Bridge Steel

Clean Steel with Strict Refining Standards

    Chinese bridge steel plates are designed for the fabrication of highway bridges, railway bridges, long-span bridges, and other heavy-load steel structures where strength, toughness, and long-term durability are essential. Produced in accordance with Chinese standards such as GB/T 714, these grades are widely used in both domestic infrastructure projects and international bridge construction.

    Common grades include Q235qC, Q345qC, Q370qD, Q420qD, Q500qE, Q550qE, Q690qE, and weather-resistant bridge steels such as Q345qNH. These materials offer reliable weldability, excellent low-temperature impact performance, and consistent mechanical properties, making them suitable for demanding structural applications in different climates.

    As a Chinese bridge steel supplier, CEHE Steel provides stock plates and customized processing services, including cutting, blasting, drilling, edge preparation, and third-party inspection. Whether you are sourcing bridge steel for new construction, bridge rehabilitation, or large infrastructure projects, we can help match the right grade, thickness, and delivery condition to your project requirements.

    Bridge steel is a structural steel specifically developed for bridge construction. Compared with ordinary structural steel, it offers better weldability, toughness, and long-term structural reliability.

    Most Chinese bridge steel plates are manufactured according to GB/T 714, which specifies chemical composition, mechanical properties, and testing requirements for bridge applications.

    The appropriate grade depends on factors such as design load, service temperature, welding requirements, corrosion environment, and applicable project standards. Our team can recommend suitable grades based on your technical specifications.

    Many Chinese bridge steel grades are designed with specified impact toughness requirements, allowing them to perform reliably in cold climates. The required impact testing temperature depends on the steel grade and project specification.

To receive an accurate quotation, it is helpful to provide the steel grade, plate dimensions, quantity, technical standard, delivery condition, destination port, and any processing or inspection requirements. This allows us to recommend the most suitable supply solution and delivery schedule.
