Thanks,
I have a backyard patio cover that needs a fair amount of welding, but it needs to be done by a certified welder. I ordered the steel (6" x 6" and 4" x 4", 0.250" wall) pre-cut to the correct angles and lengths. Most welding could be done in a shop with final assembly and welds done on-site. The overall is around 20' x 20', 8' tall at the perimeter. PM me if this is something you might be interested in.
Cheers, Mark
