S235 Steel is a low carbon structural steel commonly used in construction and engineering. It is known for its good weldability and machinability, making it suitable for various applications, including beams, columns, and plates. The "S" in S235 stands for structural, while the number 235 indicates the minimum yield strength of 235 megapascals. This steel grade is part of the European Standard EN 10025, which specifies the technical delivery conditions for hot-rolled products. S235 Steel is often used in the manufacturing of bridges, buildings, and other structures due to its balance of strength and ductility.
