5mm Helical PC Wire for Prestressed Concrete
The 5mm Helical PC Wire is a high-strength prestressed concrete steel wire manufactured from premium carbon steel. Its spiral (helical) surface design provides excellent bonding with concrete, ensuring strong mechanical interlock, reliable load transfer, and long-term structural stability.
Designed for bridges, buildings, and heavy-load concrete structures, this helical prestressed wire delivers high tensile strength, corrosion resistance, and consistent performance under demanding service conditions.Key Advantages of 5mm Helical PC Wire
Helical PC wire is engineered to deliver strong prestressing force, superior bonding, and long service life in prestressed concrete applications.
Primary Advantages
High tensile strength and excellent elasticity, suitable for heavy-load prestressed structures
Superior bonding with concrete due to spiral surface design, improving prestress efficiency
Stable mechanical performance under long-term loading
Consistent diameter and smooth surface finish, ensuring easy installation and anchorage
Low relaxation performance, maintaining prestressing force over time
Good corrosion resistance, suitable for harsh and aggressive environments
Manufactured to meet multiple international standards, ensuring global acceptance
