As a metallurgically welded, crevice-free, aluminum-steel transition joint Detacouple is the alternative to corrosion-prone mechanical fasteners in harsh environments. Our history and reputation for quality and integrity are why naval architects and ship builders continue to rely on our Detacouple structural transition joints to:
- Join aluminum superstructures to steel decks
- Join aluminum decks or bulkheads to steel hulls
- Fit components, such as pillars or walls, between steel or stainless steel and aluminum
- Fit steel components, such as engine mounts, to aluminum hulls
With Detacouple being manufactured and stringently tested to the Military Specification MIL-J-24445A and approved by the American Bureau of Shipping (ABS) it has become the standard for permanent, aluminum-to-steel welds.
By replacing mechanical fasteners, Detacouple structural transition joints provide strong, maintenance-free, aluminum-to-steel welds for thousands of structures aboard today’s marine vessels and offshore operations.
