ASTM A500 round tubing is a cold-formed electric-resistance-welded (ERW) carbon steel structural pipe, specifically designed for building frames, bridge components, and industrial support systems. Known for its high strength and excellent sectional properties, it serves as a cost-effective alternative to traditional hot-rolled steel sections.
Standard: ASTM A500 Grade B/C
Material: Carbon steel (C≤0.26%)
Process: Cold-formed + ERW
Shapes: Round (Square/Rectangular available)
Surface:
Black (Mill finish)
Hot-dip galvanized (Optional, ≥80μm zinc coating)
✓ High Strength-to-Weight Ratio: 20% stronger than conventional sections with 15% weight reduction
✓ Precision Geometry: Cold-forming ensures tight tolerances (Ovality ≤1%)
