SSQ Canteverde is a low-grade roofing slate, mined exclusively for SSQ in South-East Brazil. Low-grade slate is a sedimentary rock which has similar characteristics to slate (which is a metamorphic rock) and is frequently used as a roofing slate. Geologically it is approximately 100 million years younger than typical slate rock resulting in the material being brittle. Hook fixing method is recommended. In addition to passing SSQ's own, rigorous quality control tests, SSQ Canteverde roofing slate has been tested in accordance with EN 12326, carries the UKCA marking and is classified as ?W1-T1-S1'. SSQ Canteverde is a grey-green roofing slate. The colour is natural with striking shade variations. SSQ Canteverde roofing slate is covered by a 30-year guarantee
