Guys, I need to build a car port so I can get more room in the garage to work
the cars that are not running. Ibm thinking of building it all out of
steel. Basic structure would be four posts with a perimeter frame using 11
gauge 3 inch square steel tubing for the posts and a 16b X 18b
rectangle on top of the posts. I would also use four 3b by 1.5 inch 14
gauge rectangle tubes as joists .
All would be butt welded. Covering would be corrugated steel panels. The
highest load would about 4 inches of snow.
Question: Am I pushing it by trying to spam 16 feet with a 3 inch 11 gauge
square steel tube?
I know some may think this is a dumb question but looking at other carports
it seems that they are all over the place, some are built like a bridge
while others look like they shouldnbt be able to stand by themselves.
What I havenbt seen is any built from 3 inch steel tubing.
Thanks
Bob Nogueira
