Build mats (Golden Rainbow)

I am not liking this 9B surplus of build mat that recently popped up
that will probably like crash the whole construction based market

You can build mats on GR? What about rugs and carpets?

no more like drywall and steel or wooden beams. I mean its not really going to make your FMUs cheaper by much
and road and track maintain are the only ones that use alot of it

I bought the rest pretty much
took 4 countries and 1 enterprise to do it
