necessary renovations will have a negative impact on the rock. For example, visually due to the many bolts that have been hammered in. On the other hand, the respective fixed point also costs more in total. This is because from the 1st climbing area rebolting at the latest, the overall effort is more expensive than a stainless steel product installed in the same way. We do not allow ourselves to make ethical judgments about what is good and bad. From a technical point of view, however, stainless steel products are clearly preferable if you want to set up a climbing route with expansion bolt .
