Shuttering Ply Ok for Workshop ceiling???

[des606]

Hello,

Novice woodworker building my first workshop. I had been buying wbp ply for the walls and then saw shuttering ply in builders providers and thought well that looks like it'd work. Found out it was much cheaper. So is it ok for workshop ceiling?? , will be fitting 5 ft Fluoro battens , is there any need to have wbp ply for this purpose.

Any info appreciated , Cheers

But wbp ply is not a necessitly
