Longkou Conglin Aluminum Alloy Boat Co., Ltd. is a subsidiary company of Shandong Conglin Group. Now we have introduced advanced aluminum welding and processing equipment from Germany and cooperated with Finnish Lamor Company on production technology of aluminum boats to develop and research aluminum alloy special workboats, yachts, assault boats, etc. The aluminum boats are usually used in oil production, port management, clear-up operation in inland river and sea, and also used in tourism and pleasure, rescue and relief work, border defense, anti smuggling, portal in the coastal waters and so on. The aluminum boats have been popular in developed countries. With the high-speed development of China' economy and the implement of Ocean Economy Strategy, there are so many sea-related traveling and leisure fisheries so that the market demands all kinds of special boats. This provides brilliant prospects for ship industry.

At present, Shandong Conglin Group offers many kinds of aluminum boats, which feature safety, comfort, beautiful appearance, shock resistance, corrosion resistance and light weight. They are the replacing products for traditional boats made by wood, steel and glass fiber reinforced plastic, and also play an important part in ship industry construction of our country. Aluminum alloy has good strength, but the weight is much lighter than steel. So if loading the same goods, aluminum boats will improve speed more easier than those made by other materials. Besides, the navigation is more stable and comfortable, and the operation is more flexible. As we know, the glass fiber reinforced plastic has more difficulty in being correctly maintained and is also non-degradable. If any damage happens, it will be hard to repair. But for aluminum alloy, it is easy to repair and recycle, so it can reduce the material waste and achieve the goal of environmental protection.
