Aluminium is an advanced material for the shipbuilding and marine engineering. The lightness,  strong mechanical property and anti-corrosive property make it a preferred material for modern vessels. Vessels made with aluminium alloy are advantageous in terms of higher speed, longer duration, higher load capacity, and lower maintenance costs.

By virtue of the world's most advanced industrial aluminium extrusion products and high-end aluminium flat rolling products, Zhongwang Group has secured a position in the field of shipbuilding. At present, Zhongwang Group products are mainly used for hull base panels, rib panels, deck superstructures, fender plates, windscreen frames and superstructures for yachts and speedboats, living quarters and structural components of offshore oil drilling platforms, and primary structural portions of marinas.

Aluminiumwerk Unna AG. (Alunna), a high-end aluminium extrusion subsidiary of China Zhongwang based in Germany, has been in operation for more than a century. Alunna manufactures a myriad of high value-added aluminium alloy extruded products including seamless extruded and porthole extruded tubes. Being one of the three aluminium tube manufacturers with full set of licenses from the aerospace industry, Alunna holds certificates from the top aircraft manufacturers including Airbus, Boeing, Bombardier, BAE Systems, Gulfstream Aerospace Corporation and so on.
