False ceiling and nothing above ??

Hey everyone looking to go into a premises where there is false ceilings but nothing above the ceilings are corrugated metal type in the unit and full height is about 14 foot  maybe a little taller? The part where the beams are needed would be 17ft  in length  The on site building team are suggesting wooden timber beams to mount the poles on. Have tried to get in touch with x pole but not got a response have mostly seen studios using metal/steel girders or some sort of metal frame work so was wondering if anyone has any advice on best way to mount the poles safely. Thanks in advance.
