Tubular tie rods are high-strength, adjustable metal connectors that are widely used in power lines, communication towers, building structures, etc. to withstand tension and maintain structural stability. As one of the core products of Handan Jinmai Fastener Manufacturing Co., Ltd., our tubular tie rods are made of high-quality steel and undergo strict quality inspections to meet the high standards of the power fittings industry. Since its establishment in 2010, the company has focused on the research and development and production of tie rods, power line accessories and forgings. With advanced equipment and a complete quality management system, it has become a trusted partner for domestic and foreign customers.
1. High strength and durability: High-quality carbon steel or alloy steel is selected and heat-treated to ensure that the pull rod has excellent tensile strength and fatigue resistance.
2. Customizable design: It supports customization of various diameters (such as Φ20mm, Φ30mm, etc.) and length specifications to meet different engineering requirements[7].
3. Anti-corrosion performance: The surface is treated with hot-dip galvanizing or Dacromet coating to effectively resist erosion in harsh environments such as moisture and salt spray.
4. Easy installation: Modular design, suitable for a variety of connection methods (such as threading, welding, and articulation), improving construction efficiency.
5. Wide applicability: It is suitable for scenarios such as power poles, bridge reinforcement, photovoltaic brackets, and communication towers.
1. Raw material selection: Q235 or Q345 steel that meets the GB/T 700 standard is used to ensure material uniformity and mechanical properties.
2. Forging and machining: Forging and precision machining are performed using friction presses and CNC lathes to ensure dimensional accuracy and surface finish[6].
3. Heat treatment and strengthening: The hardness and toughness of the material are improved through quenching and tempering processes to extend the service life of the product.
4. Surface treatment: Hot-dip galvanizing is used, with a coating thickness of ≥85μm, in line with ASTM B695 Class 50 standard[4].
5. Quality inspection: Each batch of products passes tensile tests, salt spray tests and dimensional inspections to ensure compliance with the ISO 9001 quality management system.
