Between then, our highly qualified team have 180+ years of experience in making food-grade tanks and 350+ years of engineering experience. 


In line with our commitment to efficiency, we adopt lean manufacturing principles. We wholeheartedly embrace these principles, aiming to deliver heightened value to our customers by optimising resource utilisation.

Our steadfast dedication lies in minimising waste and consistently enhancing our processes. This allows us to provide exceptional value, quality, and efficiency while making the most of our available resources.

We believe all aspects of tank design should minimise waste and maximise profit, not just during the manufacturing of the tank, but for the lifetime of the tank and its production.
