Chan Ye Xin Xi Wang·2025-08-13 01:24Core Viewpoint - The bridge slab market in China is experiencing strong growth driven by urbanization and increasing infrastructure demands, with a production volume of 1.34 million tons in the first half of 2025, representing a year-on-year increase of 3.8% [1][8]. Industry Overview - Bridge slabs are specialized thick steel plates used in bridge construction, made from carbon steel or low-alloy steel, designed to withstand loads and impacts with high strength, toughness, fatigue resistance, low-temperature toughness, and atmospheric corrosion resistance [2][3]. - The mechanical performance requirements for bridge slabs include yield strength greater than 345 MPa and tensile strength greater than 470 MPa [3]. Industry Chain - The upstream of the bridge slab industry includes raw materials such as iron ore, coal, and anti-corrosion coatings, as well as production equipment like blast furnaces and rolling mills. The midstream involves the manufacturing of bridge slabs, while the downstream applications include road, rail, and urban transit projects [4]. Current Industry Status - The number of highway bridges in China is projected to reach 1.1081 million by the end of 2024, with a year-on-year growth of 2.67%, and the total bridge length exceeding 102 million meters, reflecting a 7.02% increase [6]. - The import of steel bridge components has significantly decreased, with a 68.04% drop in quantity and an 87.09% drop in value, indicating domestic industry upgrades and changing international market conditions [10]. Key Enterprises - The Chinese bridge steel plate industry is characterized by a tiered competitive landscape, with leading companies like Ansteel and Baowu Steel leveraging their technological and production capabilities to dominate the high-end bridge steel market [12]. - Ansteel has developed a range of high-performance bridge steels and has been involved in major projects like the Hong Kong-Zhuhai-Macao Bridge [14]. Industry Development Trends 1. The demand for enhanced transportation infrastructure is driving technological innovation and product upgrades, with a focus on high-strength and durable materials [18]. 2. The industry is shifting towards green and low-carbon practices, with policies promoting the use of sustainable materials and technologies [19][20]. 3. Market demand is diversifying, with increased opportunities in both domestic and international markets, particularly in the context of the Belt and Road Initiative [21].
