Hot Rolled Mild Carbon Steel Angle Iron 50x50x5mm S235JR Grade ASTM A36 Structural Steel
Angle steel is a fundamental structural component used to create various stress-bearing elements and serve as connectors between structural members. This versatile material finds extensive application across diverse construction and engineering projects including building frameworks, bridge construction, transmission towers, material handling equipment, shipbuilding, industrial furnace structures, reaction vessels, storage rack systems, and cable trench supports.
Available in two primary configurations:
- Equal Angle Steel: Both legs of identical dimensions
- Unequal Angle Steel: Available in equal thickness or varying thickness configurations

Angle steel is classified as carbon structural steel for construction applications. As a simple cross-section profile, it's primarily utilized for industrial building frameworks and structural supports. The material demonstrates excellent weldability, superior plastic deformation characteristics, and reliable mechanical strength. Production utilizes low-carbon steel billets, with final products delivered in hot-rolled, normalized, or as-rolled conditions to ensure optimal performance characteristics.
Our extensive inventory includes angle steel in sizes ranging from 2-20, categorized by edge length dimensions. Standard sizing employs centimeter measurements for side length designation. Each standard size typically offers 2-7 different thickness variations to accommodate diverse structural requirements.
Surface quality standards strictly prohibit structural defects that could compromise performance, including delamination, scarring, and cracking. Geometric tolerances are maintained within specified limits covering bending characteristics, dimensional accuracy, angular precision, and theoretical weight compliance.
Angle steel serves as fundamental building blocks for structural frameworks and connection systems across multiple industries. Applications span building construction, bridge engineering, transmission infrastructure, material handling equipment, marine construction, industrial processing facilities, and storage systems.
