About Sentric

The Sentric Safety Group is a global set of safety technology companies with experts located around the world in six countries, united to create the long-term protection of people, productivity, and business reputation. For over a century we have manufactured trusted safety solutions with an unrivalled reputation, with one shared ethos: No compromise on safety.

The Sentric Safety Group was formed in 2016, although our history can be traced back to the second half of the 19th century when Paul Bouré designed and created the engagement lock device to ensure train traffic safety.

Our trapped key interlock brands, Castell, Kirk, and STI, have been used as part of integrated safety systems across a wide number of industries worldwide for over 100 years.

But that’s only the beginning.

Since 2005 Salvo has been a trusted brand in loading bay safety and efficiency solutions.

And Zonegreen have been providing products to the rail industry for more than 20 years, consistently meeting high standards, and have established an unrivalled reputation for quality, safety, and reliability.
