Product Details
Standard Compliance:
GB/T 5223.3-2017 (equivalent to GB/T 5224-2014 level)
ASTM A722
Ruibaolong’s High-Strength PC Bar is a premium prestressing solution engineered for High-Strength Prestressed Concrete (PHC) pipe piles, electric poles, and large-scale foundation engineering.
Manufactured using advanced induction quenching and tempering technology, our PC Bars deliver an optimal balance of ultra-high tensile strength, excellent ductility, and long-term structural reliability.
Technical Specifications & Typical Applications
We offer four precision-engineered diameters to meet diverse load-bearing requirements:
| Diameter | Primary Applications | Structural Benefit |
|---|---|---|
| 7.1 mm | Small & medium electric poles, light-duty pipe piles, civil foundations | Optimized for light structural reinforcement |
| 9.0 mm | Heavy-duty pipe piles, power transmission foundations, industrial plants | High tension with excellent material efficiency |
| 10.7 mm | Port foundations, Metro/LRT supports, bridge piers | Designed for high-load-bearing environments |
| 12.6 mm | Massive infrastructure, deep-water port piles, heavy rail systems | Maximum rigidity for extreme structural demands |
Core Performance Advantages
Ultra-Low Relaxation Performance
Under 70% σₘ stress conditions, the 1000-hour relaxation rate ≤ 1.5%, ensuring long-term prestress retention and structural safety.
Superior Mechanical Consistency
Fully automated production lines minimize variation in:
Tensile strength
Elongation
Elastic modulus
This consistency is critical for mass PHC pile production and quality-controlled infrastructure projects.
High Construction Efficiency
Supplied as high-rigidity straight bars, enabling:
Fast positioning
Accurate tensioning
Reduced on-site labor time
Advanced Heat Treatment Control
Our in-house laboratory continuously monitors Sorbite microstructure (索氏体) to ensure:
Excellent fatigue resistance
Stable mechanical behavior under cyclic loads
Precision Manufacturing Process
Our integrated production flow guarantees quality from raw material to finished product:
Raw material unwinding → Descaling → Wire drawing → Straightening → Precision drawing →
Induction quenching & water cooling → Tempering & water cooling → Cutting → Finished product winding
Each step is strictly controlled to meet prestressed concrete engineering standards.
