Anyone have design references or old catalogs from the former Mac-Fab Products? Looking for info on their Mac-Cor deck and shear connectors to evaluate structural modifications. Many thanks in advance!

The building was designed/constructed in 1965. A general detail/section indicates 1-5/8" 18-ga roof deck w/ minimum section modulus of 0.25. We measured 6" flute spacing & 24" panel width during a field visit. The deck spans between roof trusses and is topped with 1" insulation and...
Anyone come across a 1-5/8" roof deck in their work on older buildings? Flutes are about 6" wide and sheets are 24" wide. Structure was designed/built in 1965. Section modulus listed was 0.25 in3. Just looking for additional data.
Thanks!
I finally came across literature on older HH Robertson deck after contacting Epic Metals. Thought I would share with the group.
First file is for long span roof deck. Second file is for keystone deck.
Enjoy!

I have seen multiple references/specifications for Robertson Keystone deck without ever finding any information too! I have been wanting to add something on this deck to my collection for years, just can't find it...oh well, the search continues!
H57 - I would agree it is similar but the dimensions appear to differ.
I should mention these buildings were constructed sometime between the 50's - 70's (best estimate on LIMITED record drawings)...
I'm involved in a re-roofing project and need to check roof structure capacities for increase in gravity weight (due to insulation) and diaphragm shear, per IBC. For two of the handful of roofs I inspected, of which record drawings are not available, I was able to field measure the general deck...
I am in the process of analyzing an existing building built around 1974. Record documents specify 3" NF Inland Ryerson Metal Deck. Does anyone have old catalogs/design information for this deck - specifically diaphragm data?
I am evaluating an existing metal deck and concrete floor system. Original documents (1980's) specified a Mac-Fab B1A deck. My search for design info has come up empty thus far - hoping someone here could help.
