Product Description

Galvanized wire rods represent a pinnacle in metal fastening technology. With meticulous surface galvanizing treatment, they boast a robust zinc layer that significantly heightens corrosion resistance while preserving remarkable strength and enduring wear resistance. Pervasively utilized across mechanical, construction, and industrial sectors, these fasteners are indispensable for their superior durability.
1. Definition and Structure
Basic Composition: Crafted from premium-grade carbon steel or alloy steel, each piece is enveloped in a zinc layer—available as either hot-dip galvanized or cold dip galvanized. The threaded section can be custom-designed as a full tooth or half tooth structure to suit diverse applications.
Common Specifications: With diameters ranging from M6 to M36 and lengths stretching up to 3 meters, these rods can also be custom-tailored to meet varying load-bearing specifications, ensuring versatility in application.
2. Core Features
Corrosion Resistance: The zinc layer acts as a formidable barrier against oxygen and moisture, significantly prolonging the product's lifespan. This makes it exceptionally suited for humid or outdoor environments where corrosion is a constant threat.
High Strength: Available in strength grades 8.8 and 12.9, these rods offer impressive tensile strength exceeding 1100N/mm². They are perfectly engineered for high-load scenarios, making them a reliable choice for demanding applications.
Surface Treatment Process:
Hot Dip Galvanizing: Features a thick zinc layer, typically over 85 microns, providing robust corrosion resistance, albeit with a slightly rough surface texture.
Cold Galvanizing: Characterized by a thin zinc layer, about 3-5 microns, it offers a smooth surface but with limited rust prevention capability, suitable for environments with low corrosion demands.
3. Manufacturing Process

1. Material Selection: High carbon steel or alloy steel such as SCM435 is meticulously chosen to ensure superior mechanical properties, forming the foundation of the product's strength and resilience.
2. Forming and Processing: Following precision cutting, forging, or rolling, threads are expertly crafted using thread lathes or milling machines to achieve exacting specifications.
3. Heat Treatment: Through a rigorous process of quenching and tempering, these rods gain enhanced hardness and toughness, ensuring they deliver long-lasting durability.
4. Galvanizing Treatment:
Hot Dip Galvanizing: Submerges the rod in molten zinc to create a uniform protective coating, providing excellent coverage and durability.
Cold Galvanizing: Utilizes electrolytic deposition to apply a zinc layer with a refined surface finish, offering a sleek appearance.
Application Scenarios

Construction Engineering: Perfect for connecting steel structures and securing scaffolding, these rods exhibit outstanding weather resistance, ensuring reliable performance in challenging environments.
Mechanical Manufacturing: Ideal for fastening in transmission systems, mold positioning, and high-temperature equipment, such as injection molding machines, they guarantee steadfast performance.
Transportation: Essential for connecting components in vehicles and bridges, these rods offer unparalleled resistance to vibration and corrosion, ensuring structural integrity and safety.
Galvanized wire rods masterfully integrate zinc layer protection with high strength, addressing the challenges of metal fasteners prone to corrosion and inadequate load capacity. An exemplary choice in both machinery and construction, it is crucial to select the appropriate galvanizing process and strength grade based on environmental conditions and load requirements. Adherence to installation and maintenance specifications ensures optimal performance.
