Steel sheet pile can be divided into cold-formed thin-wall steel sheet pile and hot rolled steel sheet pile according to production technology. In engineering construction, the application scope of cold-formed steel sheet pile is narrow, and it is mostly used as material supplement, while hot-rolled steel sheet pile is always the leading product in engineering application. Based on the advantages of steel sheet pile in construction, the State General Administration of Quality Supervision, Inspection and Quarantine and Standardization Administration issued the “Hot Rolled U-Shaped Steel Sheet Pile” national standard on May 14, 2007, and was formally implemented on December 1, 2007. At the end of the 20th century, Masteel Co., LTD., with the technology and equipment of universal rolling mill production line imported from abroad, produced more than 5,000 tons of 400mm U-shaped steel sheet piles, which were successfully used in the Nenjiang Bridge cofferdam, the 300,000-ton dock of Jingjiang New Century Shipyard and flood control projects in Bangladesh. However, due to low production efficiency, poor economic benefits, little domestic demand and lack of technical experience during the trial production, the production failed to continue. According to statistics, at present, the annual consumption of steel plate pile in China remains at 30,000 tons, only 1%% in the world, and is limited to the permanent engineering of some ports, docks, shipyard construction and other temporary engineering of building bridge cofferdam, foundation pit supporting.

PTH, headquartered in Keqiao District of Shaoxing City, has more than 200 emplyees and a long history. In 1998, PTH began to produces steel structureal parts. In those 10 years, PTH production emphasis has gone through the transformation from the production of door and window fittings to the protecting system of houses, then turns to the building structure , and finally upgraded to integrated housing production. After ten years efforts, the first container house was finished and exported to New Caledonia in 2008. Meanwhile,PTH gradually becomes a leader in the Steel Structure industry. Now, its main products can be divided into four categories, which are steel structure building, light steel villas, container house and Double-C Structure. The annual production capacity for different types of buildings can reach 500,000 square meters.
