History of Kent Introl

HISTORY OF KENT INTROL

Since forming in 1967 as Introl Ltd, we’ve been through several changes of name and ownership. Having worked in dynamic sectors such as Oil & Gas, we’ve become accustomed to embracing and adapting to changes and using them to our advantage.
Changes of ownership over the years have given us the investment, connections and expertise to grow the business across multiple market sectors. We’ve done so whilst retaining our focus on the speed and quality of our manufacturing.
