AISI Q235B Standard Packing Model Number: Ss400 Carbon Unqual Angle Steel

Our AISI Q235B Ss400 carbon unequal angle steel stands out as a high-performance structural component, designed to meet the diverse demands of industrial engineering and construction. Distinguished by its unequal leg cross-section, compliance with AISI standards, and alignment with Ss400 material specifications, this angle steel combines exceptional mechanical strength, dimensional accuracy, and convenient standard packing-making it a reliable choice for projects requiring tailored load-bearing solutions and efficient logistics management.

Core Material & Standard Compliance: A Fusion of Performance and Reliability

At the heart of this product lies a dual commitment to material excellence and global standards:

AISI Q235B Certification: Adhering to the American Iron and Steel Institute (AISI) guidelines, Q235B is a low-carbon structural steel grade renowned for its balanced properties. It boasts a minimum yield strength of 235 MPa and a tensile strength range of 375–500 MPa, with an elongation rate of ≥26%-ensuring superior ductility for on-site forming (e.g., bending, cutting) without compromising structural integrity. The "B" suffix indicates its ability to pass impact tests at 20°C, making it suitable for use in moderate-temperature environments, from indoor factories to outdoor infrastructure.

Ss400 Material Alignment: Complementary to AISI Q235B, the product aligns with Japan's JIS G3101 Ss400 standards-a widely adopted carbon steel grade with a minimum yield strength of 245 MPa and tensile strength of 400–510 MPa. Ss400 enhances the angle steel's machinability and weldability, allowing seamless integration with other steel components via arc welding, gas metal arc welding (GMAW), or bolting. This dual compliance ensures compatibility with both North American and Asian industrial norms, facilitating cross-border projects and global supply chains.

Unequal Angle Design: Tailored for Targeted Load Distribution

Unlike equal-angle steel, the unequal leg profile of this product is engineered to address specific load-bearing challenges. The asymmetrical leg lengths (e.g., common configurations like 50×30×5mm, 75×50×6mm, or custom sizes) allow for optimized stress distribution: the longer leg provides enhanced vertical load support, while the shorter leg offers stability for horizontal bracing or attachment to narrower surfaces. This design is particularly valuable in applications where space constraints or uneven load requirements demand a non-uniform structural solution-such as in machinery frames, conveyor supports, or architectural trusses where one side bears greater weight than the other.

Manufactured via precision hot-rolling (conducted at temperatures exceeding 1,050°C), the unequal angle steel features a dense, homogeneous grain structure. This process eliminates internal defects, enhances surface smoothness, and ensures tight dimensional tolerances (consistent with AISI and JIS standards for leg length, thickness, and squareness). The hot-rolled finish also improves the material's resistance to fatigue and deformation, even under repeated or dynamic loads-critical for long-term industrial performance.

Standard Packing: Efficiency in Storage, Transport, and Handling

Recognizing the importance of logistics in industrial operations, our AISI Q235B Ss400 unequal angle steel is supplied in standard packing that prioritizes protection, space efficiency, and ease of handling:

Packaging Configuration: Each batch is bundled into uniform packs, with angle steel pieces aligned and secured using high-tensile steel straps (25mm–30mm width) to prevent shifting during transport. The number of pieces per pack is standardized based on leg size (e.g., 50 pieces per pack for smaller profiles, 20–30 pieces for larger sizes) to ensure consistent weight (typically 500kg–1,000kg per pack) and compatibility with forklifts or hoists.

Protective Measures: To guard against corrosion and surface damage, each pack is wrapped in a moisture-resistant polyethylene (PE) film, with additional cardboard or foam padding at the edges to prevent dents during loading/unloading. For long-term storage or marine transport, optional galvanized steel sheets can be added as outer layers to enhance resistance to saltwater and humidity.

Labeling & Traceability: Every pack is clearly labeled with critical information, including material grade (AISI Q235B/Ss400), leg dimensions (e.g., "75×50×6mm"), length (6m/12m), batch number, manufacturing date, and compliance certificates (AISI, JIS). This labeling ensures easy inventory management, quick identification of specifications, and full traceability for quality control purposes.

Key Advantages & Industrial Applications

This carbon unequal angle steel offers a suite of benefits that cater to industrial needs:

Targeted Load Support: The unequal leg design delivers precise load distribution, making it ideal for projects with asymmetric stress requirements.

Broad Compatibility: Dual compliance with AISI Q235B and Ss400 standards ensures integration with global manufacturing processes and construction codes.

Durability: Hot-rolled construction and low-carbon composition enhance resistance to wear, fatigue, and environmental damage (when paired with optional coatings like galvanization or epoxy).

Logistical Efficiency: Standard packing reduces storage space requirements, minimizes transport costs, and simplifies on-site handling-accelerating project timelines.

Its applications span across industries:

Mechanical Engineering: Used as supports for machinery frames, gearboxes, and conveyor systems, where unequal legs accommodate irregular component sizes.

Construction & Infrastructure: Employed in building facades, roof trusses, and bridge bracings, where asymmetric loads demand tailored structural solutions.

Manufacturing & Fabrication: Integrated into storage racks, industrial workbenches, and material handling equipment, leveraging its machinability for custom modifications.

Automotive & Heavy Equipment: Utilized as reinforcement in vehicle chassis, trailer frames, and agricultural machinery, where strength and dimensional precision are critical.

Quality Assurance

Every batch of AISI Q235B Ss400 unequal angle steel undergoes rigorous quality testing: raw material analysis (to verify carbon content and alloy composition), mechanical property testing (yield strength, tensile strength, impact resistance), dimensional inspection (leg length, thickness, squareness), and surface quality checks (no cracks, burrs, or rust). Each pack is accompanied by a Certificate of Conformance (CoC), ensuring compliance with AISI and JIS standards and providing customers with confidence in product performance.

For industrial professionals seeking a versatile, standards-compliant, and logistically efficient structural solution, our AISI Q235B Ss400 carbon unequal angle steel-with its precision unequal leg design and standard packing-delivers the reliability and functionality needed to drive project success.
