350mm x 200mm Riverstone Ultra Quality Grey Natural Roofing Slate

Argentinian Riverstone Grey 5mm - 6mm Thick  (75 Year Guarantee)

• Riverstone Slate is a distinctive grey/green colour. The colouring is completely natural and will not fade even when exposed to the harshest of environments. Riverstone Slate is available with a dressed edge finish.
• Riverstone Slate has a slightly coarser grain size than most slates (due to its geological composition), which provides it with a rougher surface texture that imparts a more rustic feel.
• Samples of Riverstone Slate have been tested in accordance with, and comply with, the relevant sections of:

  

• BS 680: Part 2: 1971 – Pass
• French Standard P32/302 (1989) – Pass, Class A
• American Standard ASTM – Pass, S1
• German Standard DIN 58201 – 52206 – Pass
