Classification of Angles
Steel Angle, also known as Angle Iron or L-Bar, is a hot-rolled carbon structural steel characterized by its L-shaped cross-section with a 90-degree internal angle.

It is the most fundamental and versatile structural component used in modern construction, telecommunications, and daily manufacturing.
As a leading China manufacturer, we offer both Equal Angle (same leg lengths) and Unequal Angle (different leg lengths) bars, available in various grades such as S275JR, S235JR, A36, and Q235B, with surface treatments including Hot-Dip Galvanizing (HDG) for maximum corrosion resistance.
Technical Specifications & Material Grades of Steel Angle
We provide a wide range of steel grades to meet different international project requirements.
A. Popular Material Comparison
| Standard | Grade | Yield Strength (min) | Tensile Strength | Feature |
| EN 10025 | S275JR | 275 MPa | 410-560 MPa | Best balance of strength & weldability |
| EN 10025 | S235JR | 235 MPa | 360-510 MPa | Most cost-effective, high ductility |
| ASTM | A36 | 250 MPa | 400-550 MPa | US standard, versatile |
| JIS | SS400 | 245 MPa | 400-510 MPa | Common in Asian engineering |
| GB/T | Q235B/Q355B | 235/355 MPa | 370-630 MPa | High availability, structural grade |
B. Size Range (Bespoke Sizes Available)
| Type | Leg Size (mm) | Thickness (mm) | Standard Length |
| Equal Angle | 20x20mm - 250x250mm | 3mm - 25mm | 6m, 9m, 12m or Cut-to-length |
| Unequal Angle | 45x30mm - 200x150mm | 3mm - 18mm | 6m, 9m, 12m or Cut-to-length |
Key Mechanical & Chemical Properties of Steel Angle
For high-load structural applications, our S275JR Angle Steel is the top choice.
- Chemical Balance: Carbon (≤0.21%) and Manganese (1.50%) ensure excellent weldability and toughness.
- Impact Strength: Tested at 27J at +20°C, ensuring reliability in varied climates.
- Formability: Can be easily bent and punched without cracking (Bend Radius: 1.5t).
Surface Treatment Options of Steel Angle
To ensure long-lasting performance in aggressive environments, we offer three primary finishes:
- Black (Self-Color): Best for indoor use or components that will be painted later.
- Hot-Dip Galvanized (HDG): Coated with a thick layer of zinc (min. 65μm). Best for coastal and outdoor cable towers.
- Pre-Painted/Primed: Available in various colors (Black, Grey, Red) for immediate aesthetic application.
Extensive Applications of Steel Angle
Our Angle Bars are the "backbone" of industrial and residential projects:
- Infrastructure: Cable & transmission towers (Black or Galvanized), bridge reinforcements, and highway railings.
- Warehouse Solutions: High-load shelving systems, mezzanine frames, and storage racks.
- Building Construction: Roof trusses, lintels, door/window frames, and reinforced concrete structures.
- Daily Life: Bed frames, AC support brackets, fencing posts, and bespoke furniture (coffee tables, benches).
