Angle steel is a strip-shaped metal material with an L-shaped cross-section, typically manufactured through hot-rolling, cold-drawing, or forging processes. Due to its cross-sectional form, it is also referred to as “L-shaped steel” or “angle iron.” This material is widely used in various construction and engineering structures owing to its robust structure and ease of connection.
Core Characteristics
Strong Structural Stability: The L-shaped cross-section provides excellent load-bearing capacity and structural integrity, making it highly adaptable across diverse structural applications and a common choice for structural support.
Broad Functional Compatibility: Serves as a core component in beams, bridges, towers, and various support structures, meeting the diverse structural requirements of different engineering projects.
High Processability: Easy to cut, weld, and install, facilitating efficient construction and manufacturing operations while boosting productivity.
Cost-Effectiveness: Compared to other structural steels, angle steel production involves relatively simplified processes. This results in overall cost advantages while maintaining performance, offering outstanding value for money.
Specifications and Models
Angle steel specifications are typically denoted as “leg length × leg length × leg thickness.” Equal-leg angle steel features identical leg lengths on both sides, while unequal-leg angle steel has differing leg lengths. For example, “50×36×3” denotes an unequal-leg angle steel with leg lengths of 50mm and 36mm, respectively, and a leg thickness of 3mm. Equal-leg angle steel offers a wide range of specifications, requiring selection based on project requirements. Currently, equal-leg angle steels with leg lengths of 50mm and 63mm are most widely used in engineering applications.

2)Unequal Angle bar Size Range(25*16*3*4~ 200*125*18*14)
Production Processes
Hot-Rolling Process: The predominant production method for angle steel. Steel billets are rolled into an L-shaped cross-section at high temperatures using rolling mills. This process is suitable for mass production of standard-sized angle steel, offering mature technology and high efficiency.
Cold Drawing Process: Suitable for scenarios requiring high precision, this process produces angle steel with tighter dimensional tolerances and superior surface quality. Conducted at room temperature, it further enhances the mechanical strength of the angle steel.
Forging Process: Primarily used for producing large-sized or special-performance angle steel. Forging optimizes the material's grain structure, improving overall mechanical properties to meet customized component requirements for specialized engineering projects.
Application Fields
Construction Industry: Serves as structural components such as support beams, frames, and frameworks, providing stable structural support for buildings.
Manufacturing: Used for warehouse shelving, production workbenches, and machine supports. Its structural strength and machinability adapt to diverse production and storage facility requirements.
Bridge Construction: Acts as a critical structural support component, ensuring stability and safety during bridge operation.
Decorative Applications: Leveraging its structural integrity and aesthetic properties, it serves in interior and exterior design projects, balancing functionality with visual appeal.
Shipbuilding: Suitable for fabricating internal frameworks and supports in vessels, it meets the unique demands of maritime environments, ensuring structural reliability.
