Details
Product Overview
PT Bar (Post-Tension Bar) and prestressing steel bar are high-strength steel bars used for prestressed concrete structures. Also known as post-tension steel bar, prestressed tendon bar, or high-strength threaded bar, these products provide mechanical anchorage, high yield strength, and excellent fatigue resistance.
They are widely applied in bridges, tunnels, geotechnical projects, and structural reinforcement, providing reliable load transfer and long-term structural safety.
