Angel Steel Hot Rolled Carbon Steel 50*50*6 Q235 Q345c S235jr Grade Angle Iron ASTM Equal and Unequal Angle Steel

Angel Steel Hot Rolled Carbon Steel Angle Iron is a high-performance structural steel product characterized by its L-shaped cross-section, which endows it with excellent load-bearing capacity, structural stability and versatility in various engineering applications. This product line covers both equal and unequal angle steel, complying with ASTM standards to ensure consistent quality, dimensional accuracy and mechanical performance that meet international engineering requirements.

The specified dimension of 50*50*6 (mm) represents a typical equal angle steel variant, where the two legs are of equal length (50mm) and the leg thickness is 6mm-a specification widely used in medium-load structural scenarios due to its balanced force distribution and easy installation. In addition to this standard size, the product range also includes a full spectrum of equal and unequal angle steel, with unequal angle steel featuring legs of different lengths to adapt to asymmetric load-bearing needs and special structural designs, such as special-shaped frames and directional support components.

The angle iron is available in multiple high-quality carbon steel grades, including Q235, Q345C and S235JR, each tailored to different engineering strength requirements. Q235 is a common mild carbon structural steel with a minimum yield strength of 235 MPa, offering good weldability, formability and cost-effectiveness, making it suitable for general structural applications such as building frames, equipment foundations and light support structures. Q345C, a low-alloy high-strength steel with a minimum yield strength of 345 MPa, contains alloying elements that enhance its tensile strength and toughness, making it ideal for demanding scenarios such as high-rise buildings, bridges and heavy machinery frames where superior load-bearing capacity is critical. S235JR, a non-alloy structural steel compliant with EN 10025-2 standard, has a minimum yield strength of 235 MPa, tensile strength ranging from 360 to 510 MPa, and excellent weldability, serving as a reliable choice for construction and industrial structures with moderate strength requirements.

All angle iron products are manufactured through hot rolling, a production process that involves heating carbon steel billets to high temperatures and shaping them into the characteristic L-shaped cross-section. This process not only ensures the uniformity of the product's internal structure and mechanical properties but also enhances its ductility and impact resistance, allowing the angle iron to withstand bending, torsion and compression without easy deformation. The hot-rolled surface finish provides a rough, natural texture that facilitates welding, drilling and other post-processing operations, enabling seamless integration with other structural components.

Compliance with ASTM standards is a core feature of this product line, ensuring that all dimensions, mechanical properties and quality control processes meet international benchmarks. Key ASTM standards applicable to this angle steel include ASTM A36 (equivalent to Q235) for general-purpose carbon steel angles and ASTM A572 Grade 50 (equivalent to Q345) for high-strength low-alloy angles, governing parameters such as yield strength, tensile strength, elongation and dimensional tolerances. This compliance ensures the product's compatibility with global engineering projects and provides assurance of its reliability and durability in long-term service.

With its diverse specifications, multiple grade options, rigorous manufacturing standards and versatile applications, Angel Steel Hot Rolled Carbon Steel Angle Iron is widely used in building construction, bridge engineering, industrial equipment framing, power transmission towers, container racks and other structural projects. Its combination of strength, processability and cost-effectiveness makes it an indispensable structural component in modern engineering and manufacturing industries.
