Our bread & butter are bar joist box jobs, but we can do anything from bridges to solar array structures.
We do not do electrical pole or wind turbine work.
Some pretty large solar arrays. I can't tell specifics, but its pretty sick how big they can get. Even on top of existing structures.
What sort of treatment does steel used in outdoor construction needs to prevent oxidization? Does it always need a coat of paint or is galvanization enough?
Standard is Galv. only. Any paint on top of Galv. is typical overkill/cosmetic.
I hear China ships really low quality steel. Is American steel held to better standards?
From what I've seen yes. But i don't do much international work.
Do you usually do factories? Towers? Poles?
I am not sure if construction means usually permanent structures, or if it is a term for steelwork in general.
