Any issues with installing sidewall sprinklers under exposed corrugated steel decking if direction of spray is parallel with the flutes or is the decking considered a smooth flat ceiling regardless?
Good question, I could see it go both ways.
If you have specific sidewall, call their tech people and ask the question.
Or contact NFSA expert of the day and send them the question.
If not a member you might ask a field rep to ask the question::
