Please what's the exactly meaning in the Annotaion note of drawing?

[Runsong Lin]

Hi everybody,
As below image, here is a typical steel design drawing. But some annotation notes weren't be understood clearly. In fact, I hope to know what is exactlty meaning about "9.5Z12-31.8 15/16PE(D.N.)" ? Could you please give some advice or recommend some relative specification? Thank you in advance!

Please don't double post.

The 9.5 is the depth, the "Z" is the shape. The 12 is gauge of steel used. Not sure on the rest though.

9.5Z12 is a "Z" shape 9 1/2" tall made from 12 gauge material

31.8 15/16 I think is 31'-8 15/16" long

The abbriviations are more of a mystery but a girt manufacturer might know or they may be clarified on the drawing
I'm sure others in this forum will help much more than I

Is it common to dimension the building in millimeters and components in inches in your area? The x-bracing also appears to be in inches.
