Aluminum plate for ship deck

• 5052 Aluminum Alloy:
  • According to haomei aluminium, this non-heat-treatable alloy provides excellent fatigue strength and good workability, making it easy to form into various shapes.
  • It offers good resistance to marine atmospheres and saltwater corrosion and is a common, cost-effective choice for decks in smaller, economical vessels or interior parts.
  • It is often used for its good anti-skid effect when in a checker plate form.
• 5083 Aluminum Alloy:
  • Widely used in marine applications like yachts and cruise ships, it offers a great balance of high strength, excellent corrosion resistance, and good weldability.
  • According to marinealu.com, its high magnesium content helps it maintain performance in highly corrosive seawater environments.
  • It is often used for structural decking and is available in various tempers such as H116, H112, and H321.
• 5086 Aluminum Alloy:
  • Similar to 5083, the 5086 alloy is known for its low density, high tensile strength, and superior corrosion resistance, especially in saltwater.
  • It is widely used in naval and commercial vessels and features medium strength and good weldability.
• 6061 Aluminum Alloy:
  • This is a versatile, general-purpose, heat-treatable alloy known for its excellent mechanical properties and corrosion resistance.
  • It has good processing performance and is often used for structural components or exterior reinforcement like keel linings.
  • 6061 aluminum tread plate is often used for its anti-slip properties on boat decks. 

• Flat Plate: Standard flat sheets are used for the main structural decking, providing strength and a base for other flooring materials.
• Checker Plate/Tread Plate/Diamond Plate: These feature raised patterns (one bar, two bar, five bar, etc.) on the surface to provide excellent anti-slip performance, which is a crucial safety feature for any ship deck. 

• Corrosion Resistance: The material must resist constant seawater exposure and salt spray.
• Strength-to-Weight Ratio: Aluminum's lightness increases fuel efficiency and speed while maintaining structural integrity.
• Weldability: The material should be easily welded to form strong, crack-resistant joints for construction and repair.
• Certifications: Look for marine-grade aluminum certified by classification societies such as ABS, DNV, LR, or CCS to ensure quality and compliance with industry standards
