The construction of transportation infrastructure is an important support for steel consumption, covering railways, highways, ports, airports and other fields. With the rapid development of high-speed railways and urban rail transit, there is a strong demand for railway steel such as rails, turnouts, and contact network pillars. High-speed railways have extremely high requirements for the straightness and wear resistance of rails. Bridge steel structures, guardrails, signboards, etc. in highway construction consume a large amount of steel. With the development of smart transportation, the requirements for steel's anti-corrosion and weather resistance are constantly improving. Port construction, including dock structures, lifting equipment, containers, etc., require steel suitable for marine environments, and corrosion resistance is a key indicator. The terminal steel structure and runway facilities in airport construction have strict requirements on the bearing capacity and safety of steel. The rapid development of urban rail transit has driven the demand for steel in the entire industry chain, including vehicle manufacturing, rail systems, and station facilities, and promoted the improvement of urban rail special steel standards and technological progress.
