Our Slate Quarries

Our Slate Quarries

SIGA Natural Slate is sourced from all over the world. Major slate producing countries include Spain, Wales, China and Canada.

A SIGA number specifically defines the quarry and selection of slate, guaranteeing traceability and consistency that is second to none. In order to further cement our commitment to provide quality natural slate, we launched our ‘Slate Operations Centre’, SIG Pizarras in 2007. Through SIG Pizarras, based in the heart of the slate quarrying region in Leon, Spain, we have access to:

  • A wide range of slate quarries for all types of slate
  • On-site full-time quality control personnel
  • Highly experienced slate procurement personnel
  • Custom slate sizes, headlaps and selection
  • Rapid and efficient logistics
