A gangway is an escalator that is installed on both sides of the ship for personnel to board or disembark. It is made of wood or metal. It consists of the upper and lower platforms, ladder frame, ladders step, railing handrail and lifting device, etc. When the ship is sailing, it is hoisted, folded and stored on the deck. When used, it is lowered and suspended from the side. Gangway installations are generally used for passenger ships and other types of large and medium-sized ships.
5454 marine grade aluminum plate sheet As an aluminium-magnesium alloy, it combines moderate-to-high strength with excellent weldability. Like 5154, 5454 marine grade aluminum plate sheet is commonly used in welded structures such as pressure vessels and ships.
China’s marine transport has reached a certain scale. In addition to the rapid economic development, the shipbuilding industry is also advancing by leaps and bounds. The ship is accompanied by moisture and rain, easily leading to corrosion and damage, and the ocean salt easily leads to premature corrosion of the ship base. Today, reducing the quality of the ship structure is also a crucial part. 3000 series of aluminum alloy can be used as a series of marine alloy aluminum.
5083 marine aluminum plate is a high value-added aluminum products, and in recent years it has become a large number of large aluminum manufacturers’ strategic direction. 5083 marine aluminum is getting more and more in market supply, with uneven quality. As the marine aluminum plate on the performance requirements are relatively high, which also to customers in the purchase of 5083 board is to increase the requirements. Choosing high-quality 5083 marine aluminum plate, customers can in the latter part of the production achieve better economic benefits.
5083 Shipbuilding aluminum plate has good forming performance, corrosion resistance, welding property and medium strength, and reach the standards of marine transportation industry.
5083 Marine aluminum plate with low density, high strength can reduce the application of heavy ship advantage. The low density, high strength, high rigidity and corrosion resistance of aluminum make the aluminum ship 20% lighter in weight compared to ships made of steel or other alloy materials. This can reduce ship weight and reduce energy consumption.
Marine aluminum sheet is one of the emerging field of aluminum alloy products, now comes to be a rising trade which has a complete range of sizes, both the currently the focus for the process of transformation and upgrading of numerous domestic aluminum processing enterprises direction. Marin aluminum sheet is being used in areas such as ocean shipping. Thus, comparing with those of other ordinary aluminum alloy products, strict requirements of the requirement of process and the performance standards were necessary in marine aluminum sheet applications.
haomei Aluminum 5000 Series marine aluminum sheet products are mainly used for hull outer plate and other long-term contact with the sea parts of the plate. The main aluminum alloys includes 5083 aluminum alloy and 5086 aluminum alloy. Common status are divided into: H116 / H321 / O / H112. Specifications: thickness ≤ 30mm, width ≤ 2600mm, length ≤ 14000mm.
