The Keystone Group is the first steel lintel manufacturer to be awarded the ISO14001 on 23rd June 2010.

The Keystone Group is committed to the continuous development of our Environmental Management Systems, working in partnership with our specifiers, customers and suppliers.

By achieving this coveted international standard, we meet all relevant environmental legislation and throughout our business we continue to develop products that give social and environmental benefits to our customers and the construction industry.

Our accreditation of ISO14001 – which is still rare among construction material suppliers – sets us apart by demonstrating our focus on not simply what we do, but how we do it.
