Product Description

Galvanized wire rod is a sophisticated metal fastener that has undergone a meticulous surface galvanizing treatment. Enveloped in a robust zinc coating, it significantly enhances resistance against corrosion while retaining exceptional strength and wear resistance. This versatile component finds its indispensable use across a myriad of fields, including mechanical, construction, and industrial sectors.
1. Definition and Structure
Basic Composition: Crafted from premium-quality carbon steel or alloy steel, it is enveloped in a zinc layer through either hot-dip or cold-dip galvanizing techniques. The threaded section is expertly engineered to feature either a full or half-tooth structure to accommodate diverse application needs.
Common Specifications: With a diameter range of M6 to M36 and lengths extending up to 3 meters, these screws can also be customized to meet specific load-bearing requirements, offering unparalleled versatility.
2. Core Features
Corrosion Resistance: The zinc layer acts as a formidable barrier against oxygen and moisture infiltration, significantly extending the product's service life. This feature makes it exceptionally well-suited for humid or outdoor environments.
High Strength: Available in strength grades of 8.8 and 12.9, it boasts a tensile strength surpassing 1100N/mm², making it a perfect fit for high-load scenarios.
Surface Treatment Process:
Hot Dip Galvanizing: Characterized by a thick zinc layer (typically >85 microns) that provides robust corrosion resistance, albeit with a slightly rough surface texture.
Cold Galvanizing: Features a thinner zinc layer (approximately 3-5 microns) with a smoother surface, though it offers reduced rust prevention, thus best suited for low-corrosion environments.
3. Manufacturing Process

1. Material Selection: Employing high carbon steel or alloy steel like SCM435 ensures superior basic mechanical properties.
2. Forming and Processing: Following precise cutting and forging/rolling, the threads are meticulously crafted using thread lathes or milling machines to ensure accuracy and precision.
3. Heat Treatment: A combination of quenching and tempering processes is applied to bolster hardness, enhance toughness, and improve overall durability.
4. Galvanizing Treatment:
Hot Dip Galvanizing: Involves immersing the material in molten zinc to form a consistently uniform coating.
Cold Galvanizing: Entails electrolytic deposition of the zinc layer, achieving a finely detailed surface finish.
Application Scenarios

Construction Engineering: Perfect for connecting steel structures and securing scaffolding, these fasteners offer outstanding weather resistance.
Mechanical Manufacturing: Ideal for fastening in transmission systems, mold positioning, and high-temperature equipment such as injection molding machines.
Transportation: Essential for connecting components in vehicles and bridges, where resistance to vibration and corrosion is paramount.
Galvanized wire rods masterfully unite the protective power of a zinc coating with remarkable structural strength. Addressing common issues such as vulnerability to corrosion and inadequate load capacity, they are the quintessential choice in industries like machinery and construction. It is crucial to select the appropriate galvanizing process and strength grade based on specific environmental and load requirements. Following strict installation and maintenance guidelines ensures optimal performance.
