Galvanizing stringers with shear studs 2

[LobstaEata]

I was wondering if anyone knew if there would be any reason why shear studs couldn't be installed on steel stringers prior to hot dip galvanization. With proper coating procedures being followed, the pickling or dipping process shouldn't be a concern for material embrittlement, since the base metal and shear studs are both Grade 50. However could there be any transportation concerns that would preclude installing shear studs prior to dipping?

You won't be able to stack as many stringers on a truck unless the fabricator or shipper provides some special blocking.

Ironworkers generally dislike shop installed studs; it's cumbersome to get around. But that's life they'll have to deal with it.

Just do it. The finished product will be better, and the contractor will work around the transportation issues.

There are places that permit galvanizing of bridge steel? Maybe it's a climate thing, but here it is all weathering steel or nothing.

On topic, I hear more complaints about higher man hours for welding studs on site and calibrating stud guns for site conditions than I do about transport issues, unless you are looking at girders that will hit shipping height restrictions. With these being stringers I can't see shipping height being an issue.

I thought it was a requirement by OSHA that studs had to be applied in the field for worker safety?...
