Product Description

Galvanized wire rod represents a pinnacle in metal fastener technology, boasting a protective zinc coating that shields against corrosion while preserving exceptional strength and wear resistance. This innovative product is a favorite across mechanical, construction, and industrial sectors due to its robust performance and reliability.
1. Definition and Structure
Basic Composition: Crafted from premium quality carbon or alloy steel, this product features a protective zinc layer achieved through either hot-dip or cold dip galvanization. The threading is versatile, available in full or half configurations, to meet diverse application needs.
Common Specifications: With diameters ranging from M6 to M36 and lengths extending up to 3 meters or customized to specific requirements, this product adapts to a wide array of load-bearing situations.
2. Core Features
Corrosion Resistance: The zinc coating acts as a formidable barrier against oxygen and moisture, thereby significantly prolonging service life. This makes it especially suitable for use in humid or outdoor environments.
High Strength: Available in grades 8.8 and 12.9, these products deliver exceptional tensile strength exceeding 1100N/mm², making them perfect for demanding high-load applications.
Surface Treatment Process:
Hot Dip Galvanizing: Known for its thick zinc layer (usually >85 microns), this process provides robust corrosion resistance, albeit with a slightly coarser surface finish.
Cold Galvanizing: This method results in a thinner zinc layer (about 3-5 microns), offering a sleek, smooth surface optimal for environments with low corrosion risk.
3. Manufacturing Process

1. Material Selection: Using high carbon steel or alloy steel such as SCM435 ensures foundational mechanical strength and durability.
2. Forming and Processing: Post-cutting, forging, or rolling, threads are meticulously crafted using advanced thread lathes or milling machinery.
3. Heat Treatment: A precise quenching and tempering process enhances hardness and toughness, thereby boosting longevity.
4. Galvanizing Treatment:
Hot Dip Galvanizing: The metal is immersed in molten zinc, forming a consistent and durable coating.
Cold Galvanizing: Involves the electrolytic deposition of zinc to create a finely textured surface finish.
Application Scenarios

Construction Engineering: Ideal for linking steel structures and securing scaffolding, these fasteners excel in weather-resistant applications.
Mechanical Manufacturing: Essential for securing transmission systems, precise mold positioning, and withstanding high temperatures in equipment like injection molding machines.
Transportation: Perfect for joining components in cars and bridges, offering both vibration resistance and corrosion protection.
Galvanized wire rods ingeniously combine zinc protection with superior strength, addressing common issues of corrosion susceptibility and inadequate load capacity in metal fasteners. In practical applications, it is crucial to select the appropriate galvanizing technique and strength grade tailored to environmental and load demands, ensuring adherence to installation and maintenance standards for optimal performance.
