Brazilian Rio Graphite

  • The LBS Rio Graphite slate comes from a slate quarry deep in the heart of the Minas Gerais region of Brazil
  • The Rio Graphite slate has a flat, clean surface and subtle natural tone variations that make it a beautiful option for a slate covering
  • The Rio slate is an extremely hard slate, and we recommend cutting with a disc machine and using slate hooks as well as or instead of traditional nail fixing
  • The LBS Rio Graphite slate is available in both 50x25cm and 60x30cm and comes in a standard thickness of 5-7mm
  • Rio Graphite slate has a low calcium content
  • The LBS Rio Graphite is fully certified and achieves the highest possible rankings in the BS EN 12326-1:2014 (W1, S1, T1)
