Marine grade aluminum plates are often used in the shipbuilding industry. Many places in the shipyard need to use marine aluminum plates, such as ship furnace channels, deck channels, maintenance channels, up and down stairs, etc.
In some occasions, marine aluminum plates are also used in places where seawater corrodes.

2, If the marine aluminum plate is welded by hand, there should be 3mm weld feet on both sides, and the end should be covered with fillet welds, and there must be no missing welds, virtual welds and meat bites.
3, After the welding is completed, the aluminum plate should be straightened.
4, The surface of marine grade aluminum plate should have metallic luster, no sharp corners, burrs and splashes.
