Larsen steel sheet pile

Larsen, as a new building material steel sheet pile cofferdam in the large-scale pipeline bridge temporary trench excavation retaining, retaining, retaining wall, sand docks, unloading field wall, retaining wall dike revetment, etc. play an important role in engineering . Not only do the green steel sheet pile cofferdam, environmental protection and construction speed, construction, low cost, has good waterproof function.

Steel sheet pile products according to production process by a cold-formed steel sheet pile and the two types of hot-rolled steel sheet piling. In engineering construction, cold-formed steel sheet pile narrow range of applications, most of the material as an application supplement, hot-rolled steel sheet pile has been the leading product engineering applications. Steel sheet piles in the construction work on the many advantages of Quality Supervision, Inspection and Quarantine, the National Standardization Management Committee 14 May 2007 issued a “U-type hot-rolled steel sheet pile,” the national standard, and December 1, 2007 officially implemented. Late 20th century, the Hairui Ma Steel Co., Ltd. With the introduction of universal mill from foreign technology and equipment production line conditions, the production of the U-width 400mm more than 5,000 tons of steel sheet pile, and successfully applied to Nen River Bridge cofferdam, New Century Shipyard, Jingjiang Bangladesh, 30 million tons dock and flood control projects and other projects. However, during the trial production, low productivity, economic efficiency, low domestic demand, lack of experience and technical and other reasons, unable to continue production. According to statistics, China’s annual consumption of steel sheet pile to the 3 million tons, accounting for only 1% of the world%, and limited number of ports, terminals, shipyards and bridge construction and other permanent works cofferdam, excavation and other temporary works.
