Products Description
S235JR is classified as a non-alloy structural steel, specifically designed for use in construction and structural applications. The designation "S235" indicates a minimum yield strength of 235 MPa, while the "JR" suffix denotes that the steel has undergone a Charpy V-notch impact test at a temperature of 20°C.
This steel grade is widely recognized for its good mechanical properties, including high ductility and toughness, which are essential for structural integrity.

Products Application
Widely used in various building structures, bridges, vehicles, brackets, and machinery. For example, in industrial structures, S235JR H-beams can serve as steel bearing brackets, steel piles, and underground supporting structures, supporting loads up to 200–500 kN depending on the design.
In petrochemical and power plants, they are applied in equipment frames and pressure-resistant structures that require yield strength of 235 MPa and tensile strength of 360–510 MPa, ensuring reliable performance under moderate stress.
In shipbuilding and machinery manufacturing, S235JR H-beams are used in frame structures, decks, and hull supports, where elongation of 20–25% provides good ductility under dynamic loads.
For transport vehicles such as trains, cars, and tractors, they form beam brackets and chassis supports that endure both static and dynamic stresses. In ports and logistics facilities, they are used in conveyors and supporting structures, handling moderate loads while maintaining dimensional stability and ease of welding.
These applications highlight the good strength, toughness, weldability, and versatile performance of S235JR H-beams, making them suitable for a wide range of structural and industrial engineering projects.
