I will add this separate:
I ordered from United Carports online. This distributor was in San Jose. Just a middle man for my shop.
The steel provider was American Steel out of Joshua, Tx
The steel order from American Steel was sent to American Steel Carports and the kit was fabricated. Truss's to width, legs to length, siding to length bottom rail to length and with leg stands. All kitted and then their installation team brought the kit on a trailer and assembled.
My carport install took about 4hrs. The shop 2.5 days. It was fully insulated too by them.
Both experiences were a 10! The shop did take a month longer to arrive due to a mix up in scheduling... It was right around Christmas... The delay did not bother me. Gave the concrete longer to cure!
