What is a Stay rod?

A stay rod, also known as a stay set, is a crucial component used to connect the stay wire to the ground anchor. There are two main types of stay rods: bow type and tubular type. The bow type includes stay bows, stay thimbles, stay plates, and stay rods, while the tubular type consists of eye stay rods and turnbuckle stay rods. The bow type is widely used in Southeast Asia, while the tubular type is mainly utilized in Africa and Saudi Arabia. Stay rods provide mechanical support to linked components, preventing collapse under extreme stress. They are essential in various applications such as supporting tower and power pole installations in the electric field and pole-line technologies in telecom and distribution lines.

The purpose of a stay rod in utility poles

A stay rod in utility poles serves the crucial purpose of providing stability and support to utility poles, transmission towers, and other structures. Its main function is to counteract the forces of wind, ice, and conductor weight to maintain structural integrity. Stay rods are essential components that connect stay wires to ground anchors, ensuring a firm connection and stability. They are made from materials like steel and aluminum that resist rust, corrosion, and harsh weather conditions. Stay rods have key features such as corrosion resistance, high tensile strength, anti-galloping features, high-load bearing capacity, adjustability in length, vibration dampening capabilities, ease of installation, and cost-effectiveness. The selection of stay rods involves considering factors like load-bearing capacity, torsional strength, cost-effectiveness, adjustability, maintenance requirements, and environmental impact. Stay rods play a vital role in various applications such as supporting transmission lines, wind turbines, lighting systems, telecommunication towers, and power installations

Quality compliance – ISO 1461

ISO 1461:2022 is an international standard that specifies the general properties of hot dip galvanized coatings and the test methods for these coatings applied to fabricated iron and steel articles, including certain castings. The standard is relevant for Stay Rod that are galvanized as part of their manufacturing process to provide corrosion protection.

Here are some key points from ISO 1461:2022 that relate to quality compliance:

• Scope: The standard applies to coatings applied by dipping fabricated iron and steel articles in a zinc melt containing not more than 2% of other metals. It does not apply to continuously hot dip galvanized sheet, wire, woven or welded mesh products, tube and pipe hot dip galvanized in automatic plants, or products for which specific standards exist.

• General Requirements: The standard outlines the requirements for the appearance, thickness, adhesion, and other properties of the galvanized coating. It also provides guidelines for the renovation of uncoated or damaged areas.

• Coating Thickness: The standard specifies the minimum coating thickness required for various categories of galvanized items. The thickness is a critical factor in ensuring the corrosion resistance of the galvanized coating.

• Coating Appearance: The standard describes the acceptable appearance of the galvanized coating, which should be smooth, uniform, and continuous. It also addresses various defects that can occur during the galvanizing process and their acceptability.

• Adhesion: The standard includes requirements for the adhesion of the galvanized coating to the steel substrate, which is essential for the coating's protective performance.

• Acceptance Criteria: ISO 1461:2022 provides criteria for accepting or rejecting galvanized products based on the coating's properties and any defects present.

• Sampling and Inspection: The standard references other ISO documents, such as ISO 2859, for sampling procedures and inspection by attributes, which are used to determine the quality of the galvanized coating.

• Safety and Process Requirements: Annex B of the standard provides safety and process requirements for hot dip galvanizing, ensuring that the process is carried out in a manner that meets quality standards.

• Declaration of Compliance: The standard requires a declaration of compliance, which means that manufacturers must provide evidence that their products meet the specified requirements.
