Except for the fact the definition of solid shelving seems to support the case. '02 - 3.10.10...Shelves of wiremesh...more than 50% open and where the flue spaces are maintained shall be defined as open rack.
They are not advertising to us. They are advertising to people who have warehouses and don't know the issues about putting in "shelving". This is good for them to understand with this product the exiting sprinklers might be OK but with say a competing product like plywood they have a question to say the least. Chris Cahill, P.E.

They think this is special? It makes no difference when the rack is loaded with products, the sprinkler discharge is still obstructed. Who builds racks and puts nothing on them? It's a dumb advertising feature. Craig L.

Willis Sent: Monday, March 09, 2009 10:04 AM To: [email protected] Subject: Open Grating http://www.punchdeck.com/index.html I found this advertised in the current issue of a major magazine. It seems like it is mostly designed for in rack, but under applications it speaks of archive storage over large area. It also seems the key selling point to this is the ability to allow sprinkler water thru, thereby satisfying the requirement of open grate for buildings with sprinkler systems. I have never heard that before. Anybody else? R/ Matt Matthew J.
