Marine Aluminium Extrusions play a critical role in marine engineering, shipbuilding, and offshore facility construction. They are widely used in various marine environments due to their excellent corrosion resistance, lightweight, high strength, and good processing performance.
The lightweight nature of marine aluminum Extrusions can effectively reduce the overall weight of the vessel, improving fuel efficiency.
Aluminum tubes used in marine applications are commonly used in a variety of ship structures, including frames, railings, mast supports and other components
