Our Story in Numbers

Established in 1968

Founded in 1968, our business began in modest premises with a simple goal – to provide reliable service and quality our customers could trust. As our reputation grew, so did our team and capabilities, eventually leading us to outgrow our original location and expand into larger facilities to better serve our customers. Despite this growth, we’ve remained a proudly family-run, independent business, built on strong relationships, hard work, and a commitment to maintaining the same personal service and values we started with over five decades ago.

20+ Staff

Our team is at the heart of everything we do. With over 150 years of combined industry experience, our knowledgeable sales staff are always on hand to provide expert advice and help customers find the right solutions. Behind the scenes, our loyal and hardworking warehouse team ensures orders are handled efficiently and accurately, supported by our dedicated finance team who keep everything running smoothly, with many long-serving members of staff who have been a valued part of the business for years.

Tens of Thousands of Projects

Over the years we’ve proudly supplied to projects across the UK and Ireland in numbers that have long since gone past our ability to keep count! From everyday developments to some of the most iconic and recognisable buildings, it’s been an honour to play a small part in so many important projects. Each one reflects the trust our customers place in us and the pride we take in supplying quality products and dependable service.
