Questions You Should Know about PC Steel Bar

PC Steel Bar

Prestressed concrete steel bars, commonly known as PC steel bars, are renowned for their remarkable strength and durability. They exhibit low relaxation properties, strong adhesion with concrete, and excellent workability, making them an ideal choice in many construction scenarios. For instance, one can replace a 20mm hot-rolled steel bar with a mere 11mm PC steel bar.

These bars are extensively used in high-strength prestressed concrete applications, such as centrifugal pipe piles, electric poles, and viaduct piers.
