Meeting the Demands of Modern Shipbuilding with Ultra-Wide Plates
As shipbuilding moves toward larger and more integrated structures, traditional aluminum plates with widths of 1200mm–1600mm are no longer sufficient to meet design demands for single-sheet application, fewer welds, and cost reduction. The introduction of the 2600mm ultra-wide aluminum plate significantly reduces the number of joints, simplifies welding operations, and enhances the overall structural integrity and watertightness of the vessel.
5083 Marine Aluminum Plate: The Ideal Material for Shipbuilding
5083 aluminum is a classic magnesium-aluminum-silicon alloy known for its excellent corrosion resistance and anti-rust properties, making it the top choice for marine applications. It is especially well-suited for the underwater parts of ship hulls, which require materials capable of withstanding long-term seawater exposure.
Among the available temper options, 5083-H116 and 5083-H321 offer superior corrosion resistance and post-weld stability, making them more suitable than H111 and H112 for demanding marine environments. These tempers are widely used in critical areas such as hull bottoms and below-waterline side shells.

2600mm Ultra-Wide: A Leap in Shipbuilding Efficiency
Traditionally, shipbuilding relies on narrow aluminum sheets that require extensive welding. The 2600mm ultra-wide format brings several critical advantages:
Fewer Welds: Reduces the number of joints and weld seams, minimizing structural weak points and potential defects.
Higher Productivity: Less welding leads to faster construction times and lower labor costs. Large sheets also improve automation efficiency for cutting and forming.
Improved Structural Integrity: Fewer seams lead to better structural continuity, reducing stress concentrations and enhancing overall fatigue resistance and strength.
New Possibilities for Modern Marine Design
The 2600mm 5083-H112 ultra-wide marine aluminum plate is ideal for:
High-speed vessels, fishing boats, and yachts
Offshore wind platforms, pontoons, and workboats
LNG ships, cargo vessels, coast guard ships, and military vessels
