Our vision is to build a Group that is globally recognised within our markets as the leading provider of pressure containment and control products and services to customers who operate in highly demanding, safety-critical environments where the consequences of product failure could be catastrophic.


Chesterfield Special Cylinders (CSC), has over a century of industry knowledge and expertise and is a world leading provider of bespoke, high-pressure gas containment solutions and services.

It is one of only five companies globally who can compete for ultra large cylinder contracts.

The Division comprises the three sites of Roota Engineering, Al-Met and Martract.

These businesses are leaders in their markets, with world-class lead times, highly specialised precision engineering skills and a blue chip customer base.
