You go girl! Don't let anyone put you down. Keep your mind on increasing your worth.From my understanding, purlins are 90° from the rafters and on top of them. If I take that understanding of their use & placement then, the rafters as securing points for the metal roofing panels would loose 95-98% of the surface area for securing to the rafters.
Am I missing the point of what your suggesting? Would you like some up close shots of the structural connection zones? The metal plates for screwing the beams together? I still also have the templet of the ~18" 2x4 rafter support I could take a shot of it to show the cuts and how it was shoe-horned into place?]
I have on record.... Since the building started last spring/summer.... No less than 12 storms in 2019/2020 to date with sustained winds in excess of 45mph. More then 6 of them had gusts above 60mph too. I have had gusts records as high as 72mph over the last 2 years, 80+ over the last 6 years.
So far. Absolutely nothing of the coop or run has even shown a sign of getting bent outta place.
Minor tangent, if I may....Please realize I'm not wanting to sound snarky or any thing in that direction. If anything my Better-half will be the first to tell me to acknowledge my value as I have humbly down played my worth all my life. I have gotten alot better over the last couple decades. I still have a ways to go.
