Larsen steel sheet pile piling machinery products are divided into two types according to the production process: cold-formed steel sheet piles and hot-rolled steel sheet piles. In engineering construction, cold-formed steel sheet pile has a high cost performance, and in engineering application, the two can replace each other. Based on the advantages of steel sheet piles in construction, the General Administration of Quality Supervision, Inspection and Quarantine and the National Standardization Administration issued the national standard GB/T 20933-2007 drafted by Maanshan Iron and Steel Co., Ltd., Shanghai Marui Iron and Steel Co., Ltd., Metallurgical Industry Information Standards Research Institute, Panzhihua Iron and Steel Group Co., Ltd. and Laiwu Iron and Steel Group Co., Ltd. on May 4, 2007. According to statistics, at present, the annual consumption of steel sheet piles in China is about 30,000 tons, accounting for only 1% of the world, and it is limited to some permanent projects such as port, wharf and shipyard construction, and temporary projects such as bridge cofferdam and foundation pit support.
