3mm 4mm 5mm 6mm A36 S235jr S275jr A572 A572 Ss400 Mild Carbon Iron Hot Rolled Equal Ms Angle Steel

Hot Rolled Equal Mild Steel (Ms) Angle Steel is a versatile and essential structural component, distinguished by its symmetrical L-shaped cross-section and superior mechanical properties, making it a preferred choice for a wide range of industrial, construction and engineering applications. This product line focuses on equal angle steel, where the two legs of the L-shape are of identical length, ensuring balanced force distribution, easy installation and exceptional structural stability in load-bearing scenarios.

The product is available in a comprehensive range of leg thicknesses, including 3mm, 4mm, 5mm and 6mm, catering to diverse load requirements and application scenarios. These thickness specifications are carefully engineered to balance strength and weight efficiency: the 3mm and 4mm variants are ideal for light-duty structural applications such as light frames, decorative structures and small equipment supports, offering cost-effectiveness and easy processability; the 5mm and 6mm variants provide enhanced load-bearing capacity, suitable for medium-duty scenarios including building trusses, equipment foundations, and industrial racking, where structural integrity under moderate pressure is critical. All equal angle steel products maintain strict dimensional accuracy, ensuring consistent fit and compatibility with other structural components during assembly.

A key advantage of this product line is its wide selection of high-quality mild carbon steel grades, including A36, S235JR, S275JR, A572, and SS400, each engineered to meet specific mechanical performance requirements and international standards. A36, a widely used mild carbon structural steel, boasts a minimum yield strength of 250 MPa and tensile strength ranging from 400 to 550 MPa, offering excellent weldability, formability and ductility, making it suitable for general-purpose structural applications. S235JR, compliant with EN 10025-2, is a non-alloy structural steel with a minimum yield strength of 235 MPa and tensile strength of 360-510 MPa, known for its reliability and versatility in construction and industrial frames. S275JR, another EN-standard non-alloy steel, features a higher minimum yield strength of 275 MPa, providing enhanced tensile strength and toughness for more demanding structural tasks.

A572 grade steel, a high-strength low-alloy (HSLA) variant, offers superior mechanical properties compared to traditional mild carbon steel, with yield strengths varying by grade (e.g., Grade 50 features a minimum yield strength of 345 MPa), making it ideal for heavy-duty applications such as bridges, high-rise building frames and heavy machinery supports. SS400, a Japanese industrial standard (JIS) mild carbon steel, has a minimum yield strength of 245 MPa and tensile strength of 400-510 MPa, valued for its excellent weldability, formability and cost-effectiveness, widely used in general construction and manufacturing. All these grades are carefully selected to ensure the angle steel meets the structural demands of different projects while maintaining cost-efficiency and processability.

All products are manufactured using advanced hot rolling technology, a process that involves heating mild carbon steel billets to high temperatures (typically above 1000°C) and shaping them into the characteristic equal L-shaped cross-section through continuous rolling. This hot rolling process not only refines the internal grain structure of the steel, ensuring uniform mechanical properties throughout the product, but also enhances its ductility and impact resistance, allowing the angle steel to withstand bending, torsion and compression without brittle fracture. The hot-rolled surface exhibits a natural, rough texture that facilitates post-processing operations such as welding, drilling, cutting and painting, enabling seamless integration into various structural systems.

As mild carbon steel (Ms) products, these angle steels offer inherent advantages such as excellent corrosion resistance (when properly treated with coatings or galvanization), cost-effectiveness compared to alloy steels, and wide availability. They comply with international quality standards, including ASTM, EN and JIS, ensuring consistent dimensional tolerances, mechanical performance and quality control. This compliance makes the product suitable for global engineering projects, providing engineers and contractors with a reliable, high-performance structural solution.

With its diverse thickness options, multiple high-quality steel grades, advanced manufacturing process and versatile applications, Hot Rolled Equal Ms Angle Steel is widely utilized in building construction (frames, trusses, balconies), industrial equipment (frames, supports, brackets), infrastructure projects (bridges, power transmission towers), and storage systems (container racks, warehouse shelving). Its combination of strength, processability, cost-effectiveness and reliability makes it an indispensable component in modern structural engineering and manufacturing.
