Machines To Strip Wire, Machine To Strip Copper Wire
All scrap yards typically accept recyclable material from contractors,
but many of them act only as the middleman and resell the material to specialized processors outfitted with the necessary high-tech equipment to efficiently process the material.
Knowing whether or not a particular scrap operation has the capabilities to process the material on site can make a big difference in the price you receive for your material.
