What is Angle Iron?
Angle iron, despite its name, is not always made of iron. It’s a structural steel shape formed into a 90-degree angle with equal or unequal legs. This L-shaped cross-section provides excellent strength characteristics while remaining cost-effective and versatile.
Material Properties
- Material: Hot-rolled mild steel (ASTM A36 most common)
- Yield Strength: 36,000 PSI minimum
- Tensile Strength: 58,000-80,000 PSI
- Density: 0.2833 lb/in³ (7.85 g/cm³)
Understanding Angle Iron Sizes
Size Designation
Angle iron is specified by three measurements:
- Leg Width × Height × Thickness (Example: 2″ × 2″ × ¼”)
- Equal Legs: Both legs same length (most common)
- Unequal Legs: Different leg lengths for specific applications
Most Common Commercial Sizes
| Size (inches) | Weight (lb/ft) | Cross Section (in²) | Typical Applications |
|---|---|---|---|
| 1½ × 1½ × ⅛ | 1.23 | 0.36 | Light duty brackets, small supports |
| 2 × 2 × ¼ | 3.19 | 0.94 | Medium frames, supports, bracing |
| 3 × 3 × ¼ | 4.85 | 1.44 | Heavy construction, main supports |
| 4 × 4 × ⅜ | 9.80 | 2.89 | Major structural elements |

Technical Considerations
Load Bearing Capacity
Load capacity depends on:
- Size and thickness
- Span length
- Loading direction
- Support conditions
Always consult structural tables or an engineer for specific load requirements.
Working with Angle Iron
- Cutting: Band saw, cold saw, or abrasive wheel
- Drilling: Use cutting fluid, proper speed/feed
- Welding: Most welding processes suitable
- Finishing: Paint, galvanize, or powder coat
Material Selection Guidelines
| Environment | Recommended Treatment | Notes |
|---|---|---|
| Indoor, dry | Paint or untreated | Basic rust protection needed |
| Indoor, humid | Galvanized or epoxy coated | Consider moisture resistance |
| Outdoor | Hot-dip galvanized | Maximum corrosion protection |
| Chemical exposure | Stainless steel or specialized coating | Material selection critical |
