A stay rod assembly connects the stay wire to the ground anchor, stabilizing utility poles and transmission towers. The hardened metal rod supports mechanical loads, anchoring the stay wire securely to prevent leaning or swaying under environmental stresses such as wind loads and varying soil conditions. This ensures the structural integrity and safety of power distribution and telecommunications installations across diverse geographical regions.
Two primary types exist: bow type and tubular type. The bow type includes variations such as the stay bow, stay thimble, stay rod, and stay plate, commonly used in Southeast Asia. The tubular type encompasses eye rod and turnbuckle stay rod designs, with turnbuckle variants featuring adjustable components for tensioning, prevalent in Africa and Saudi Arabia. Each type addresses specific attachment needs and regional preferences.
Stay rod assemblies are manufactured from high-strength carbon steel, malleable cast iron, or alloy steel, with hot-dip galvanized coatings compliant with ISO 1461 standards. This galvanization provides corrosion resistance and protection against rust, ensuring durability in outdoor environments. Dimensions are customizable, with diameters typically ranging from M16 to M24 and lengths from 1500 mm to 3000 mm, tailored to project requirements and offering high tensile strength for significant mechanical loads.
Installation involves positioning the assembly diagonally from pole to ground anchor, with a portion buried underground for stable anchoring. Adjustable types allow tensioning during setup to optimize support. Professional manufacturers, primarily based in China, offer customizable solutions meeting regulatory standards, with quality assurance through certifications like ISO 9001.

Frequently Asked Questions (FAQS)
What is a stay rod assembly and what are its common applications?
A stay rod assembly connects stay wire to ground anchors, providing mechanical support to prevent leaning or swaying of utility poles. The assembly includes components like stay rods, guy wire clamps, pole bands, and other fittings. It is widely used in electrical power distribution systems, telecommunication lines, and tower structures, particularly in areas prone to high winds, soft soil, or environmental stresses, maintaining structural integrity across diverse geographical regions.
What types of stay rods are available?
Stay rods are divided into bow type and tubular type. Bow type includes stay bows, stay thimbles, stay plates, and stay rods, commonly used in Southeast Asia. Tubular type includes eye rods and turnbuckle rods (which are adjustable), typically used in Africa and Saudi Arabia. The choice depends on design and application requirements.
What materials are used and how are they protected against corrosion?
Stay rods are made from high-strength carbon steel, forged steel, or galvanized stainless steel. They are hot-dip galvanized according to ISO 1461 standards, providing a thick zinc coating that protects against rust and corrosion. This process ensures long-term reliability and performance in harsh weather conditions and challenging environments. Some components may use malleable cast iron or electroplating for additional protection.
How is a stay rod assembly installed?
Stay rod assemblies are installed diagonally from the utility pole to the ground or anchor point, typically at a 45-degree angle for optimal support. A portion remains above ground while the rest is buried. Installation should be performed by professionals to ensure safety and correctness. Adjustable types like turnbuckles allow for tensioning during setup. Manufacturers like RaxPower provide detailed installation manuals.
What specifications should I consider when ordering?
Key specifications include dimensions (diameter and length such as M16, M20, or custom sizes), weight, ultimate tensile strength (UTS), and load-bearing capacity. Standard sizes include M16x2000mm or M20x2400mm. Consider the installation environment, required strength, pole heights, environmental conditions, and load capacities to ensure proper selection for your project.
What quality control and safety measures are implemented?
We implement rigorous quality control including break load tests, dimensional accuracy inspections, and multi-stage testing throughout manufacturing. Raw material selection and hot-dip galvanization meet ISO standards, ensuring adherence to stringent load capacity, safety, and reliability criteria.
Do you offer customization for large-scale projects?
