The offshore drilling platform is mainly used for the offshore structure of the drilling well, and the drilling, power, communication, navigation and other equipment are installed on it. As well as safe life-saving and personnel living facilities, it is an indispensable means for offshore oil and gas exploration and development. It mainly has jack-up and semi-submersible drilling platforms.

Most offshore drilling platforms are currently made of steel. The high strength of steel and low maintenance costs are its advantages. However, in the application of steel, problems such as rust, short service life and high maintenance cost are gradually emerging. Therefore, it is of long-term significance for the development of offshore engineering equipment to find a new type of material that is close to the strength of the steel, has good durability and is beautiful in appearance. The advantages of light weight, high strength, corrosion resistance, low maintenance and recyclability of aluminum profiles can meet the needs of development.The common marine grade aluminum extrusions include:marine grade aluminum round tubing , marine grade aluminum i-beam ,  marine grade aluminium flat bar , marine grade aluminum square tubing and so on.
The specific advantages of marine grade aluminum profiles are as follows:

1) Light weight. Lightweight, strong aluminum profiles, Aluminum profiles are lightweight and easy to install, transport and store. The weight of the aluminum alloy profile is only 1/3 of the weight of the steel structural material.

2) Applicability is strong . It can adapt to a variety of complex and harsh environments and climates.

3) The combination is diverse and the appearance is beautiful. Due to the strong plasticity of the aluminum alloy, the aluminum alloy profile can be made into various beautiful structures, and the shape is more fashionable and beautiful.

4) Corrosion resistant and easy to maintain. All aluminum profiles are treated with oxidation protection and the aluminum profiles have a service life of more than 30 years.
