Brazilian Slate, Rio Graphite | Valley Roofing

Brazilian Slate, Rio Graphite

The Brazilian Rio Black Graphite Slate originates from the beautiful Minas Gerais region of Brazil.  It has a flat, clean surface and subtle natural tone variations that make it unique.  The thickness of our Brazilian Rio Black Slate remains extremely consistent- between 5 and 7mm, ensuring that minimal sorting and grading is required.  Available now in prime grade, in sizes 500 x 250mm and 600 x 300mm,  LBS’s Black Rio Graphite Slate is a versatile choice for many roofing projects.

Please be aware that Brazilian Rio Black Slate is sedimentary stone meaning that it is much harder and denser than many other types of slate available. . Thus, extra care and attention is required when fixing. We recommend that you cut the slates using a disc machine, and employ hook fixing to secure the slates, rather than nail fixing.
