When all the D clips 7 have been set over the inter
sections and welded in place, the inside metal wall struc
ture is set in place.
The inside wall sections are what
might be termed triple channels. They have two narrow
channels 12 and a midchannel 13 about twice the width
This invention relates to metal walls, particularly insu

straps which we call horizontal girts. The channel sec

side the sections have a looped ?ange 14 and the other
