45# Unequal Angle Steel

Commonly used in machinery frames, support brackets, heavy-duty racks, and reinforcement structures, our 45# unequal angle steel provides a durable and cost-effective solution for medium-to-high stress applications. We offer tailored processing, including precise cutting and surface treatment, along with certified material documentation for quality assurance.

We provide 45# carbon steel unequal angle bars, hot-rolled from high-quality medium-carbon steel to deliver superior mechanical strength and reliable load-bearing performance. Characterized by its unequal leg design, this angle type offers optimized support solutions where asymmetrical force distribution or specific spatial constraints are required, making it ideal for industrial and structural applications that demand higher strength than standard mild steel angles.

Product Highlights:

  • Enhanced Mechanical Properties: With a carbon content of approximately 0.45%, it provides higher tensile strength and hardness compared to common low-carbon steel angles.

  • Versatile Asymmetric Design: Ideal for applications requiring differentiated load transfer, such as bracket systems, reinforced edges, and specialized structural connections.

  • Reliable Machinability: Can be easily cut, drilled, and welded, offering adaptability for customized fabrication and assembly.

  • Quality Consistency: Produced under controlled rolling conditions to ensure uniform material properties and dimensional accuracy.

  • Broad Specification Range: Available in various unequal leg combinations, with thickness and length customization to meet project requirements.

Our high-strength angle steel is manufactured from premium quality steel materials, available in both equal and unequal leg specifications. The hot-rolling process ensures excellent mechanical properties and straightness, making it widely used in structural applications such as building frames, supports, and equipment bases. Customization in length, punching, and surface treatment is supported.





Our angle steel is manufactured through fully automated hot-rolling production lines, equipped with precision roll-forming systems and multi-pass straightening processes to ensure dimensional accuracy (leg thickness tolerance ±0.3mm, length tolerance ±5mm) and straightness (≤1mm/m). The production line integrates online laser rangefinders, real-time mechanical property testing, and surface quality monitoring systems. Compliant with ASTM, JIS, EN, and other international standards, we support custom non-standard sizes and materials (e.g., Q235B, Q355B, SS400), making our products widely used in building structures, machinery manufacturing, and power engineering applications.





In order to ensure product quality, we will arrange professional personnel to check product quality, packaging, weight, hardness, etc., according to customer requirements of product specifications, looking for high-quality and cheap cooperative factories in China, to provide customers with one-stop procurement services and quality assurance.





Excellent packaging: waterproof paper and plastic film + iron cover + at least three strapping straps + strapping straps fixed on iron or wood pallets can effectively protect products from corrosion and various climate changes during transportation. Generally speaking, we ship from Shanghai, Tianjin, Qingdao and Ningbo ports. We have worked with many experienced shipping companies for a long time to find the most suitable mode of transportation for you.
