Product Description

Galvanized wire rod stands as a pinnacle of metallic fastening innovation, having undergone a precise surface galvanizing treatment. Enveloped in a protective zinc layer, this rod exudes unparalleled corrosion resistance while preserving robustness and exceptional wear resistance. Its versatility extends across mechanical, construction, and industrial domains, marking it as an indispensable component for professionals seeking reliability and durability.
1. Definition and Structure
Basic composition: Expertly crafted from premium-grade carbon steel or alloy steel, this rod boasts a zinc layer (achieved through hot-dip or cold galvanizing) that adorns its surface. The threaded section offers flexibility with a full or half tooth design, catering to diverse application needs.
Common specifications: Offering a versatile diameter range from M6 to M36, with lengths extending up to 3 meters or customized to meet varying load-bearing demands, ensuring adaptability across numerous applications.
2. Core Features
Corrosion resistance: The zinc layer serves as a formidable barrier against oxygen and moisture, significantly prolonging its service life. It becomes the preferred choice for environments that are humid or exposed to the elements.
High strength: With strength grades like 8.8 and 12.9, this rod delivers a tensile strength exceeding 1100N/mm², making it the perfect solution for high-load scenarios that demand reliability and endurance.
Surface treatment process:
Hot dip galvanizing: Features a thick zinc layer (typically >85 microns) offering formidable corrosion resistance, though the surface may appear slightly rough, providing rugged protection.
Cold galvanizing: Presents a thinner zinc layer (around 3-5 microns) resulting in a smoother finish, best suited for environments with low corrosion exposure.
3. Manufacturing process

1. Material selection: Utilizing high carbon steel or alloy steel (such as SCM435) ensures the rod's fundamental mechanical excellence, catering to demanding applications.
2. Forming and processing: Undergoes precise cutting, forging, and rolling, with threads meticulously shaped by state-of-the-art thread lathes or milling machines.
3. Heat treatment: By employing quenching and tempering, the rod's hardness and toughness are optimized, enhancing overall durability and resilience.
4. Galvanizing treatment:
Hot dip galvanizing: Immerses the rod in molten zinc, ensuring a uniform, robust coating that stands the test of time;
Cold galvanizing: Utilizes electrolytic deposition for a finer surface finish, ideal for aesthetic and functional applications.
Application scenarios

Construction engineering: Essential for connecting steel structures and securing scaffolding, it boasts unparalleled weather resistance, making it ideal for outdoor projects.
Mechanical manufacturing: Perfect for fastening in transmission systems, mold positioning, and high-temperature equipment like injection molding machines, ensuring precision and reliability.
Transportation: Vital for connecting vehicle and bridge components, offering superb resistance to vibration and corrosion, ensuring safety and longevity.
Galvanized wire rods skillfully merge zinc layer protection with high strength, effectively addressing the challenge of metal fasteners being vulnerable to corrosion and insufficient load-bearing capacity. They emerge as the optimal choice across machinery and construction landscapes. It is imperative to judiciously select the galvanizing process and strength grade tailored to the environment and load requirements, while adhering to specifications for installation and maintenance, to ensure optimal performance.
