Angel Steel Hot Rolled Carbon Steel 50*50*5 Q235 Q345c St235jr Grade Angle Iron ASTM Equal and Unequal Angle Steel

Our hot rolled carbon steel angle steel (also referred to as angle iron) is a high-quality structural product designed for diverse industrial and construction applications, featuring specific specifications, multiple premium material grades, and compliance with international standards. Available in both equal and unequal designs, this angle steel combines excellent mechanical performance, precise dimensional control, and reliable quality, making it a widely favored choice for various structural projects.

This angle steel is manufactured through advanced hot rolling technology, a mature process that ensures the product has a uniform cross-sectional structure, smooth surface finish, and tight dimensional tolerance. The hot rolling process involves heating carbon steel billets to a high temperature, followed by precision rolling to form the desired angular shape, which eliminates internal defects such as inclusions and cracks, while optimizing the material's internal grain structure. This enhances the angle steel's overall strength, ductility, and wear resistance, enabling it to withstand heavy loads, bending, and torsion in complex working environments.

We offer this hot rolled angle steel in a standard specification of 50*50*5 (leg length 50mm, thickness 5mm), which is a commonly used size in general structural applications. Meanwhile, we provide flexible options for both equal and unequal angle steel: equal angle steel (such as the 50*50*5 specification) features two legs of the same length, ensuring balanced load distribution and easy installation, suitable for building frameworks, scaffolding, and decorative structures; unequal angle steel, with two legs of different lengths, offers flexible load-bearing solutions for special structural designs, mechanical manufacturing, and bridge accessories.

The angle steel is available in multiple high-quality carbon steel grades, including Q235, Q345C, and St235JR, each tailored to different performance requirements and application scenarios, and complies with ASTM standards to meet international quality benchmarks. Q235 is a widely used mild carbon steel, boasting good weldability, machinability, and cost-effectiveness, suitable for general structural projects. Q345C, a low alloy carbon steel grade, offers higher strength and excellent low-temperature toughness, making it ideal for outdoor, high-humidity, or low-temperature environments such as bridge engineering and offshore structures. St235JR, a European standard carbon steel, features stable mechanical properties and reliable quality, widely applied in machinery manufacturing and industrial equipment.

Crafted from high-purity carbon steel raw materials, our angle iron undergoes strict quality control throughout the entire production process-from raw material inspection to finished product testing-to ensure each batch meets the specified grade requirements and ASTM standards. The product maintains good weldability and machinability, allowing for easy cutting, drilling, and welding during installation, which improves construction efficiency and reduces project costs.

With its precise specification, diverse material grades, compliance with international standards, and excellent mechanical performance, our hot rolled carbon steel angle steel is widely used in construction, machinery manufacturing, bridge engineering, scaffolding, container production, and other fields. It provides stable and durable structural support for both general and special projects, balancing performance and cost-effectiveness to meet the diverse needs of global customers.
