Stay Rods are an indispensable support component in the construction of power transmission, communication towers and optical cable networks, and are designed to fix and stabilize overhead lines. The stay rods produced by Handan Jinmai Fastener Manufacturing Co., Ltd. are made of high-strength steel and are hot-dip galvanized on the surface. They have excellent corrosion resistance and mechanical strength and are suitable for extreme weather conditions and high-load scenarios. The products are widely used in power transmission and distribution lines, substations, communication base stations, railway contact networks and other fields, providing safe and reliable anchoring support for infrastructure.
1. High-quality materials
Q235B/Q345B high-strength carbon steel or alloy steel is used to ensure tensile strength ≥375MPa, meeting stringent load-bearing requirements.
2. Precision structural design
The rod body thread adopts roll forming technology, combined with standardized connectors, to achieve fast installation and high-precision matching.
3. Long-term anti-corrosion
The surface is hot-dip galvanized (zinc layer thickness ≥85μm) or electroplated galvanized + passivation process, passed ISO 1461 standard salt spray test, and is suitable for humid, coastal and other corrosive environments.
4. Customized service
Supports non-standard size customization, provides M12-M48 multiple diameter specifications, and a length range of 1-6 meters to meet the needs of different engineering scenarios.
5. Safety certification
It complies with international standards such as GB/T 700 and ASTM A36, and has passed the fatigue test of a third-party organization to ensure long-term stability.
1. Raw material screening
Select high-quality steel billets, and use a spectrometer to test the chemical composition to ensure that the ratio of carbon, silicon, manganese and other elements meets the standards.
2. Precision forging
The rod body is formed by die forging, and the thread is processed by CNC machine tools, with an accuracy of ISO 6g tolerance.
3. Heat treatment and strengthening
The hardness of the material is improved (HRC 22-30) through quenching + tempering process, internal stress is eliminated, and the deformation resistance is enhanced.
4. Surface treatment
The coating is completed by a fully automatic hot-dip galvanizing line, supplemented by passivation and sealing, to achieve 360° anti-corrosion protection without dead ends.
5. Strict quality inspection
Magnetic particle inspection, tensile test and coating thickness detection are carried out piece by piece, and the qualified products are laser marked with traceability information.
