unbonded steel strand or monostrand

Recently, there have been significant developments in the field of non bonded prestressed steel strands. In terms of technological research and development, innovative achievements continue to emerge. According to the information of the China National Intellectual Property Administration, China Nuclear Power Engineering Co., Ltd. applied for the patent of "Prestress Calculation Method and Device for Unbonded Prestressed Concrete Containment Reinforcement", which can more accurately determine the prestress of steel strands under a preset single load, and provide strong support for the stress calculation of unbonded prestressed concrete containment design. Anhui Provincial Institute of Transportation Regulation Engineering Intelligent Maintenance Technology Co., Ltd. has also obtained a patent for "a non bonded steel strand tension detection device", which can significantly improve the accuracy of steel strand detection.

At the market application level, with the vigorous promotion of infrastructure construction, the demand for non bonded prestressed steel strands continues to rise. In bridge engineering, it can enhance bearing capacity, improve seismic performance, and ensure the stability and safety of bridges. In high-rise buildings, it can improve load-bearing capacity, reduce deformation, and ensure building stability. Subway, tunnel, water conservancy engineering and other fields are also widely used to meet the strict requirements of structural seismic resistance and durability in these projects. According to authoritative data, the market size of China's non bonded prestressed steel strand will reach approximately 35 billion yuan in 2025, an increase of 25% compared to 2020, and is expected to climb to 55 billion yuan by 2030, with a compound annual growth rate of about 7.8%.

Unbonded prestressed steel strands are playing a key role in various fields such as construction and transportation through technological breakthroughs, helping the industry reach new heights and providing solid support for various engineering constructions.
