Hot rolled steel angle, commonly referred to as angle iron, is a fundamental structural steel component characterized by its L-shaped cross-section, which is formed by two mutually perpendicular legs of equal length (equal angle steel)[2
The hot rolling process, a core manufacturing technique for this product, involves heating steel billets to temperatures exceeding 1100°C to ensure optimal plasticity, followed by precision rolling to form the distinctive L-shaped profile[
The material grades featured in this product line are carefully selected to cater to different performance demands. A36, an American standard carbon structural steel, boasts a minimum yield strength of 250 MPa and excellent formability, making it suitable for general structural applications such as building frames, bridges, and machinery supports[
The specified dimensions of 100X100X6 and 160X160X6 represent two commonly used equal leg hot rolled steel angles. The 100X100X6 angle features 100mm equal legs with a 6mm thickness, providing reliable rigidity for medium-load structural connections, while the 160X160X10 angle, with 160mm equal legs and a 10mm thickness, offers enhanced load-bearing capacity for heavy-duty frameworks, transmission towers, and industrial equipment supports
As a versatile structural component, hot rolled steel angles are widely applied in various fields, including building construction, bridge engineering, power transmission, machinery manufacturing, and warehouse shelving[2[
All products in this line adhere to strict quality control standards, with comprehensive testing of chemical composition, mechanical properties, and geometric accuracy to ensure compliance with global industry specifications. The combination of premium materials, advanced hot rolling technology, and standardized dimensions makes these hot rolled steel angles a reliable choice for engineers and contractors seeking high-performance, cost-effective structural solutions.
