Inox Triplate®
High-Performance Transition Joint
Certified Quality and Mechanical Reliability
The vacuum explosion welding process represents a major improvement over open-air cladding method. It requires significantly less explosive material and reduces emissions by up to 250 tons of CO₂ per year. As a closed system, it also filters process gases before release, making Inox Triplate® not only a high-performance solution but also the most sustainable choice for modern engineering projects.
Critical Applications of Transition Joints
Triplate® transition joints are primarily used in:
- Shipbuilding: transition joints between steel hulls and aluminium superstructures, reducing weight without compromising safety.
- Offshore construction: connecting aluminium living modules to steel structures on platforms and support vessels.
Triplate® is trusted in naval ships, high-speed ferries, passenger vessels, and offshore projects operating in extreme environments.
Certified Quality & Proven Reliability
Inox Triplate® is the ideal choice for projects requiring structural transition joints between stainless steel and aluminium. Its proven design ensures mechanical strength, durability, and stability in naval, offshore, and heavy transportation applications. It simplifies integration into complex structures, reduces fabrication risks, and guarantees reliable long-term performance. Inox Triplate® delivers efficiency, safety, and confidence in every metal transition.

Frequently Asked Questions
What is Inox-Triplate®?
Inox-Triplate® is a vacuum explosion welded transition joint that connects aluminium structures to stainless steel. It combines an SA240 316L stainless base with titanium, pure aluminium and Al 5083 layers.
What is the difference between Triplate® and Inox-Triplate®?
Triplate® has a shipbuilding carbon-steel base for aluminium-to-steel connections. Inox-Triplate® has a 316L stainless-steel base plus a titanium interlayer, for aluminium-to-stainless connections.
Why does Inox-Triplate® contain a titanium layer?
The thin titanium layer separates the stainless steel from the aluminium, giving a sound, ductile bond between two metals that cannot be fused together directly.
Is Inox-Triplate® certified?
Yes. Inox-Triplate® is certified by DNV, and every sheet is dye-penetrant tested on the bond interface.
Where is Inox-Triplate® used?
In shipbuilding, wind turbines, offshore living quarters, LNG tankers, and trucks and trailers — anywhere aluminium meets stainless steel.
