Hot Rolled Carbon Steel Angle Bar Ss400 Q235 High Quality Mild Carbon Angle Steel

Our hot-rolled carbon steel angle bars, available in SS400 and Q235 grades, represent high-quality mild carbon steel products engineered for superior performance and versatility in structural and industrial applications. As a fundamental type of section steel with a right-angle cross-sectional profile, this angle bar is manufactured through advanced hot-rolling processes, which endow it with exceptional mechanical properties and structural integrity.

The SS400 and Q235 grades are widely recognized mild carbon steel specifications, characterized by optimal carbon content that balances strength, ductility, and weldability. SS400, a Japanese industrial standard grade, boasts a minimum yield strength of 400 MPa, making it suitable for load-bearing structural components. Q235, adhering to Chinese national standards, features a yield strength of 235 MPa and exhibits excellent formability, enabling easy cutting, bending, and machining to meet diverse custom requirements. Both grades offer good corrosion resistance in dry environments and can be further enhanced with protective coatings such as galvanization for harsh working conditions.

The hot-rolling production process is a key factor contributing to the superior quality of these angle bars. During hot rolling, the steel billet is heated to high temperatures (typically above 1000°C) and then passed through a series of rolling mills to form the desired angular cross-section. This process refines the grain structure of the steel, improving its toughness and tensile strength while ensuring uniform dimensional accuracy across the entire length of the product. The resulting angle bars have a smooth surface finish, free from significant defects, and maintain consistent mechanical properties, which is critical for reliable structural performance.

These high-quality mild carbon angle bars find extensive application in various industries, including construction, machinery manufacturing, automotive, and infrastructure development. In the construction sector, they are commonly used as framing members, bracing, supports, and reinforcements in buildings, bridges, warehouses, and power transmission towers. In machinery manufacturing, they serve as components in equipment frames, brackets, and conveyor systems. Additionally, their excellent weldability and formability make them ideal for fabricating custom structures and components tailored to specific project needs.

We are committed to upholding the highest quality standards in the production of our SS400 and Q235 hot-rolled carbon steel angle bars. Each batch of products undergoes rigorous quality inspection, including chemical composition analysis, mechanical property testing, and dimensional verification, to ensure compliance with international and national standards. Our angle bars are available in a wide range of sizes (in terms of leg length, thickness, and length) to accommodate the diverse requirements of different applications, providing customers with reliable and cost-effective solutions for their structural and industrial needs.
