️Tank & Bund Construction
The TAN.GBI-72494 features a double-skinned design, comprising an inner primary tank enclosed within an outer bunded tank. This configuration provides 110% containment, ensuring compliance with environmental regulations and safeguarding against potential leaks. The tank is constructed from construction plate steel to BS EN 10025-2:2004 S275JR and mounted on full-width bearers for stability. The outer tank serves as a protective barrier, offering secondary containment in the unlikely event of inner tank failure.
