Galvalume steel is also called Aluminum-Zinc Alloy Coated Steel, Zincalume steel, aluminized zinc steel (aluzinc steel), SGLC. The galvalume metal is composed of 55% aluminium, 43.4% zinc and 1.6% silicon solidified at a high temperature of 600 ° C. Its whole structure consists of aluminium-iron-silicon-zinc, forming a dense quaternary crystal of an alloy.From the point of view of the degree of coating, the Galvanized Steel Coil is mainly the zinc plated on the coating, while the coating of the galvalume steel coil not only has zinc, but also has an extra part of aluminum.Galvalume steel sheet (coil) has better atmospheric corrosion resistance.
Galvalume Steel Sheet has excellent characteristics: strong corrosion resistance, 3 times that of pure Galvanized Steel Sheet; the surface has beautiful spangles, which can be used as building exterior panels.
The corrosion resistance of "Galvalume Steel Coil" is mainly because of aluminum, the protective function of aluminum. When the zinc is worn away, the aluminum forms a dense layer of aluminum oxide, preventing corrosion-resistant substances from further corroding the interior.

How to solve the patent crisis in China's LED industry
At present, the issue of intellectual property rights is related to the sustainable development of the entire LED industry. If it cannot properly solve a series of industrial crises, how to resolve the industrial crisis caused by LED intellectual property rights is a key issue in the development of China's LED semiconductor lighting industry. The following are comments from several industry insiders on patents. The core technology patent litigation will not happen for the time being. Sun Yinsheng Beijing Deli Intellectual Property Service Co., Ltd. has a strong intellectual property awareness in the LED industry. However, Chinese companies have not yet reached the international stage. The core technology is still in the hands of international giants. Domestically used chips are still foreign technology, so the litigation of core patents will not occur for a while, and the risk of litigation is mainly concentrated in the application field. Therefore, in the future, domestic LED companies will have many disputes in the application or packaging field. The government plays a leading role in the patent strategy. Li Wei, deputy director of the Industrial Promotion Department of the Guangdong Provincial Intellectual Property Office, has a government-to-business strategy divided into four aspects. The first government should foster the intellectual property awareness and intellectual property use of the guiding enterprises. Ability; the second is the government to promote the application of the industry, to guide enterprises to develop and use patent information; the third is to create a patent application environment, such as the participation of the platform construction; the fourth is very important, that is, must increase patent protection, let enterprises See the value of the patent. The patent belongs to its own standard belongs to the public. The standard of the deputy director of the high-tech department of Guangdong Science and Technology Department of Yundanping is different from the patent. The patent is its own thing as a whole. The standard is the public thing, which is the difference between public and private rights. Therefore, in the field of LED, private rights and public rights should be clarified. China's LED industry core patents need to be carefully explored. Guo Jinxia, ​​Institute of Semiconductors, Chinese Academy of Sciences, Semiconductor Lighting Research and Development Center. Everyone said that the domestic LED industry has no core patents. I do not agree that domestic LED patents are more than 100,000 pieces in this huge patent data. There must be gold in the Chinese, so the Chinese LED industry does not have patent ammunition, but does not go to it seriously. If you own a patent, you must take the initiative to do something. You don’t want to provoke litigation, but you have to issue some warnings to tell foreign companies that China also has knowledge. Property rights, entering the Chinese market must also respect the intellectual property rights of Chinese companies. The main problem is to solve the problem of exporting intellectual property rights. The LED market of the LED Industry Patent Alliance is far from enough. The Chinese LED companies should go international and participate in global competition. In participating in global competition, It is necessary to solve the intellectual property risks faced by export; it also regulates the intellectual property rights of our own industry and raises the awareness of entrepreneurs on the issue of intellectual property rights. Therefore, in this context, the work and direction of the LED industry patent alliance is outside the Lord.
