RE: Galvanized Rebar

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Title: Message
Hopefully, the galvanizing was performed properly. I once heard a story about some galvanized rebar that was delivered to a site and was accidentally dropped during erection. The rebar cage shattered into pieces. Apparently the galvanizing was not performed properly and caused embrittlement of the rebar. (You may want to whack the rebar cage with a hammer just to be sure!)

David,

Most likely not.  Galvanized rebar is stilled used by certain industries for corrosion protection.  Sewage treatment plants use to use it a lot.  It has lost favor over the years since studies have shown that although it will increase corrosion protection versus uncoated bars it is not a big bang for your buck.  Your only issue might be if you weld it, in which case you would probably want to remove the zinc near the welds.

The American Galvanizers Associations still pushes this and you can find literature on galvanized rebar at:

Galvanized Rebar





A contractor inadvertantly ordered galvanized rebar for some sign structure foundations.  I've never used galvanized rebar - are there any issues/precautions that I should be concerned about?
