Marine and Offshore Engineering aluminium plat
Marine and Offshore Engineering
Aluminium products are largely used in the superstructures of marine and offshore engineering, such as ship body structures and bays. In addition, aluminium tubes with small diameter can be used as vessels, and larger tubes and rods can be masts and beam-columns etc. Sometimes, some profiles with small wall thickness are used in hull structures for the purpose of lightening as well.
The aluminium products from Signi Aluminium possess high strength, good processability and corrosion resistance, and completely meet the requirements of marine applications. Via the cooperation with international and domestic experts, Signi Aluminium masters the state-of-the-art production technologies of aluminium plates and profiles for marine, and is able to provide prospective supports for marine and offshore industries.
Signi Aluminium are capable of providing various aluminium alloy products for shipping and offshore engineering, which are mainly applied in LNG tank, ferry, yacht, patrol boat, the superstructure and lifting platform for other large vessels, and the drilling platform etc.
Classic alloy: 5052, 5754, 5154, 5086, 5083, 5383, 6005A, 6082
Product character: Superior corrosion resistance, good weldability, high fatigue resistance.
Hot rolled plate |
As one of China' s leading producers of flat rolled products, Signi' s aluminium sheet is produced from its own cast slabs or continuous cast coils, rolled down to customised thickness, gauge and tolerances. Our hot rolled plates are durable and deliver long lasting performance. Application areas: Electrical busbars and ducting, ships, boates, tanks, defence and industrial uses, aircrafts. |
