Maximize Mining Support Production: Zhongsheng Double-Line FRP Rock Bolt Pultrusion Machine

With infrastructure and mining industries shifting toward non-corrosive, high-strength support materials, Fiber Reinforced Polymer (FRP) rock bolts—also known as fiberglass anchor bolts or composite roof bolts—have rapidly replaced traditional steel rebars. The demand for lightweight, high-tensile, and corrosion-resistant mining bolts is at an all-time high.

For composite manufacturers seeking a reliable, high-yield solution, Henan Zhongsheng Composite Materials Co., Ltd. (www.frpzs.com) presents its flagship 1-out-of-2 FRP Rock Bolt Production Line. Spanning 45 meters, this heavy-duty automated line is engineered specifically to meet the strict thread and depth requirements of geological engineering, coal mine support, and tunnel linings.

High-Precision Thread Winding & Modular Double-Line Efficiency

FRP rock bolts require extreme threading precision to secure reliable anchorage in soil and rocks. Standard multi-line machines often struggle with inconsistent tooth depth or fibers twisting. Zhongsheng overcomes this by adopting a modular, high-precision 1-out-of-1 winding forming design.

By integrating two independent 1-out-of-1 systems into a single pultrusion machine frame, our 1-out-of-2 rock bolt line achieves high-volume output while offering absolute flexibility. Each line operates with independent caterpillar traction and speed regulation, allowing operators to adjust parameters for each run without cross-interference.

Advanced Specifications of Zhongsheng GFRP Rock Bolt Equipment

• Optimal Thread Range: Supports threaded bolts and rebars with diameters up to Max. 32 mm.
• Powerful Traction Force: Equipped with dual variable frequency continuous drives delivering Max. 2 x 20 KN traction.
• Caterpillar Gripper Design: Long 1,500mm effective caterpillar clamping with wear-resistant rubber tracks prevents rebar surface or rib damage.
• Tracking Shearing Unit: Features a high-speed automatic flying cut-off with a 700mm tracking stroke, synchronized with length-counting systems for millimetric length accuracy.
• Power Supply & Footprint: Designed with a total power of 65 KW (380V/50Hz) and is compactly configured inside a 45m x 2.5m x 2.5m dimension.

Industrial-Grade Components & Turnkey Recipe Formulas

We believe that high-quality machinery is built on reliable components. The Zhongsheng rock bolt production line is pre-assembled with premium international electrics: OMRON smart temperature controllers, Schneider circuit breakers, relays, and switches, and Inovance PLC programmers. Every component satisfies first-class energy efficiency standards to keep your long-term operational costs low.

More than just equipment supply, Zhongsheng provides complete turnkey technology transfer. We dispatch 2 professional technicians to support you on-site during installation, operator training, and raw material chemical formulation transfer (resin/glass fiber mixing ratios), ensuring your team can perfectly adjust rebar threads and tooth depths from day one.
