  Make them from Aluminium rather than Steel or Concrete.

  Ahh.

  Wrong type of 'light'...

  I'd suggest a narrow cylinder with emmisivity & then put on some bloom.

  I think nowadays I have enough vdb's to create a nice hazy beam effect...  The shaders are wrong here but if you reduce the opacity of 
   or  

  and added a grainy texture, you would have something very convincing.

  If you're trying to make a hazier, god rays-type beam, you do that with some sort of low-density volume. https://www.daz3d.com/iray-light-volume-kit does this with a VDB, but you can make your own out of a regular old cube primitive by turning off thin-walled and playing with the subsurface scattering settings.
