metal edge gypsum plank data 1

[samdamon]

Seeking any span tables or manufacturer's data for this outdated roof deck system. The typical system is 2" thick by 15" wide planks with sheet metal edges. The web says a system like this was made by USG, but no other data available so far. Am evaluating an existing roof that was constructed with it. My guess is the roof dates to 1950's or '60's. Any data appreciated.
