Structure and Material Composition
| Structure Component | Material Description |
|---|---|
| Inner layer steel wire | Usually hot-dip galvanized or high alumina (Zn Al alloy) steel wire, providing basic strength and corrosion resistance. |
| Outer coating | A layer of PVC plastic with a thickness of ≥ 0.38-0.5 mm, tightly bonded by fusion bonding. |
| Color | Commonly available in gray, green, Blue, red，and black, customizable to balance aesthetics and environmental protection. |
Material Comparison
| Type | Advantages | Applicable environment |
|---|---|---|
| Electroplated galvanized gabion | Low cost | Dry, low corrosion environment |
| Hot dip galvanized gabion | Good corrosion resistance | General water and soil environment |
| Gaolfan stone cage | Corrosion resistance superior to hot-dip galvanizing | Damp and industrial atmospheric environment |
| PVC coated gabion | Corrosion resistance+UV resistance+aesthetics+long lifespan | Seawater, sewage, and extremely cold and hot areas |

Performance advantages:
- Strong corrosion resistance: PVC coating can effectively prevent metal mesh from rusting suitable for corrosive environments such as acid rain, seawater, and sewage, with a lifespan 2-3 times longer than pure galvanizing.
- UV resistance and wear resistance: Meets ASTM G-23 standard and maintains performance after ≥ 3000 hours of aging test.
- Flexible structure: Even if the foundation settles or undergoes local stress deformation, the overall structure will not fracture or fail.
- Eco-friendly: The gaps in the net cage are conducive to plant growth and can be integrated with the natural environment, used for landscape slope protection, ecological river management, etc.
- strength and stability: The PVC coating will not affect the strength of Gabion mesh itself, and it still has the functions of support, reinforcement, and protection.
- Suitable for various application scenarios:Due to its corrosion resistance, PVC coated Gabion is often used in fields such as water conservancy engineering, road construction, slope reinforcement, and landscape design.
