What is the development trend of prestressed steel strand in 2025?

In 2025, the prestressed steel strand industry is standing at the crossroads of the times and ushering in unprecedented development opportunities and challenges. At present, technological innovation and market expansion have become the key directions to drive the industry forward, pushing prestressed steel strands from the traditional building materials field to a new journey of high-tech materials, and the application continues to expand. Below, we analyze the development context of this industry from four dimensions.

Ⅰ, Materials and industrial technology upgrades:

In order to improve the strength of prestressed steel strands and expand the application scope of products, the research and development of graphene-enhanced steel strands has entered the pilot stage, and its huge potential has opened up new imagination space for the future development of the industry.

In line with the "dual carbon" trend, the industry has achieved a qualitative leap in low-carbon production technology. Carbon emissions have been reduced by 45%, and the waste acid recovery rate has exceeded 98%, demonstrating the industry's outstanding achievements in green environmental protection. The new environmentally friendly coating technology with a zinc-aluminum-magnesium alloy coating ratio increased to 65%, and the induction heating technology with a 30% low energy consumption advantage have become the driving force for the industry's green manufacturing transformation.

Under the wave of intelligent production, mainstream enterprises have made plans and built intelligent unmanned factories with the help of the industrial Internet. The raw material selection accuracy can reach 0.01mm, artificial intelligence can accurately control the temperature, and the error is only ±1℃. The online stress monitoring system collects more than 2,000 production data per minute, and the production efficiency and product quality are both improved.

Ⅱ, Product performance and special products have achieved breakthroughs:

Prestressed steel strands have achieved breakthroughs in core performance indicators. The strength, toughness and corrosion resistance of ordinary products have been improved in all aspects. The tensile strength of high-strength steel strands exceeds 2000MPa, the relaxation rate is less than 1.8%, the elongation is not less than 4.2%, and the diameter tolerance is reduced to 0.08mm.

Special products are even more brilliant. Steel strands for marine engineering can resist 3,000 hours of salt spray corrosion, and the monitoring error of steel strands with optical fiber sensors is as low as 0.001%. The continuous length of a single strand of products used in cross-sea suspended tunnels exceeds 8,000 meters, meeting the stringent requirements of extreme environments and complex projects.

Ⅲ, Changes in emerging demands and sales models:

The rise of emerging industries such as new energy and intelligent transportation has injected new vitality into the prestressed steel strand market. The annual growth rate of demand for floating photovoltaic anchoring systems has reached 120%, and the procurement demand in the fields of hydrogen energy and intelligent transportation is strong.

In order to adapt to market changes, the sales model has accelerated its transformation. Blockchain technology realizes full-process product traceability, and the AI algorithm outputs the optimal configuration solution in 3 minutes. The deep integration with cross-border e-commerce has made online transactions in the Southeast Asian market account for 40%, opening up new channels for the international market.

Ⅳ, International challenges and technological breakthroughs coexist:

The prestressed steel strand industry has both opportunities and challenges. Seizing the opportunities of new infrastructure and improving the technical level are the key to winning in the competition. With the implementation of the EU carbon tariff policy, export companies need to conduct carbon footprint certification, which increases costs by 8-12% and weakens international competitiveness; India's capacity expansion has caused a huge price impact on the Middle East market, and the industry's competitive pressure has increased dramatically.

Faced with difficulties, the industry focuses on technological breakthroughs in key areas such as microstructure control technology, residual stress distribution optimization, and full life cycle database construction, striving to break through development bottlenecks through technological innovation.

Conclusion: 

As the final year of the 14th Five-Year Plan, the synergistic effect of technological innovation and market response will reshape the industrial ecology in 2025. Looking forward to 2025-2030, the prestressed steel strand industry has broad development space and is undergoing a deep transformation from "scale expansion" to "value creation". For enterprises, only by seizing the opportunities of new infrastructure and breaking through technical barriers in high-end application fields can they stand out in the fierce market competition and open a new chapter in the development of the prestressed steel strand industry.
