I am looking for an erecting company. 14x48 back to back.
I would suggest that you Google up "steel fabricator" or "sign fabricator" for your city, state and region, and also do the same to identify the national fabricators, such as Keeler.
Where are you looking to build? JK Custom Homes ( 937) 467-4963 would be glad to give you some prices
