Application > Prestressed Steel Strand Production Line Application Areas

With the construction of high-speed railways and highways, various railways, highway bridges, airport roadbeds, port terminals, etc. are developing towards large spans and large loads. my country is developing and researching large-size single prestressed steel strands to replace small-size multiple steel strands, which is convenient for construction and improves the safety and durability of prestressed concrete.

The economic benefits of using prestressed steel strands are significant in buildings with large spans and heavy loads. Prestressed steel strands are widely used in large public buildings such as stadiums, exhibition centers, theaters, shopping malls, office buildings, and terminal buildings. Another field with more applications is bridge and tunnel structures. Many suspension bridges and cable-stayed bridges at home and abroad are prestressed projects with mature technology. The use of prestressed technology in the reinforcement of serving structures is even more rich and varied.

The demand for prestressed steel strand products in the water conservancy industry is increasing year by year. The structure of water supply and drainage projects is constantly developing and updating. Clean energy such as hydropower stations is the future development direction. Prestressed concrete structures are increasingly widely used in the field of water conservancy construction projects. The crack resistance and durability of prestressed steel strands are also used to solve some structural technical problems in water conservancy projects.

The prestressed steel strands produced independently by my country have been used as the main reinforcement of the nuclear containment structure in the Ling'ao Phase II Nuclear Power Plant, breaking through the technical barriers and ending the foreign monopoly of steel strands for nuclear power. At the same time, the development and research of low-temperature resistant prestressed steel strands for LNG engineering has opened up the application of prestressed steel strands produced in my country in the low-temperature field of LNG, marking another technological leap for domestic steel strands. Corrosion-resistant and high-strength prestressed steel strands have played an important role in marine engineering such as offshore oil production platforms and offshore storage tanks.
