This series of angle bar covers two mainstream structural steel grades, ASTM A36 and European standard S235JR, and is available in both equal side and unequal side L-shaped cross sections to accommodate diverse structural design and load-bearing requirements in global engineering projects. Manufactured from premium carbon iron steel, the product complies with internationally recognized technical specifications for rolled structural profiles, ensuring stable metallurgical performance and reliable dimensional consistency across applications.
ASTM A36 is a widely adopted carbon structural steel featuring well-controlled chemical composition, excellent ductility, and universal weldability. It delivers a minimum yield strength of 250 MPa and a tensile strength ranging from 400 MPa to 550 MPa, providing dependable performance for general building frames, bracing components, and conventional load-bearing structures. S235JR, conforming to EN 10025-2 standards, is a non-alloy structural carbon steel with guaranteed room-temperature impact toughness marked by the JR grade. With a minimum yield strength of 235 MPa and balanced tensile properties, it exhibits outstanding formability and compatibility, making it highly suitable for European standard construction, mechanical fabrication, and infrastructure assembly.
Supplied in both equal and unequal configurations, the angle steel features a typical L-shaped profile with uniform wall thickness. Equal side angle bar maintains symmetrical leg dimensions for even force distribution, ideal for regular frame connection and vertical supporting structures. Unequal side angle bar adopts two different leg lengths, enabling flexible force transmission and adaptive installation for irregular structural joints, wall brackets, equipment bases, and asymmetric load scenarios.
Produced through professional hot rolling processes, the material internal grain structure is refined to eliminate inherent defects such as pores, inclusions and microcracks, further enhancing overall toughness, compression resistance and structural stability. The raw iron steel base allows convenient secondary processing including cutting, drilling, bending and welding, without causing brittleness or structural damage during fabrication.
Widely applied in architectural construction, industrial manufacturing, municipal infrastructure and mechanical supporting systems, this A36 and S235JR combined angle steel series meets cross-regional standard demands. Each batch undergoes strict inspection on chemical composition, mechanical properties and dimensional accuracy to ensure long-term service stability. It serves as a fundamental, cost-effective and highly versatile structural material for modern global engineering projects.
