This product is a premium hot-rolled equal carbon steel angle bar with a standard specification of 50mm × 50mm, manufactured from high-grade S235 carbon structural steel, a widely recognized and universally applied general-purpose structural steel grade complying with European standard EN 10025-2. Engineered with a precise 90-degree symmetrical L-shaped cross-section and equal leg dimensions, this angle bar is produced via advanced hot-rolling processes to deliver consistent mechanical properties, strict dimensional accuracy and exceptional structural stability. Tailored specifically for bulk procurement demands, it combines reliable quality, cost-efficiency and consistent batch performance, serving as an ideal structural material for large-scale construction projects, industrial manufacturing, steel structure fabrication and routine engineering applications with high-volume material requirements.
Material Grade Overview & Core Mechanical Properties
S235 carbon steel is a non-alloy general structural steel grade, where the numeral 235 denotes a minimum yield strength of 235 MPa, matching the performance benchmark of mainstream general carbon structural steels and ensuring stable load-bearing capacity for light to medium-duty engineering scenarios. This grade features a controlled moderate carbon content and balanced chemical composition, free of excessive harmful impurities, which endows it with outstanding ductility, toughness and plasticity, alongside reliable resistance to compression, bending and shear forces under normal working conditions. The tensile strength of S235 carbon steel ranges from 360 to 510 MPa, with stable mechanical indicators that meet international structural steel standards, eliminating performance fluctuations between batches.
Distinguished by its excellent processing adaptability, S235 carbon steel requires no complex pre-weld heating or post-weld heat treatment in conventional application environments, greatly simplifying on-site cutting, welding, bending and drilling operations. Its refined internal microstructure, formed through professional smelting and hot-rolling processes, effectively eliminates internal defects such as porosity, inclusions and micro-cracks, ensuring long-term structural stability and consistent quality-critical attributes for bulk purchase projects that demand uniform material performance across large quantities.
Fixed Specification: 50X50mm Equal Angle Bar
This product adopts a standard 50mm × 50mm equal leg specification, a universally versatile size extensively used in global engineering and construction sectors, with strictly controlled leg length, thickness and right-angle accuracy to meet international tolerance standards. The uniform 50mm leg dimension ensures symmetrical stress distribution, preventing uneven stress concentration and enhancing overall load-bearing efficiency; the standardized thickness guarantees adequate structural strength without unnecessary material waste, striking an optimal balance between performance and cost. This fixed specification is highly compatible with bulk production, storage and transportation, reducing procurement complexity and ensuring fast, stable supply for large-volume orders, making it the top choice for bulk purchasing customers with standardized project requirements.
Production Process & Quality Features
Our S235 50×50mm carbon steel angle bars are fabricated through industrial-grade hot-rolling technology, starting from high-quality continuous-cast steel billets that pass rigorous raw material inspection to ensure initial material purity. The multi-pass hot-rolling process shapes the billets into a precise L-shaped profile, followed by controlled cooling and high-precision straightening to maintain perfect flatness, verticality and dimensional consistency. The finished product features a smooth, clean surface with minimal oxide scale, no visible cracks, scratches or mechanical damages, and uniform cross-section throughout the entire length, complying with strict quality inspection criteria for bulk supply.
Every batch of products undergoes comprehensive quality testing, including chemical composition analysis, mechanical property verification and dimensional accuracy measurement, to ensure full compliance with EN 10025-2 standards. For bulk purchase orders, we implement strict batch tracking and quality consistency control, ensuring that every piece of angle bar in the entire order maintains uniform performance and specifications, avoiding quality deviations that may affect project construction progress.
