The selection of high-quality, dimensionally accurate steel materials remains crucial for successful project execution across multiple industries. A specialized range of mechanical and structural steel square tubes has emerged as a versatile solution for various engineering requirements.
Key Advantages of Steel Square Tubes
These products offer several technical benefits that make them suitable for demanding applications:
- Certified Quality: Manufactured to comply with ASTM A513 (mechanical tubing) and ASTM A500 (structural tubing) standards, ensuring consistent strength, durability, and workability.
- Customization Options: Available in multiple sizes and wall thicknesses with precision cutting services to minimize material waste.
- Flexible Procurement: No minimum order requirements accommodate projects of varying scales.
Technical Specifications
Material Properties
| Standard | Chemical Composition | Mechanical Properties |
|---|---|---|
| ASTM A513 | Carbon: 0.17-0.23%, Manganese: 0.3-0.6%, Phosphorus: ≤0.04%, Sulfur: ≤0.05% | Tensile Strength: 132,000 psi (602 MPa), Yield Strength: 74,185 psi (512 MPa) |
| ASTM A500 | Carbon: ≤0.3%, Copper: ≤0.18%, Sulfur: ≤0.063%, Phosphorus: ≤0.05% | Varies by grade (A-D) with tensile strength ranging 45,000-62,000 psi |
Physical Characteristics
The tubes feature an uncoated, semi-smooth gray surface suitable for welding, painting, or other finishing processes. Wall thickness tolerance is maintained within ±10% for mechanical square tubes.
Common Applications
These steel square tubes serve multiple industrial sectors:
- Manufacturing equipment frames and structural components
- Construction elements and temporary supports
- Transportation equipment including trailer chassis
- Warehouse storage systems and display structures
- Various metal fabrication projects
