Product Description

Galvanized wire rod is a superior type of metal fastener that has undergone a meticulous surface galvanizing treatment. It is enveloped with a robust zinc layer, dramatically enhancing corrosion resistance while maintaining outstanding strength and remarkable wear resistance. This makes it a sought-after choice across diverse sectors, including mechanical, construction, and industrial fields.
1. Definition and Structure
Basic composition: Crafted from premium-grade carbon steel or alloy steel, this exceptional product is adorned with a zinc layer (hot-dip or cold dip galvanized) on the surface. The threaded section can be intricately designed as a full tooth or half tooth structure, catering to various needs.
Common specifications: Available in a versatile diameter range from M6 to M36, with lengths reaching up to 3 meters. Customized options are available to perfectly meet distinct load-bearing requirements.
2. Core Features
Corrosion resistance: The expertly applied zinc layer acts as a formidable barrier against oxygen and moisture, significantly prolonging its service life. This makes it particularly suitable for humid or outdoor environments with challenging conditions.
High strength: Common strength grades of 8.8 and 12.9 boast a tensile strength exceeding 1100N/mm². This makes them ideal for high load scenarios, delivering reliable performance under demanding conditions.
Surface treatment process:
Hot dip galvanizing: Known for its thick zinc layer (typically >85 microns), offering exceptional corrosion resistance. While the surface might be slightly rough, its protective qualities are unmatched.
Cold galvanizing: Features a thinner zinc layer (approximately 3-5 microns), presenting a smooth surface. Though its rust prevention ability is moderate, it is excellently suited for environments with low corrosion.
3. Manufacturing process

1. Material selection: Employing high carbon steel or alloy steel (such as SCM435) ensures top-notch basic mechanical properties, laying the foundation for a reliable product.
2. Forming and processing: Post cutting, the process involves forging/rolling, with threads meticulously crafted by a thread lathe or milling machine for precision and quality.
3. Heat treatment: The process of quenching and tempering enhances hardness and toughness, significantly boosting durability and longevity.
4. Galvanizing treatment:
Hot dip galvanizing: Involves immersing in molten zinc solution, resulting in a uniform and robust coating that offers supreme protection against external elements.
Cold galvanizing: Utilizes electrolytic deposition to form a zinc layer, creating a finer, smoother surface finish.
Application scenarios

Construction engineering: Essential for connecting steel structures and securing scaffolding, thanks to its formidable weather resistance and reliability.
Mechanical manufacturing: Ideal for fastening in transmission systems, precise mold positioning, and high-temperature equipment such as injection molding machines.
Transportation: Perfect for connecting critical components in vehicles and bridges, where resistance to vibration and corrosion is paramount.
Galvanized wire rods seamlessly combine the protective power of a zinc layer with remarkable high strength. This addresses the challenges of metal fasteners being susceptible to corrosion and inadequate bearing capacity, making them the ideal choice for applications in machinery and construction. When deploying these rods, it is crucial to wisely select the galvanizing process and strength grade based on environmental and load demands, following precise specifications for installation and maintenance to ensure optimal performance.
