Cables run in Wolf Easi joist system

[Donkeybrains]

Hi Guys Im wiring a domestic dwelling that has the Wolf Easi joist fitted. The central web is great is running services, but how do you fix cables running with and at the normal to the joists? My first thought was mini trunking say 100 by 100, then we should to do grouping calcs. Why trunking well T&E is not self supporting as you all know. Drapping not a good idea, as there is a base layer of 100 Rockwool there to deaden sound from bellow. We could use cable ties, but that brings us back to grouping and they are plastic. Thanks in advance.

We have always used light gauge tray for these jobs and plastic ties now metal ties

The 3 metre, 150mm light weight trays slide into already fitted joists with no kinking. Problem solved. Any one else have to do it be advised I had a clear 3M space to lay trays flat and feed from.
