Product Description

Galvanized wire rods are exceptional metal fasteners that have undergone an advanced surface galvanizing process, enveloping them with a robust zinc layer. This enhancement vastly improves their resilience against corrosion while preserving their exceptional strength and wear resistance. Widely acclaimed across mechanical, construction, and industrial domains, these fasteners are indispensable for enduring performance.
1. Definition and Structure
Basic Composition: These fasteners are crafted from premium quality carbon steel or alloy steel, meticulously coated with a zinc layer through either hot-dip galvanizing or cold dip galvanizing. The threading can be customized as full tooth or half tooth structures, offering versatile application possibilities.
Common Specifications: With a diameter spectrum from M6 to M36 and lengths extending up to 3 meters or tailored to specific needs, these rods cater to diverse load-bearing demands with precision.
2. Core Features
Corrosion Resistance: The protective zinc layer acts as a formidable barrier against oxygen and moisture, significantly prolonging the product's service life. This feature makes it especially advantageous for humid or outdoor environments.
High Strength: Available in strength grades 8.8 and 12.9, these rods boast an impressive tensile strength exceeding 1100N/mm², ideal for high-load applications and ensuring outstanding performance.
Surface Treatment Process:
Hot Dip Galvanizing: This method yields a thick zinc coating (>85 microns), providing profound corrosion resistance with a slightly coarse surface texture.
Cold Galvanizing: Producing a thinner zinc layer (approximately 3-5 microns), this technique results in a smoother finish, suitable for environments with minimal corrosive threats.
3. Manufacturing Process

1. Material Selection: The selection of high carbon steel or alloy steel, such as SCM435, ensures robust mechanical properties essential for demanding applications.
2. Forming and Processing: Following cutting, forging, or rolling, threads are meticulously crafted using a thread lathe or milling machine for precise configurations.
3. Heat Treatment: Through quenching and tempering, the rods achieve enhanced hardness and toughness, ensuring superior durability and longevity.
4. Galvanizing Treatment:
Hot Dip Galvanizing: Submersion in molten zinc creates a uniform, comprehensive coating, optimizing resistance.
Cold Galvanizing: Electrolytic deposition forms a finer zinc layer, offering a sleek finish.
Application Scenarios

Construction Engineering: Ideal for connecting steel frameworks and anchoring scaffolding, excelling in weather resistance.
Mechanical Manufacturing: Perfect for securing transmission systems, mold positioning, and high-temp apparatus like injection molding machinery.
Transportation: Integral for coupling components in vehicles and bridges, these rods withstand vibrational and corrosive challenges.
Galvanized wire rods seamlessly blend zinc coating protection with formidable strength, addressing the recurring challenges of corrosion and limited bearing capacity in metal fasteners. They emerge as an exemplary selection in machinery and construction sectors. For optimal results, selecting the appropriate galvanizing process and strength grade is vital, guided by environmental and load considerations, while adhering to installation and maintenance protocols for assured performance.
