Product Description

Galvanized wire rod, a remarkable metal fastener, has been expertly treated with a galvanizing surface process. Encased in a protective zinc layer, it boasts exceptional corrosion resistance while maintaining outstanding strength and wear resistance. This versatile component finds its place across various sectors including mechanical, construction, and industrial fields, providing reliable performance and durability.
1. Definition and Structure
Basic Composition: Crafted from top-tier carbon or alloy steel, this fastener features a surface zinc layer, applied through either hot-dip or cold dip galvanizing. The threaded section is available in full tooth or half tooth designs, offering bespoke solutions for diverse applications.
Common Specifications: Diameter range spans from M6 to M36, with lengths extending up to 3 meters or tailored to meet specific load-bearing needs, ensuring flexibility and adaptability for various uses.
2. Core Features
Corrosion Resistance: The zinc coating acts as a robust barrier against oxygen and moisture, significantly prolonging the service life of the fastener, making it ideal for humid or outdoor environments where durability is key.
High Strength: Available in strength grades 8.8 and 12.9, these fasteners boast a tensile strength exceeding 1100N/mm², making them perfect for demanding, high-load scenarios.
Surface Treatment Process:
Hot Dip Galvanizing: Features a thick zinc layer (usually >85 microns), offering formidable corrosion resistance, although the texture is slightly coarse.
Cold Galvanizing: Characterized by a thinner zinc layer (around 3-5 microns), it presents a smooth finish, primarily suitable for environments with lower corrosion exposure.
3. Manufacturing Process

1. Material Selection: High carbon steel or premium alloy steel (e.g., SCM435) is chosen to ensure essential mechanical properties are met.
2. Forming and Processing: Following cutting, the product undergoes forging/rolling, with threads meticulously crafted using a thread lathe or milling machine.
3. Heat Treatment: Through quenching and tempering, we enhance the hardness and toughness of the fasteners, augmenting their durability for prolonged use.
4. Galvanizing Treatment:
Hot Dip Galvanizing: Involves immersion in molten zinc to create a uniform protective coating;
Cold Galvanizing: Utilizes electrolytic zinc deposition, resulting in a finer surface finish.
Application Scenarios

Construction Engineering: Essential for connecting steel structures and securing scaffolding, offering robust weather resistance and stability.
Mechanical Manufacturing: Vital for securing transmission systems, mold positioning, and high-temperature equipment like injection molding machines.
Transportation: Plays a crucial role in linking components in vehicles and bridges, providing resistance to both vibration and corrosion.
Galvanized wire rods seamlessly merge zinc layer protection with unparalleled strength, addressing the challenges of metal fasteners prone to corrosion and inadequate load-bearing capacity. They emerge as a premier choice in machinery and construction domains. When deployed, it is vital to select the appropriate galvanizing process and strength grade based on environmental and load requisites, adhering to installation and maintenance guidelines for optimal performance.
