Manufacture Angel Steel Hot Rolled Mild Carbon Steel 50*50*5 S235jr Grade Angle Iron ASTM A36 Equal and Unequal Angle Steel Factory Price

Our hot rolled mild carbon steel angle steel, available in both equal and unequal leg configurations, complies with international standards including S235jr and ASTM A36, with the 50×50×5mm equal angle as a flagship specification. As a core product in structural steel profiles, this angle steel (also referred to as angle iron) features a robust L-shaped cross-section, engineered to deliver exceptional load-bearing capacity, structural stability, and durability. Crafted exclusively from high-quality mild carbon steel via advanced hot rolling processes, it is tailored for diverse industrial and construction applications, offering a reliable and cost-effective solution at factory-direct prices.

The product is built on two globally recognized material standards, ensuring consistent performance and broad applicability. S235jr, a European standard mild carbon structural steel, boasts a minimum yield strength of 235 MPa and a tensile strength range of 360-510 MPa. The "jr" suffix confirms its compliance with room-temperature impact testing requirements, guaranteeing excellent toughness and resistance to brittle fracture-critical attributes for structural safety. ASTM A36, a widely adopted international standard, offers a minimum yield strength of 250 MPa and tensile strength of 400-550 MPa, renowned for superior ductility and weldability. Both standards are aligned with mild carbon steel's inherent properties, ensuring the angle steel balances strength and workability while maintaining cost-effectiveness, making it suitable for general and heavy-duty structural applications alike.

Manufactured through a precision hot rolling process, the angle steel undergoes strict temperature control-with steel billets heated above the recrystallization temperature before rolling. This process refines the steel's grain structure, enhancing its mechanical properties such as toughness, impact resistance, and fatigue strength. The 50×50×5mm equal angle specification (50mm equal legs, 5mm thickness) is a highly versatile option, featuring optimized dimensions for balanced stress distribution. Hot rolling imparts a characteristic slightly scaled surface, which is easily treatable and ideal for heavy-duty structural components where strength and cost-efficiency are prioritized. All products undergo rigorous quality inspections, including chemical composition analysis, mechanical property testing, dimensional accuracy verification, and surface defect checks, ensuring each batch meets or exceeds standard requirements.

Both equal and unequal leg configurations cater to specialized structural needs. Equal angle steel (such as the 50×50×5mm variant) ensures uniform load distribution across its symmetric cross-section, making it ideal for frames, trusses, bracing systems, connecting brackets, and general structural reinforcement. Unequal angle steel, with one leg longer than the other, provides enhanced rigidity in a specific direction, suitable for edge reinforcement, beam flanges, and asymmetric load-bearing scenarios (e.g., industrial equipment frames, infrastructure supports). A key advantage of this mild carbon steel angle iron is its exceptional weldability and machinability, compatible with conventional welding techniques (shielded metal arc welding, gas metal arc welding, submerged arc welding) and machining processes (cutting, drilling, bending). This versatility allows for flexible fabrication into custom components, reducing on-site construction time and labor costs.

Our hot rolled mild carbon steel angle steel (S235jr/ASTM A36) is widely applied across industries, including building construction (residential complexes, commercial malls, industrial warehouses), infrastructure (bridges, railways, highway guardrails), mechanical manufacturing (equipment frames, brackets, conveyor systems), and architectural engineering (curtain wall supports, decorative structures). The 50×50×5mm equal angle, in particular, is a popular choice for medium-duty structural applications due to its balanced dimensions and reliable performance. Offered at factory-direct prices, the product delivers exceptional value without compromising quality. Backed by strict quality assurance systems and compliance with international standards, our angle steel ensures long-term structural stability, safety, and durability, making it a preferred choice for both domestic and international projects requiring high-quality, cost-effective structural steel profiles.
