Hot Rolled Angel Steel Ms Equal A36 S355 Ss400 Unequal Angle Bar

Hot Rolled Mild Steel (MS) Angle Bar, available in both equal and unequal leg profiles, is a critical structural component widely utilized in industrial construction, infrastructure development, and mechanical manufacturing. This product line covers premium carbon and low-alloy steel grades including A36, S355, and Ss400, all processed via hot rolling to ensure superior mechanical properties and structural integrity. The dual availability of equal and unequal angle designs enables tailored solutions for diverse load-bearing and framing requirements, making it a versatile choice for applications demanding reliable support and force transmission.

From a material perspective, the selected grades are engineered to meet global standard requirements and varied performance needs. A36, a widely accepted American ASTM standard carbon steel, features a minimum yield strength of 250 MPa and tensile strength of 400-550 MPa, offering excellent ductility, weldability, and cost-effectiveness for general structural applications. S355, compliant with European EN standards, is a high-strength low-alloy (HSLA) steel with a minimum yield strength of 355 MPa, providing enhanced load-bearing capacity and fatigue resistance for heavy-duty structural scenarios. Ss400, adhering to Japanese JIS standards, is a mild carbon steel with a minimum tensile strength of 400 MPa, boasting reliable toughness and processability, suitable for general engineering and construction projects.

In terms of structural design and manufacturing process, the hot rolling technique is central to the product's performance. By heating steel billets above the recrystallization temperature before rolling, the angle bars achieve a dense, uniform grain structure, enhancing mechanical stability and dimensional accuracy. The equal angle bars feature symmetrical leg lengths, ensuring balanced load distribution for framing and bracing applications. In contrast, unequal angle bars have dissimilar leg lengths, optimized for applications requiring asymmetric load-bearing or space-saving installations, such as edge reinforcement and specialized support structures. All grades exhibit excellent processability, allowing for easy cutting, drilling, welding, and forming to adapt to custom project specifications.

Regarding application scope and quality assurance, these hot rolled MS angle bars cater to a broad range of industries. A36 grade is commonly used in North American building frameworks, bridge components, and industrial machinery bases. S355 grade excels in European high-rise buildings, large-span bridges, and offshore structures. Ss400 grade is widely applied in Japanese civil engineering, automotive components, and light industrial structures. Both equal and unequal profiles find use in pipe supports, storage racks, and structural bracings. All products comply with their respective international standards (ASTM, EN, JIS) and undergo strict quality inspections, including material composition analysis, mechanical property testing, and dimensional verification, ensuring consistent performance and structural safety for diverse end-use applications.
