Material Composition of Gabion Mesh

Material Composition  

Gabion mesh uses metal wires as the core raw material, meeting the needs of various scenarios through material combinations and surface treatments:

Base Metal Wires  

- Low-carbon steel wire: Low cost and good flexibility, it is the mainstream material for gabion mesh, suitable for scenarios with moderate strength requirements.  

- Stainless steel wire: Models such as 201, 302, 304, 304L, and 316 are used, offering excellent corrosion resistance without surface treatment. Commonly used in high-corrosion environments like chemical industries and marine applications.  

- Aluminum alloy wire: Lightweight with strong corrosion resistance, suitable for weight-sensitive scenarios, such as temporary fencing or high-altitude protective nets.  

- PVC-coated wire: The outer layer of the metal wire is coated with PVC or PE plastic, achieving an even coating through fluidized bed processing. This enhances corrosion resistance while providing diverse color options (e.g., dark green, grass green, blue), combining both decorative and functional purposes.

Surface Treatment Processes  

- Electro-galvanizing: Forms a zinc layer on the metal surface through electrolysis. It is low-cost but offers weak corrosion resistance, making it suitable for dry environments.  

- Hot-dip galvanizing: Involves immersing the metal wire in molten zinc to form a thicker zinc layer, significantly improving corrosion resistance. Often used for long-term outdoor exposure scenarios.  

- Plastic dipping/spraying: Applies a plastic coating on the metal wire surface, with a thickness of 0.5-1.0 mm, further extending service life while enhancing aesthetics.  

- Coating process: Utilizes the fluidized bed method, where preheated metal wires are immersed in fluidized plastic powder to form an even plastic layer. Suitable for scenarios requiring high corrosion resistance and appearance standards.
