More common roof replacement is papermill
machine room.

Channel slabs are typically set on bridge
truss spanning 100-150'

Channel slabs weigh about half a double tee,
thus their use on long span trusses.
-
The environment in the papermill roof deck
is very corrosive, with temperatures 130-150 degrees, with 100% humidity
and and with the presence of chloride and sulfur ions.
