Slates are the acknowledged leaders in Brazilian Roofing
slate, with over 15 years experience in supplying
slates to the United Kingdom, United States and other
countries within Europe. The Slate is quarried in
open cast quarries, where it is split to a nominal
thickness range of 04-06mm and 07-10mm. All slates
undergo a careful selection and are machined and quality
controlled using skilled labour.
