Steel Angle Bar S235jr 1.0038 Hot Rolled Angle Steel Bar

Hot Rolled Steel Angle Bar S235jr (designated by the EN standard material number 1.0038) is a fundamental and widely utilized structural component characterized by its distinctive L-shaped cross-section. As a carbon structural steel angle bar processed via hot rolling, it integrates reliable mechanical properties, excellent processability, and cost-effectiveness, making it an indispensable choice for numerous civil engineering, industrial manufacturing, and infrastructure construction projects that demand stable load-bearing capacity and structural integrity.

From the perspective of material fundamentals, S235jr (1.0038) adheres to European EN standards, where the "S" denotes structural steel, "235" indicates the minimum yield strength of 235 MPa, and "jr" signifies its quality grade with guaranteed impact toughness at room temperature. This material composition endows the angle bar with balanced tensile strength and ductility, enabling it to withstand moderate to heavy loads without brittle failure. The hot rolling production process further enhances the material's internal structural uniformity-by heating the steel billet to a high temperature above the recrystallization point before rolling, the angle bar achieves a dense grain structure, which not only improves its mechanical performance but also ensures consistent quality across the entire product batch.

In terms of processability, Hot Rolled S235jr (1.0038) Angle Bar excels in weldability, machinability, and formability. It can be easily welded using common welding methods such as arc welding, gas welding, and resistance welding, facilitating seamless assembly with other structural components like beams, columns, and brackets. Its good machinability allows for precise cutting, drilling, and milling to meet custom dimensional requirements of specific projects. Additionally, the hot-rolled surface, though not as smooth as cold-rolled products, provides excellent adhesion for subsequent surface treatments such as painting, galvanizing, or coating, further extending its service life in corrosive or harsh environments.

Regarding application scenarios and quality assurance, S235jr (1.0038) Hot Rolled Angle Bar is extensively employed in general structural frameworks, building bracings, bridge auxiliary structures, industrial equipment bases, and container framing. Its versatility stems from its ability to balance performance and cost, catering to both large-scale infrastructure projects and small-to-medium industrial manufacturing needs. All products comply strictly with EN standard specifications and undergo rigorous quality control procedures, including raw material inspection, in-process dimension monitoring, and final mechanical property testing. This ensures that each batch of angle bars meets the required yield strength, tensile strength, and dimensional accuracy, providing reliable structural support for end applications.
