Product Description

Galvanized wire rod, a pinnacle of metal fasteners, boasts an exquisite surface enhanced by galvanizing. Adorned with a protective zinc layer, it not only exudes superior corrosion resistance but also retains remarkable strength and wear resistance. This versatile masterpiece finds its applications spanning across mechanical, construction, and industrial domains, redefining standards of durability.
1. Definition and Structure
Basic composition: Crafted from premium quality carbon or alloy steel, each piece is meticulously enveloped in a zinc layer—either through hot-dip or cold galvanizing. The threaded design is expertly tailored, offering options of full or half tooth configurations, catering to diverse structural needs.
Common specifications: With diameters ranging from M6 to M36 and lengths extending up to 3 meters, each unit can be custom-designed to fulfill specific load-bearing requisites, ensuring adaptability in every application.
2. Core Features
Corrosion resistance: The zinc layer acts as a formidable barrier against oxygen and moisture, significantly prolonging the wire rod's lifespan. It is ideally suited for environments that are humid or exposed to the elements.
High strength: Available in strength grades of 8.8 and 12.9, these wire rods boast an impressive tensile strength exceeding 1100N/mm², making them perfect for high-load and demanding scenarios.
Surface treatment process:
Hot dip galvanizing: Delivers a robust and thick zinc layer (>85 microns), offering formidable corrosion resistance but with a characteristically rugged texture.
Cold galvanizing: Features a more delicate zinc layer (around 3-5 microns), presenting a smoother finish, yet provides limited rust prevention, suitable for environments with low corrosion potential.
3. Manufacturing process

1. Material selection: The choice of high-carbon or alloy steel (e.g., SCM435) ensures foundational mechanical excellence.
2. Forming and processing: Post cutting and forging/rolling, threading is meticulously executed using precision thread lathes or milling machines for accuracy.
3. Heat treatment: Through quenching and tempering, hardness and toughness are significantly enhanced, fortifying the wire rod’s durability and longevity.
4. Galvanizing treatment:
Hot dip galvanizing: A meticulous immersion in molten zinc results in a uniformly robust coating.
Cold galvanizing: This process involves the electrolytic deposition of zinc, producing a finer, elegant surface finish.
Application scenarios

Construction engineering: Ideal for securing steel structures and stabilizing scaffolding, these rods excel in weather-resistant applications.
Mechanical manufacturing: Perfect for fastening transmission systems, mold positioning, and high-temperature equipment like injection molding machines, delivering reliability under extreme conditions.
Transportation: Essential for connecting auto components and bridge structures, these rods provide unparalleled resistance to vibration and corrosion.
Galvanized wire rods are an exemplary fusion of zinc layer protection and high tensile strength, adeptly addressing the common issues of metal fastener corrosion and limited bearing capacity. They emerge as a premier choice across machinery and construction sectors. When applying, it is critical to select the appropriate galvanizing process and strength grade, considering the environmental conditions and load demands. Adhering to installation and maintenance guidelines ensures optimal performance and longevity.
