Re: Galvanized Rebar

[Subject Prev][Subject Next][Thread Prev][Thread Next]
As is often the case in reports from the field when you are not personally
observing the work, the information tends to change.

I've now been informed that it is only the W5.0 steel wire for the spirals
that was galvanized.  The longitudinal rebars were not galvanized.

Thanks for the many respones.
