RE: H and J joists

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Don't let Vulcaft off the hook so easily.  Sometimes it takes a little
prodding to get them to look.  If you have the tag, it will tell you the
year the joist was built at least.  It also contains their file number.  I
have successfully pulled files that old, and even older.  I bet they have it
and haven't looked for it.  If you have a rep you deal with regularly, call
him first and have him apply pressure the home office.

Subject: H and J joists


Does anyone have any information on the time period for the transition
of H joists to J joists.  looking at the SJI 50-Year Steel Joist Digest
and conversations with a local distributor on joists leads me to believe
that H and J joists were built concurrently until 1978 when they were
superseded by K joists.  The project is in Anchorage, Alaska and I am
trying to determine the live load capacity of the mezzanine for the
building done in the early 1970's.  There are joists tags but the
manufacturer (Vulcraft) could not find information in their files.
