without digging up receipts............if my memory serves me correctly, it was a metal building company out of GA. Google metal carports and you will find them along with a great photo gallery. sturdiness........rated to 130mph.
the crew showed up at 7am and were gone by 10am. pay a little extra and get the thicker gauge metal. i am 6' 230 and walk on the top of it to clear branches and dropping from the oak tree.
