Slate is a totally natural product that has been used for centuries. As a natural material, it varies hugely in quality, but specifiers of SIGA Natural Slate can rest assured that the slates in the SIGA range are all guaranteed by SIG plc. A SIGA number specifically defines the quarry and selection of slate, guaranteeing traceability and consistency that is second to none.
All our slates are tested T1/S1/W1 in accordance with BS EN12326-1:2014 as a minimum, with some of our slates meeting French and Belgian Norms, and accreditation by Snowdonia National Park.
We are constantly reviewing the market to source the best natural slates from across the world, to bring you quality and consistency for your projects. Currently, we supply natural slate from Wales, Spain and the USA.
We select our slates from a wide range of quarries and they are categorised into ‘‘Excellence’, ‘Commercial’ and ‘Classic’ ranges, to assist you in the process of selecting the correct natural slate for your project.
