Storage with 3:12 Pitch Roof

Question asked by scottbrannen on Sep 4, 2020

I have a customer who ordered a premanufactured steel building.  This building is for the storage of solid timber (Class III) commodity, stored in an unheated building 112' X 310'.  The slope of the ceiling is 3:12 with eaves at 20' and the peak 33.75'.  Is there a way to sprinkler this project without adding a non-combustible ceiling under near the roof to make for a flat ceiling or do I just add an additional 30% to the dry system calculation for the sloped of the roof?
