Regarding the 60" round table that is a huge table and the small round plate legs might not handle them

we actually have (5) of these steel case black bases we can ge them powder coated to silver
They will probably handle the 60" top they are really heavy this 30" shown below table was over kill 
the round base is 28" and the post is 5" I am working on the price. 
I have to get a few powder coat quotes plus locate 2 more
