After galvanizing, things WILL be a slightly different shape. The thermal
effects of being dipped into a pit full of molten zinc will do that.
You might get a buildup of zinc on the inside of a socket or the outside of
a pin that would need to be dealt with.
There might be some come-alonging and/or sledge hammering needed. I
haven't regalvanized tower sections, but I have worked with other steel
structural stuff. Qualitatively, I'd say that the deformation is less than
after, say, welding.
