CORROSION
OF GALVANISED STEEL AND PARASITE ELECTRIC CURRENTS
All JOURDAIN products are galvanised in compliance with the 1461 standard in just the same way as all the other livestock equipment on the market.
However, depending on its environment, there can even be a risk of galvanised steel corroding in the medium to long-term in spite of its surface treatment.
The evolution of the composition of livestock rations, veterinary products, maintenance products, chemical sprays or a combination of the aforementioned can be factors that are capable of altering the zinc protective coating.
This mix works in the same way as a battery: contact with oxygen and acted on by the electricity present in the installation (parasite, static, telluric...), leading to the zinc’s structure being modified and the protective film altered. Due to this, the phenomenon of corrosion can appear in a very short time.
The end result being that there are multiple causes of corrosion that are sometimes difficult to detect in order to provide an explanation of why we are seeing what we do on posts.
HOWEVER, IN ORDER TO PREVENT THIS PHENOMENON, WE STRONGLY ADVISE THE FOLLOWING:
Double sleeve (first sleeve set in)
+ powder coated paint or heat-shrinkable protection sleeve
