Introduction to Angle Steel (Angle Bar)

Angle steel, commonly referred to as angle bar, is a fundamental hot-rolled or welded structural steel product distinguished by its distinctive L-shaped cross-section. Comprising two perpendicular "legs" (either equal or unequal in length) joined at a right angle, this design balances structural rigidity, connectivity, and material efficiency—making it an indispensable component in construction, infrastructure, and industrial manufacturing globally.

Dimensional Specifications & Steel Grades

1. Dimensional Expression

Angle steel dimensions are universally specified in millimeters (mm) using a clear format:

Equal-Leg: Leg Length × Leg Length × Leg Thickness (e.g., 63×63×5, 100×100×8)

Unequal-Leg: Longer Leg × Shorter Leg × Leg Thickness (e.g., 125×80×10, 200×125×12)

Common leg lengths range from 20mm to 200mm, with thicknesses from 3mm to 20mm. Standard lengths are 6m, 9m, or 12m, though custom cutting is available for project-specific needs.

2. Common Steel Grades

The base material adheres to global structural steel standards, with grades selected based on load requirements, environment, and weldability:
