50X50X5 Angle Steel ASTM A36 A53 Q235 Q345 Carbon Equal 2 Inch Angle Steel Iron L Shape 250X250 Mild Steel Angle Bar

Carbon Equal Angle Steel, characterized by its symmetrical L-shaped cross-section and uniform leg lengths, is a critical structural component engineered for reliable load-bearing performance and structural stability across diverse industrial, construction, and infrastructure projects. This product line features a comprehensive range of premium carbon steel grades-including ASTM A36, ASTM A53, Q235, and Q345-and covers multiple standard dimensions such as 50X50X5 (leg length × leg length × thickness), 2 Inch, and 250X250. As mild steel-based angle bars, they combine excellent processability with cost-effectiveness, making them an ideal choice for framing, bracing, support structures, and various load-transmission applications.

From a material perspective, the selected grades adhere to global and national standards, tailored to meet varied performance requirements. ASTM A36, a widely recognized American standard carbon steel, boasts a minimum yield strength of 250 MPa and tensile strength of 400-550 MPa, offering exceptional ductility, weldability, and versatility for general structural use. ASTM A53, another American standard grade, is specifically optimized for piping and structural applications, featuring excellent formability and corrosion resistance in moderate environments. Q235, compliant with Chinese GB/T 700 standards, is a cost-effective mild carbon steel with a minimum yield strength of 235 MPa, suitable for light to medium-duty structural projects. Q345, a Chinese GB/T 1591 standard high-strength low-alloy steel, delivers a minimum yield strength of 345 MPa, providing enhanced load-bearing capacity and fatigue resistance for heavy-duty scenarios.

In terms of dimensional specifications and manufacturing, the product line covers diverse size needs to adapt to different project scales. The 50X50X5 and 2 Inch (equivalent to approximately 50.8X50.8 in metric) angle bars are ideal for light to medium load applications such as small-scale framing and pipe supports, while the 250X250 large-size angle bar is designed for heavy-duty structural components like high-rise building bracings and large-span bridge frameworks. All angle bars are typically produced via hot rolling, a process that heats steel billets above the recrystallization temperature to form a dense, uniform grain structure-enhancing mechanical stability, dimensional accuracy, and surface quality. Additionally, all grades exhibit excellent processability, allowing for easy cutting, drilling, welding, and forming; the mild steel base also enables flexible surface treatments (painting, galvanizing, powder coating) to improve corrosion resistance in harsh environments.

Regarding application scope and quality assurance, these carbon equal angle bars cater to global market demands. ASTM A36 and A53 grades are widely used in North American construction, industrial machinery bases, and piping support systems. Q235 and Q345 grades are staples in Chinese civil engineering, high-rise buildings, and heavy industry. The varied dimensions ensure (adaptability) from small residential projects to large-scale infrastructure. All products undergo rigorous quality control procedures, including material composition analysis, mechanical property testing (yield strength, tensile strength, impact toughness), and dimensional verification, ensuring compliance with respective standards. The combination of reliable material performance, precise dimensional control, and cost-effectiveness makes these angle bars a preferred structural solution for diverse end-use applications worldwide.
