Product Description

Galvanized wire rod is an exceptional type of metal fastener that has been meticulously enhanced through a surface galvanizing treatment. Enrobed in a protective zinc layer, this fastener boasts remarkable corrosion resistance while retaining its impressive strength and wear resistance. Its application is widespread across the mechanical, construction, and industrial sectors, where it is valued for its durability and reliability.
1. Definition and Structure
Basic composition: Constructed from high-grade carbon steel or alloy steel, this wire rod is sheathed in a zinc layer achieved through either hot-dip galvanization or cold dip galvanization. The threaded segment can be adapted to either a full tooth or half tooth configuration, providing versatile utility.
Common specifications: Catering to various needs, it offers a diameter range from M6 to M36 and an extendable length reaching up to 3 meters. For bespoke applications, customization is available to satisfy diverse load-bearing requirements.
2. Core Features
Corrosion resistance: The zinc layer serves as a formidable barrier against oxygen and moisture, significantly prolonging the fastener's service life. This feature makes it particularly advantageous in humid or outdoor environments where longevity is paramount.
High strength: With strength grades of 8.8 and 12.9, it provides a remarkable tensile strength exceeding 1100N/mm², making it suitable for high-load scenarios where performance cannot be compromised.
Surface treatment process:
Hot dip galvanizing: This process results in a robust zinc layer, generally greater than 85 microns thick, offering formidable corrosion resistance, albeit with a slightly rough surface texture.
Cold galvanizing: Features a finer zinc layer approximately 3-5 microns thick, providing a smooth finish. While its rust prevention is less robust, it is ideal for environments where corrosion risk is minimal.
3. Manufacturing process

1. Material selection: Utilizing high carbon steel or alloy steel, such as SCM435, ensures that the fundamental mechanical properties are met, setting a reliable foundation for the end product.
2. Forming and processing: Post cutting, the material undergoes forging or rolling, followed by threading via precision thread lathes or milling machines to achieve exacting standards.
3. Heat treatment: The process of quenching and tempering refines hardness and toughness, significantly enhancing the wire rod's durability and operational lifespan.
4. Galvanizing treatment:
Hot dip galvanizing: This involves immersing the wire rod in molten zinc, resulting in a uniform, protective coating that fortifies its defense against environmental elements.
Cold galvanizing: Employs electrolytic deposition to apply a zinc layer, which yields a refined surface finish, ideal for applications demanding precision and aesthetics.
Application scenarios

Construction engineering: Ideal for connecting steel structures and securing scaffolding, these wire rods excel with their robust weather resistance, essential for enduring construction environments.
Mechanical manufacturing: Perfect for securing transmission systems, mold positioning, and high-temperature equipment like injection molding machines, where reliability is critical.
Transportation: Essential for joining components in cars and bridges, these fasteners provide excellent resistance to both vibration and corrosion, crucial for safety and durability on the move.
Galvanized wire rods ingeniously meld the safeguarding zinc layer with exceptional strength, addressing and overcoming common issues of corrosion susceptibility and limited load capacity in metal fasteners. Their optimal use in machinery and construction underscores their status as an industry staple. Careful selection of the galvanizing process and strength grade, tailored to specific environmental and load needs, is imperative. Adhering to installation and maintenance protocols ensures their superior performance and longevity.
