Anchor Bolts - Galvinized

[structbear]

I understand their is a spec or code put out by IBC concerning corrosion protection into concrete based on its diameter. Can anyone locate this for me

Thanks

Anchor bolts are usually not galvanized.

If there is a code requirement for additional corrosion protection, it will be in the code....look for it.

In my industry, anchor bolts are usually galvanized since our structures sit outside in the weather and sometimes near saltwater. We galvanize out a-bolts full length because they are stored outside before use, but many in our industry galvanize just the threads plus a few inches that stick out of the foundation but we are talking about #18 jumbo rebar bolts that are 12 feet long. Our bigger bolts are F1554 (IIRC) up to 3" diameter with a nut on the bottom.

Some Coal pulverizers installed indoors 20 or 30 years ago are popping their unprotected steel anchor bolts corroded to pencil thin-ness. That's longer than stated service life, but.............
