A hollow profile sealed at the end should have holes in the top and bottom.
In particular, with hollow profiles such as tubes and pipes that have been sealed at the end, zinc has to be able to flow in quickly and air has to escape quickly as well. Before galvanisation, the objects are suspended, with the galvanisation plant making as much use as possible of the holes located near the end of the object. These holes will determine the suspended position of the object and what the top and bottom is. There should be holes in the top to allow air to escape, and holes in the bottom to allow zinc to flow in and out.
