This product is a premium hot rolled carbon mild steel equal angle bar, manufactured with Q235 grade carbon structural steel as the core raw material, a classic and widely applied general-purpose structural steel grade in global construction and manufacturing industries. Designed as an equal leg angle section, it features a standard 90-degree symmetrical L-shaped cross-section with identical side length and thickness across both legs, produced via sophisticated hot rolling technology to meet strict dimensional tolerances and mechanical property requirements. As a fundamental structural section steel, this Q235 equal angle bar combines stable performance, excellent processability and cost-effectiveness, serving as an indispensable material for a wide range of light to medium-duty engineering, construction and fabrication applications, with consistent quality and reliable load-bearing capacity to satisfy diverse industrial project demands.
Material Specification & Core Mechanical Properties
Q235 is a representative grade of ordinary carbon mild structural steel, where the letter "Q" stands for yield strength, and the numeral 235 indicates a minimum yield strength of 235 MPa, a key parameter that defines its stable load-bearing performance for general structural applications. This grade features a controlled low to moderate carbon content, with a well-balanced chemical composition free of excess harmful elements, ensuring exceptional ductility, toughness and plasticity while maintaining adequate structural strength. The minimum tensile strength of Q235 mild steel ranges from 375 to 500 MPa, delivering reliable resistance to compressive force, bending stress and shear force in routine working conditions.
Unlike high-alloy or high-strength steel grades, Q235 carbon mild steel does not require complicated pre-heat treatment or post-weld heat treatment under normal application scenarios, which greatly simplifies secondary processing and on-site construction procedures. Its uniform internal microstructure, achieved through refined smelting and rolling processes, eliminates common internal defects such as porosity, inclusions and micro-cracks, guaranteeing batch-to-batch consistency in mechanical properties and dimensional stability, fully complying with national and international structural steel quality standards.
Production Process & Product Structural Features
Our Q235 equal angle bars are fabricated through professional hot rolling technology, starting from high-quality continuous-cast steel billets that undergo strict raw material inspection to ensure initial material purity. The multi-pass hot rolling process shapes the billets into a precise L-shaped cross-section, followed by controlled cooling and high-precision straightening procedures, which are critical to ensuring product flatness, verticality and dimensional accuracy. Every production step adheres to standardized processing parameters, with strict monitoring of leg length, thickness, right-angle accuracy and overall straightness to meet international standard tolerances, avoiding deformation, size deviation or surface defects.
As an equal angle steel product, its symmetrical cross-sectional design ensures even stress distribution during application, effectively preventing uneven stress concentration and enhancing overall structural stability. The surface of the finished hot rolled angle bar is smooth and clean, with minimal oxide scale and no visible cracks, scratches or mechanical damages, making it suitable for direct use or further surface treatment such as anti-rust oil coating, painting or galvanizing based on specific application needs.
Key Processing & Application Advantages
