Hot-dip Galvanized Steel Wire

Our hot-dip galvanized steel wire is designed for long-term outdoor use. Each steel wire is strictly temperature-controlled and time-managed to form a uniform and thick zinc layer. This zinc layer not only has excellent anti-corrosion performance, but also performs stably in extreme environments, which can effectively extend the service life. Compared with other ordinary galvanized products, the coating thickness of our steel wire is more uniform, and the overall durability will not be affected by local weakness. Our production process ensures the strength and toughness of the steel wire, which is suitable for high-load applications and has flexibility, which is not common in many brands of galvanized products. Especially in harsh outdoor conditions, you will find that our steel wire can maintain the protective effect for a long time, reducing the trouble of subsequent maintenance and replacement.

Other Infomation

In terms of surface treatment and coating thickness of hot-dip galvanized steel wire, we provide a variety of options to better meet customers’ usage needs and special requirements in different environments.

Surface treatment options

Glossy: The surface is smooth and bright, suitable for applications with high appearance requirements.
Matt surface: Low reflectivity, more suitable for industrial or outdoor low reflectivity requirements.
Coating treatment: Add a special coating on the galvanized layer to enhance corrosion resistance, suitable for marine or acid-base environments.
Phosphating treatment: Improve wear resistance and adhesion, suitable for industrial applications that require further painting or spraying.
Oil film protection: Provides short-term corrosion protection, suitable for protection during storage or transportation.
Passivation treatment: Prevents the formation of “white rust” and extends the service life of outdoor applications.

Coating thickness options

Standard thickness: 40-60 g/m², suitable for indoor and low humidity environments.
Medium thickness: 70-100 g/m², suitable for general outdoor environments, providing better corrosion protection.
Thick coating: 120-200 g/m², suitable for high humidity, marine environment, with the strongest anti-corrosion performance.
