Q195 Q235 Q275 S235jr S275jr Building Steel Structure H Beam C Beam Angle Steel

Our angle steel, compliant with Q195, Q235, Q275, S235jr, and S275jr standards, is a premium structural component tailored specifically for building steel structure applications. As a fundamental and versatile profile in construction engineering, this angle steel features a classic cross-sectional design with two mutually perpendicular legs (available in equal or unequal dimensions), which grants it exceptional structural rigidity, uniform load distribution capability, and remarkable ease of integration into various steel framing systems.

In terms of material credentials, the product covers a comprehensive range of authoritative carbon structural steel standards, both domestic and international, ensuring adaptability to diverse project requirements and regional specifications. The Chinese standard series (Q195, Q235, Q275) are well-recognized for their reliability in building structures: Q195 offers a yield strength of 195 MPa, making it suitable for light-duty structural components; Q235, a widely used grade, provides a yield strength of 235 MPa and excellent ductility, ideal for general-purpose building frames and supports; Q275 boasts a higher yield strength of 275 MPa, catering to heavy-duty structural demands that require enhanced load-bearing capacity. On the international front, the European standard grades S235jr and S275jr are engineered for structural applications, with minimum yield strengths of 235 MPa and 275 MPa respectively. The "jr" suffix indicates their compliance with room-temperature impact test requirements, ensuring superior toughness and resistance to brittle fracture, a critical attribute for building structures in varying environmental conditions.

Manufactured via advanced hot-rolling technology, our angle steel undergoes precise temperature control and rolling processes that optimize the steel's grain structure, thereby enhancing its mechanical properties such as tensile strength, fatigue resistance, and weldability. The product's surface is strictly inspected to eliminate defects like cracks, laminations, and excessive scale, ensuring a smooth and clean finish that not only improves corrosion resistance but also facilitates subsequent surface treatments (e.g., painting, galvanizing) for extended service life in harsh construction environments. A full spectrum of specifications is available, including various leg widths (ranging from 20mm to 200mm), leg thicknesses (3mm to 24mm), and lengths (6m to 12m or custom lengths), enabling seamless matching with different building design blueprints and structural load requirements.

A standout feature of this angle steel is its outstanding weldability and machinability, which are essential for efficient construction processes. It can be seamlessly joined using conventional welding techniques (e.g., shielded metal arc welding, gas metal arc welding, and submerged arc welding) without compromising structural integrity. Additionally, it supports easy machining operations such as cutting, drilling, bending, and punching, allowing for flexible fabrication into custom components like brackets, connectors, and reinforcing members. These properties significantly reduce on-site construction time and labor costs, making it a cost-effective solution for building projects.

Widely applicable in building steel structures, this angle steel serves as a core component in roof trusses, floor beams, wall frames, columns, and bracing systems for residential buildings, commercial complexes, industrial workshops, warehouses, and public infrastructure. Its compliance with multiple international and domestic standards ensures global applicability and compatibility with various construction materials and techniques. Throughout the production process, strict quality control measures are implemented, from raw material selection to final product inspection, guaranteeing that each batch of angle steel meets or exceeds the specified mechanical properties and dimensional accuracy requirements. This commitment to quality provides customers with the confidence that our angle steel will deliver long-term structural stability, safety, and performance for their building projects.
