Hainan plant structure, Peng Jian steel, steel billboard Ltd. Dongguan Peng was built by steel. Steel Co., Ltd., Dongguan City, Peng Jian (dgpengjian.cn) Guangdong Dongguan, steel leader, over the years, the company is implementing scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Peng leader in steel construction with the staff warmly welcome all inquiries negotiations to create Peng Jian Steel a better future. Dongguan Steel is one of the main architectural features of the structure of the type of steel is a high strength, light weight, stiffness, and therefore for the construction of large-span and ultra-high, super-heavy buildings particularly suitable; homogeneous and isotropic material Well, is ideal elastomer billboard steel frame, the basic assumption that best meet the general engineering mechanics; material ductility, toughness, and can have large deformation, can well withstand dynamic loads; construction period is short; its high degree of industrialization, can high degree of mechanization of specialized production; high-precision, high-efficiency, sealed good, it can be used for the construction of the tank, tanks and transformers. The disadvantage is poor fire resistance and corrosion resistance. Mainly for heavy load-bearing skeleton workshop, plant structure by dynamic loads, plates and shells, tall tower and mast structures, bridges, and so the library span structures, high-rise and high-rise buildings and so on. Steel should be studied in future high-strength steel steel structure plant, greatly improving its yield point strength; in addition to be a new species of rolling steel, such as H-beam (also known as wide-flange beam) and T-shaped steel and steel sheeting, etc. to meet the needs of large-span structures and high-rise building. The anti-corrosion coating on steel processing research in recent years, the extraordinarily rapid development of steel buildings. Steel is widely used also revealed a series of shortcomings plant structure, the more serious is the steel corrosion. Corrosion protection of steel structures were reviewed. With the extensive use of steel construction, due to the characteristics of the steel structure itself, and based on the building's safety and durability of steel corrosion problem has become increasingly prominent. At present, the world each year due to the economic losses caused by corrosion of steel has been up to hundreds of billions of dollars; but due to an accident caused by corrosion of steel endanger the safe operation of the plant structure structure, corrosion caused a catastrophic accident has a lot to see. For welded steel structures and steel structures to withstand greater stress situations, and under stress, the corrosion will be faster.
