I have metal support pole in my garage that is rusting out on the bottom due to melting snow from the cars during winter. I don't know how thick metal is but it looks bad. Are those poles filled with something or they hollow?
Your own garage, so probably one family house, so those columns are usually hollow. You can tap on it with a hammer to hear. The column is also 1/4" thick. Scrape the rust away and see how much of the metal you can remove. Those columns can rust away. I would recommend primer and paint, and trying to keep them dry.
carp's right,,, i always thought supporting columns had to be fill'd w/conc to meet fire code - heard it from an inspector/engineer/newbie laborer know-it-all on a job :laughing: maybe dan will chime in on this
I've had to cut a couple that were older and they were concrete filled. However, I do know that they can be hollow. If your unsure with the tap test then just drill a small hole in it to find out if there's concrete inside. In any case It does have to be addressed before it rusts out completely.
