Types & Applications
Manufacturing Processes
- Hot Rolled: 5.5-250mm diameter range - 5.5-25mm for bolts and mechanical parts, larger diameters for machinery components and seamless steel pipe billets
- Forged: Enhanced strength through controlled deformation
- Cold Drawn: Improved surface finish and dimensional accuracy
Key Differentiator
Round steel features smooth, grain-free surfaces without ribs, providing distinct mechanical properties compared to ribbed or grooved steel bars.
