What Is Marine Grade Aluminum Checker Plate
Compared with ordinary aluminum alloy plate and aluminum checker plates, marine grade aluminum checker plate has stricter processes and better performance standards. Among them, Haomei one bar aluminum checker plate has high market share in North America, especially the aluminum tread plate with a thickness of 1.6 mm or less. They have the following advantages:

1. Excellent corrosion resistance. Since ships are used in harsh seawater media and marine environments all year round, corrosion resistance is one of the main signs of marine grade aluminum tread plates.

2. It has high specific strength and specific modulus. The structural strength and size of a ship are closely related to the yield strength and elastic modulus of the material. It is usually difficult for high-strength aluminum alloys to have excellent corrosion resistance and weldability at the same time. 5xxx aluminum checker plate is often used.

3. Good cold and hot forming properties. Because the shipbuilding has to undergo multiple treatments such as cold processing and hot processing, the marine aluminum alloy must be easy to process and form, and still meet the requirements of strength and corrosion resistance after processing.

4. Excellent welding performance. At present, the automatic argon arc welding method is mainly used in ships. Good weldability means that the tendency of cracks formed during welding of aluminum alloys is small. 5XXX aluminum diamond plates have good welding crack resistance.
