Marine aluminum profiles 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 profiles can effectively reduce the overall weight of the vessel, improving fuel efficiency.
Marine aluminum profiles are typically supplied in various shapes and sizes to meet different design needs. Common shapes include:
A cylindrical hollow profile made of marine aluminum, commonly used in piping, railings, and frames in shipbuilding and marine structures due to its corrosion resistance and high strength.
A flat, rectangular marine aluminum sheet or strip used for structural components, decks, and other flat surfaces on ships.
The advantages of Aluminum Bulb Flat Extrusions over other types of extrusions are significant. Compared to traditional extrusions such as angles or flats, bulb flats offer better performance in load distribution and structural reinforcement.
L-shaped or angled aluminum profiles used for reinforcing edges, frames, and supports in marine structures. They are valued for their ability to provide structural support and resist corrosion.
A T-shaped profile made of marine aluminum, used to connect or reinforce parts at right angles, commonly used in building frames and brackets on ships.
An I-beam or H-shaped profile used in marine applications that require high strength, commonly used in constructing beams, joists, and structural supports.
A hollow square aluminum profile used in frameworks, railings, and other structural applications where both strength and corrosion resistance are critical.
A U-shaped or channel profile used in drainage systems, cable management, and structural components in marine environments. It helps guide or support materials while resisting corrosion.
Marine aluminum profiles generally use 6082, 6061, 6063, and 5083 aluminum alloys.
