Bow Stay Rod is a core hardware used to stabilize poles, towers and overhead lines in power transmission and distribution systems. It is designed to withstand strong winds, snow and ice loads, and mechanical tension. Its unique bow-shaped structure can effectively disperse the tension and prevent the poles and towers from tilting or collapsing. It is widely used in substations, transmission lines, communication base stations and other scenarios. Handan Jinmai Fastener Manufacturing Co., Ltd. uses advanced technology to produce high-reliability Bow Stay Rods to meet the needs of power engineering in harsh environments around the world.
1. High-strength tensile design
Made of high-quality alloy steel, the ultimate tensile strength is ≥600MPa, and it can withstand extreme load impact.
2. Super strong anti-corrosion performance
The thickness of the hot-dip galvanized layer is ≥86μm (in accordance with ASTM A153 standard), and the salt spray test is more than 1000 hours without red rust, which is suitable for high-corrosion environments such as coastal areas and industrial areas.
3. Wide engineering adaptability
Provide customized length (1.5m-6m) and end connection methods (threaded/eye/flange), compatible with all types of tower foundations.
4. Anti-seismic buffer structure
The elastic deformation design of the bow area can absorb instantaneous impact force and reduce the risk of fatigue damage to the tower structure.
5. Low maintenance cost throughout the life cycle
The 30-year replacement-free design significantly reduces the power grid operation and maintenance expenses.

Handan Jinmai strictly implements the four-stage precision manufacturing process:
1. Material selection
Select S355JR structural steel blank (EN 10025 standard), and spectral analysis ensures accurate element content.
2. Hot forging
1200℃ die forging to eliminate internal defects and improve metal streamline density.
3. Heat treatment strengthening
Tempering treatment (quenching + tempering) makes the hardness reach HRC28-32 and optimizes the balance of strength and toughness.
4. Triple anti-corrosion protection
Pickling and rust removal → plating treatment → 450℃ hot dip galvanizing → passivation and sealing to achieve all-round protection.
