Light Guage Framing Connections

Mike,

Congratulations!  (Important things first!)

Z-sections are *very* susceptibal to lateral buckling of unsupported 
flanges.  With a canopy or a partially enclosed building, you will have 
uplift and the bottom flange will be in compression and subject to lateral 
buckling.  I typically use straps as X-bracing to provide lateral support to 
the bottom flange.
