占全球35%市场！中国桥梁工程规模将破1.5万亿！

Core Viewpoint - In 2024, China's suspension bridge equipment industry achieved a total output value of 48.76 billion yuan, marking an 11.3% year-on-year growth, further solidifying its global leadership position [1]. Industry Performance - The number of large suspension bridges with main spans exceeding 1000 meters reached 19, ranking first in the world, with a continuous increase in domestic production rates and a clear acceleration in high-end, intelligent, and green transformation [1][2]. - The total number of bridges in China reached 191,400, with 11,300 being large bridges, reflecting a growth of 7.71% and 10.65% respectively compared to the previous year [3]. Market Outlook - The market size of China's bridge engineering industry is projected to reach 1.5 trillion yuan by 2025, accounting for 35% of the global market, with an expected growth rate of over 10% for large and extra-large bridge construction in the next five years [4]. - The manufacturing segment of structural components (mainly steel structures) contributed 21.58 billion yuan, accounting for 44.3% of the total output, while the cable system segment achieved an output of 15.62 billion yuan, representing 32.0% [4]. Technological Advancements - The proportion of high-strength cables used has reached 91.6%, with ultra-high-strength steel wire achieving engineering application, and the breaking force of a single main cable exceeding 100,000 tons [5]. - The adoption of intelligent construction methods is widespread, with BIM management coverage in large projects reaching 88% and prefabricated assembly application rates increasing to 67% [5]. International Expansion - In 2024, Chinese companies secured contracts for suspension bridge projects in Southeast Asia, Africa, and the Middle East totaling 12.86 billion USD, a year-on-year increase of 21.4%, with expectations for this figure to rise to 15.23 billion USD by 2025 [6]. - The export proportion of domestic equipment is expected to exceed 65%, with companies establishing overseas service centers and obtaining international certifications to deepen local engagement [6]. Future Trends - The development of suspension bridges is extending from crossing rivers and seas to complex terrains such as mountainous gorges, evolving from single-layer to double-layer multi-lane structures [8]. - The total industry output value is expected to reach 54.23 billion yuan by 2025, with an anticipated growth of 11.2% [8].
