3Surface Types
Spiral Ribbed Type
1)Features continuous spiral ribs along the surface of the bar.
2)Enhances mechanical interlock and bonding strength with concrete.
3)Commonly referred to as Spiral Ribbed PC Steel Bar.
Plain Surface Type
1)Features a smooth, rib-free surface.
2)Prestressing force is transferred primarily through end anchorage systems rather than bond action.
3)Suitable for specific prestressed concrete applications requiring anchored load transfer.
