For the inside... mezzanine or something? Crane?

What’s the issue with roll ups? We have several installed with not much issue to speak of. I’m unable to use overhead on my big opening due to future top running bridge crane. Roll up is only option.
That is anti sag strapping. It looks loose but is mounted “tout” to the purlins and girts. Being in a coastal county, the building must meet 130mph wind load for 3-5 seconds sustained. The strapping keeps the purlins from twisting under wind load. One continuous piece from wall, roof, to other wall. There is also angle braces from each rafter to the purlins. This keeps the rafters from racking under a wind load. The building must have all this extra support to pass wind storm inspection so I can properly insure it.
I like my roll up in my home garage. Saves overhead space for sure. It just sucks because you cannot insulate very well with them.
Yeah, only 15’ eve height here. Should have at least gone 16’ now that I know. Lesson learned for the next one.
My 16x12 wind rated roll up is almost same price as my 8x10 wind rated overhead. Such crap I tell ya.
Is that cable bracing or solid rod on yours? All galvanize frame?
