fitting to metal deck
(OP)
Hi,
Is it possible, according to NFPA13, fitting to metal deck roof? I have DN40 branch lines and I want to fit they to metal deck roof.
The metal roof type:

The gage you have can be from 16 to 22.
Pipe size is given here http://www.sammysuperscrew.com/sammyxpress.htm
Looks like 22 gage can handle up to 2 1/2".

Also, it looks like you're driving two fasteners per hanger with the system you showed, vs one per location with the XP 35... of course you have to drill pilot holes with the Sammy, so that might be a even trade.
How many hangers are you putting up? Is this new construction or retrofit? The tool for installing the X-Press is a little expensive if you're only putting a couple of hangers up, but if you're doing a building it might be the ticket. Our field guys really like how easy they are to put in.

In design I suggest DN40 fitting to trapezoid sheet using Sikla roof hanger (link in the first post). But person, who opinion this project says that according NFPA13 it is imposible to hang pipe >DN25 to trapezoid sheets showing point 9.2.1.4.1 "Branch line hangers attached to metal deck shal be permited only for the support of pipe 1 inch or smaller in size..."
Because I'm from Poland I don't know what is precisely in USA "metal deck". Is trapezoid sheet roof a metal deck? Can i hang DN40 to trapezoid sheets?
Thank you for your help
PS. Sorry for my English ;)
RE: fitting to metal deck
you can only hang 1" pipe unless you have a hanger that is specifically listed for that use and the Sammy Xpress hanger is listed for this.
Dumb question, but what are the structural members that support the trapezoid sheeting?
