Metal Deck Perpendicular to Short DIrection Drainage

[reverbz]

Hey Guys,

I have a job I'm working on which is a long rectangular building. I am using open web steel joist connected to CMU walls. I have metal deck perpendicular to the joists and am wondering how drainage is dealt with when the deck is perpendicular to the short direction. Wouldn't water "pond" in the deck grooves? How have you guys dealt with this in the past or am I supposed to have subframing?

Thank you!

I'm in a northern climate but, here, the deck's corrugated profile would never be exposed to the elements as you've described. Rather there would be a roof buildup that would render the roof plane a flat surface.

Can confirm what KootK posted above is similar in southern US climates (Texas). Maybe just thinner insulation layer on top.
