SSQ in the UK
SSQ was established in 1983 to supply Spanish slate to the UK market. The company correctly identified a lack of supply of local materials to satisfy the thirst of an increasingly slate-hungry home market. SSQ maintains the largest natural slate inventory in the UK with a constant minimum of 2 million units.
SSQ in Europe and the Rest of The World
SSQ operates in 22 countries with a logistics office in north-western Spain and their own quarry in central Argentina. SSQ is both a supplier and quarry owner — this unique position means unparalleled quality control from source to site.
