Meshing PCB Guides

Hi,

Thanks to all of you for your valuable time and efforts putting in helping others.

Actually I need your valuable guidance on meshing the below parts, it is structure made from plastic PCB Rails, Metal PCB Guides with very complex shape to hold PCB's. had attached the images of the assembly and individual parts for your reference. 

 

horizontal members are plastic

vertical members are steel.

 

please guide me how to mesh this for getting accurate results.

 

Thanks in advance for your valuable time and efforts.

Thanks,

David
