I have a customer costing up a new build using steel herringbone composite timber/steel type "Posi-joists" for first floor and flat roof areas. I called up the joist manufacturer and was amazed to hear that no-one had EVER asked them about installing electrics between, and support thereof.
He said the metal struts were cut VERY sharp.
I'd expect to probably clip direct one or two cables to the side of the wooden part, but closer to the surface than I’d like, (where 50mm doesn't apply to ceilings, but good practice does). - More cables wouldn't work.
It won't look nice, but cheap and cheerful. - Perhaps timber laths fixed centrally to the steel with tie-wraps would solve is most easily? Or maybe a split flexi conduit hung from the struts, - or is that a crap idea?
Who has worked with these? - Did you do it more elegantly?
