The traditional steel sheet pile products are divided according to the production process, there are hot rolled steel sheet pile and cold bending steel sheet pile. But in recent years, there have been a lot of cold working combined with welding technology and other forms of composite processing type steel sheet pile, and combined with H steel or pipe pile formed by the combination of pile system, greatly enriched the steel sheet pile Market varieties. In the engineering construction, the hot rolled steel sheet pile has been the leading product of the engineering application. At present, the world's hot rolled steel sheet piles are u, Z type, type of atherosclerosis, the H type several major categories of dozens of specifications, atherosclerosis and Z type steel sheet pile production, processing and installation process is more complex, mainly are widely used in Europe and the United States, including China, throughout the Asia Pacific region much use of U-shaped steel sheet pile.
Generally, the thermal processing of steel plate pile has the advantages of size norms, stable performance, good quality, good waterproof, durability strong, has been widely applied to many engineering projects. Due to the limitations of production equipment and technology, at present, the world's largest hot rolled steel sheet pile width can only achieve 900 mm or so, the monolithic section modulus of the largest less than 4000 mm. Also because of the limitation of this, changes in the form of thermal processing plate pile section is also very difficult, on the market can only provide some specific section forms of steel sheet pile, for independent production design of steel plate pile section then it will consume a lot of investment, and design can not according to the design of customized products, which often leads to super designed to waste.
For cold working steel sheet pile, the domestic is relatively unfamiliar to it, or the existence of errors, especially for the cold processing of steel sheet pile of the latest development of the lack of understanding and dare not use. In fact, cold working steel sheet pile is the current international steel sheet pile of a development trend, many international large-scale steel sheet pile production companies, such as ESC steel, Arcelor steel, skyline steel, Oriental steel have been carried out in the cold processing products research and development. Cold working steel plate pile in production with processing is convenient, flexible, high production efficiency, customers can according to their own needs, tailored to meet the requirements of steel sheet pile; also have stable performance in terms of the quality of the products, good quality, high strength steel, strong durability and saving steel hotter processing steel sheet pile has great advantages.
