In the world of heavy civil construction—be it slope stabilization , tunnel support , or deep excavation,post tension project—time is the most expensive currency.
Yet, many projects still rely on traditional rebar, burning daylight (and money) on-site with electric welders, waiting for cooling periods, and inspecting joints for cracks. In high-humidity environments or water-scarce locations, this isn't just slow; it’s a safety liability.
There is a smarter way: Prestressing Thread Bars (PT Bar/Rock Bolt).
Unlike standard deformed bars, our PT Bars /Rock Bolt feature a full-length continuous thread. This design fundamentally changes the installation logic:
◎ Zero Welding Required: Connections are made via couplers and nuts. What used to take 20 minutes of welding now takes 90 seconds of threading.
◎ Consistent Tensioning: Achieve accurate pre-stress force without the thermal distortion caused by welding. This is critical for slope anchors where long-term stability depends on constant tension.
◎ All-Weather Installation: Rain or shine, underground or on a cliffside, the mechanical connection works instantly. No power supply? No problem. Manual wrenches work perfectly.
◎ Reusable Components: In temporary applications like formwork tie rods , the bars and anchors can be disassembled and reused, drastically reducing material waste.
◎ Less is More: Thanks to the superior strength of PT Bars/rock bolt, you need significantly fewer units to meet structural requirements compared to conventional rebar. Fewer bars mean less crane time, fewer lifts, and drastically reduced physical strain on the crew.
The PT bar price may high a little then rebar screw with thread bar,in fact, now the PT bar very similar to rebar anchor bolt price,but when you calculate the "Total Cost of Ownership" (TCO)—factoring in labor, equipment rental, and delay penalties—the slightly higher unit price of a PT Bar becomes negligible compared to the massive savings in operational efficiency.
Lt’s start investing in speed.
We supply fully threaded PT Bars (PSB830/930/1080) with matched nuts, couplers, and bearing plates. Custom lengths and export-standard anti-rust packaging available.
