Re: Life span of painted steel

[Subject Prev][Subject Next][Thread Prev][Thread Next]
I have seen a lot of buildings with structural steel frames that are older
than 50 years.  There are examples of steel frame that are in good
condition after 50 years with nothing more than shop applied prime coat.
It depends on many environmental factors.  Here in Idaho we do not have the
corrosion problems that many areas have.

Subject:  Life span of painted steel

Does anybody have an idea, experience or data on the life span of
steel like trusses in an enclosed building like a gym, concert hall or a
church using only paint as rust protection. Do you know of any steel truss
or other structural steel member still existing after 50 years.

Thanks in advance
