Natural slate products can vary slightly in thickness and colour. Always allow a contingency for breakage during transport and installation. Due to the nature of Brazilian slate, cutting with an angle grinder or electric slate cutter is often recommended, and hook fixing may be advised to reduce wastage. Install in accordance with BS 5534.
