Screw Thread Steel Bars: Engineered for Strength, Built to Last
Screw thread steel bars, also known as prestressed threaded reinforcement bars, are the backbone of modern heavy-duty construction. Designed for critical applications like bridges, slope stabilization, and seismic-resistant structures, our ASTM-certified bars deliver unmatched tensile strength, corrosion resistance, and installation efficiency.
