According to the definition in the old version of the JB/T 4712-2007 standard for container supports, the two holes on the rib plate of the saddle-type support are used for static grounding； Another theory is that it is used for lifting. 2. The material required for the equipment’s static ground plate is stainless steel or galvanized steel, while the supports are made of carbon steel or low-alloy steel. So are the two holes on the rib plate used for static grounding? Can it be used for static grounding?
How should rust prevention be considered? Does rusting affect conductivity?
No need. It was used for grounding in the past, but carbon steel rusts easily; nowadays, separate stainless steel grounding plates are welded in place, so those two holes are no longer used
Static grounding hole; however, the equipment we produce is equipped with a stainless steel grounding plate that is welded in place.
