Hat Channel vs Square Tubing
I've been doing research, reading, searching, watching videos. I've found opinions but nothing definitive about the benefit of hat channel over square tubing in a roof raise.
What are the pros and cons of each? Is one stronger? Is one easier to attach the sheet metal to? It seems like it would be easier to source tubing, and weld it inside the hat channel on each end. So unless there's some benefit to hat channel that I'm not finding, I think I'll go with tubing.
Thank you for any input!
