GB JIS Steel Angle ASTM A588/A588m Q235B 50X50X5, S235jr 100X100X10, A36 4X4X1/4

Our carbon steel angle steel series encompasses a comprehensive range of material grades and specifications, including GB Q235B, JIS standard grades, ASTM A588/A588M, EN S235JR, and ASTM A36, with key dimensions such as 50×50×5mm, 100×100×10mm, and A36 4×4×1/4 inch. As essential structural components, these hot-rolled angle steels are engineered to deliver superior mechanical performance and structural reliability, catering to diverse industrial, commercial, and construction applications that demand robust load-bearing and bracing capabilities.

In terms of material properties, each grade within this series is tailored to meet specific industry standards and performance requirements. ASTM A588/A588M, a weathering steel grade, exhibits exceptional corrosion resistance in atmospheric environments, eliminating the need for additional painting in many applications and reducing long-term maintenance costs. GB Q235B and EN S235JR, as widely used carbon structural steel grades, offer balanced tensile strength (minimum 370 MPa for Q235B, 360 MPa for S235JR) and yield strength (minimum 235 MPa for both), ensuring excellent ductility and weldability for easy fabrication. ASTM A36, a versatile carbon steel grade, features a minimum tensile strength of 400 MPa and yield strength of 250 MPa, making it suitable for general structural purposes. All grades undergo advanced hot-rolling processes, which refine the internal grain structure, enhance toughness, and reduce brittleness-critical attributes for maintaining structural integrity under cyclic loads and harsh operating conditions.

The diverse specifications of this angle steel series are meticulously calibrated to address varying load and structural demands. The 50×50×5mm angle steel, with its balanced leg length and thickness, is ideal for light to medium-duty applications such as small-scale framework, shelf supports, and bracing. The 100×100×10mm heavy-duty variant offers enhanced structural rigidity and load-bearing capacity, suitable for large industrial frameworks, bridge components, and heavy equipment supports. The A36 4×4×1/4 inch (101.6×101.6×6.35mm) specification, compliant with imperial standards, caters to international projects requiring precise dimensional compatibility. All equal-angle designs ensure uniform stress distribution across both legs, enabling effective resistance to vertical compression and lateral shear forces. The natural hot-rolled surface finish provides a foundation for optional surface treatments (e.g., galvanizing, powder coating, or painting) to further improve corrosion resistance, adapting to environments such as warehouses, construction sites, ports, and manufacturing facilities.

Beyond their core structural applications, this multi-grade, multi-specification carbon steel angle steel series offers exceptional versatility. They are widely utilized in framework fabrication, building reinforcements, machinery bases, shipping containers, and infrastructure projects. Adherence to international and regional standards (GB, JIS, ASTM, EN) guarantees consistent quality control, material traceability, and performance reliability across all product variants. Whether for domestic construction projects requiring Q235B grade, weather-resistant applications needing ASTM A588/A588M, or general structural tasks utilizing A36 or S235JR, this angle steel series provides cost-effective, durable solutions tailored to meet the unique requirements of each project.
