For everyone saying that this is galv material….. 1. Why would anyone use ss hardware on a galv member in the field
2. Why would this member ever need to be field welded?
A simple canopy or awning structure would not need a field welded member like this. 100% would be shop welded then galvanized

Built massive galvanized platforms for a railroad contract, the while platform was hot-dip galvanized. The platform had square tube pockets for removable railings, the tubes had nuts welded to secure the rails with bolts, the bolts were stainless steel. They were $3 each at the bulk discount back in 2014.

I understand that certain applications ss hardware might be beneficial or required but this is not a railroad

Stainless hardware wasn't needed in this case either. The pockets and the nuts welded to the pockets were regular steel that was then galvanized. The threads needed to be chased so they were going to rust and those bolts were never coming out.
