The storage is going to be held to 20'. For Class III multi-row racks <= 16', I can make it work as it stands. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Joe Hankins Sent: Monday, April 09, 2007 11:30 AM To: [email protected] Subject: Re: Roof Deck You can't use the bottom of the tee as the roof height any more than you can use the bottom of a beam. In fact, the 22 in. deep tees create a much worse situation than a metal deck on joists and beams. If a fire starts anywhere other than under the channel where sprinklers are, operation will be significantly delayed.
