It was in 1992 that SSQ founder Ahmed El-Helw first met with Del Carmen’s owners in his search for the finest quality slate Spain had to offer. It wasn’t long before he realised he’d found what he’d been looking for. When it came to its aesthetics, durability and all-round performance, the slate produced by Del Carmen was among the best he’d ever seen, as Ahmed explains. “As quarries go, Del Carmen had it all – uncompromising quality standards, decades of expertise, and the most stunning blue-black slate with the longevity to last up to a century. “However, it wasn’t as simple as placing an order. Like any quarry, Del Carmen only had a limited amount of material they could supply, and any slate they gave to me was slate they couldn’t supply elsewhere. “I had to convince them to put their faith in me – a young businessman operating in a country they’d never supplied to before. But I’m delighted to say they did. “We trusted and respected each other from the very beginning – so much so that, when our agreement was finally made, it was with a handshake. Thirty years on, we’ve still never signed a formal contract.” “I’ll always be hugely grateful to Del Carmen’s owners for all their support and friendship.” SSQ Celebrates 30 Years Manuel Maestre Vega, Founder of the Del Carmen Quarry (left) and SSQ founder Ahmed El-Helw (right) In the decades since that first meeting in Spain, SSQ has used outstanding Del Carmen slate to roof thousands of buildings all around the world, with the material often handpicked by architects for its distinctive, faintly-rippled texture, deep blue-black colour and longitudinal grain. “I’ll always be hugely grateful to Del Carmen’s owners for all their support and friendship,” Ahmed continues. “Without them, SSQ wouldn’t be the business it is today. “Later in 2022, we’re hoping to travel out to Spain to celebrate properly with our friends at Del Carmen, and look forward to the next thirty years of cooperation.” >>Read more about SSQ in the news Previous article Roofing Contractor Suffers Breach of Contract After Payment DisputeNext article Commercial Work Propels Construction Growth to 6 Month High in January 2022 Share article You may also like View all News Featured Companies +3 26 February 2026 Glidevale Protect Strengthens Product Management Team with New Appointment Featured Companies +3 26 January 2026 Guardian Building Systems Launches New AI Training Programme Apprenticeships +4 15 January 2026 Build Your Roofing Workforce – Apprenticeships with Exeter College Featured Companies +4 20 November 2025 Protektor Wemico Marks UK Roofing Debut with West Temple Sheen Project Film Sign Up to Roofing Today Stay up to date with all of the latest news from Roofing Today by signing up to our weekly Bulletins… Sign Up Today Get in Touch Check out the latest issue 123 March-April 2026 View Now Past Issues Get in Touch
