Hot Rolled ASTM 100X100 S235jr S275jr S355jr Ss400 Angle Steel

Material Specifications & Mechanical Properties​

The product adheres to stringent international standards, with each material grade offering distinct performance attributes to suit varied load-bearing requirements:​

S235jr: A non-alloy structural steel grade compliant with EN 10025-2, featuring a minimum yield strength of 235 MPa. It exhibits excellent weldability, formability, and ductility, making it ideal for general structural frameworks and non-critical load applications.​

S275jr: With a minimum yield strength of 275 MPa, this grade delivers enhanced tensile strength and load-bearing capacity compared to S235jr. It maintains good weldability and is widely used in medium-duty structural components, such as building columns, beams, and bracing systems.​

S355jr: A high-strength non-alloy steel grade (EN 10025-2) with a minimum yield strength of 355 MPa. Renowned for its superior toughness, fatigue resistance, and machinability, it is suitable for heavy-duty structures, industrial machinery, and offshore applications where durability under high stress is paramount.​

SS400: A Japanese industrial standard (JIS G 3101) structural steel grade, equivalent to ASTM A36, with a minimum yield strength of 235 MPa (and higher tensile strength ranges). It is a versatile, cost-effective option for general construction, fabrication, and infrastructure projects.​

All grades undergo rigorous quality control measures, including chemical composition analysis, tensile testing, and dimensional inspection, to ensure compliance with ASTM and relevant international standards. The hot rolling process eliminates internal defects, enhances grain structure, and imparts excellent surface finish, reducing the need for additional processing.​

Structural Advantages & Applications​

The 100X100 equal leg design provides balanced load distribution across both legs, enabling efficient transfer of axial, bending, and shear forces. This structural efficiency makes the angle steel a preferred choice for:​

Building frames, trusses, and roof structures in commercial, industrial, and residential construction.​

Fabrication of storage racks, shelves, and material handling equipment.​

Infrastructure projects such as bridges, highways, and railway components.​

Industrial machinery bases, supports, and bracing systems.​

Marine and offshore structures (particularly S355jr grade for its corrosion resistance and strength).​

Additionally, the material's weldability allows for easy integration into complex assemblies, while its formability supports bending, cutting, and drilling to meet custom design requirements.​

Quality Assurance & Compliance​

Our hot rolled angle steel is produced in ISO-certified facilities, adhering to strict environmental and safety standards. Each batch is accompanied by a certificate of conformity (CoC), verifying material grade, mechanical properties, and compliance with ASTM A36 (for SS400 equivalent) and EN 10025 (for S235jr/S275jr/S355jr) specifications. We ensure consistent supply, reliable performance, and technical support to meet the diverse needs of global customers.
