Marine aluminum alloy ribbed plates are a high-performance, high-quality shipbuilding material and are widely used in the shipbuilding industry.

The shipbuilding industry uses friction stir welding (FSW) to produce aluminum plates from aluminum extrusions, which are widely used in ship superstructures, deckhouses, etc.

A stiffened panel is a critical structural component in shipbuilding, consisting of a skin plate and reinforcing stiffeners welded together. It significantly increases structural strength while reducing weight.
