PET Gabion Mesh is a hexagonal woven structure fabricated from high-strength polyester monofilaments, offering a corrosion-free alternative to traditional steel wire solutions. This geosynthetic material is engineered specifically for extreme durability in high-salinity, acidic, or deep-sea environments where metallic oxidization inevitably occurs.

Technical Breakdown: Polyester Monofilament

The structural integrity of PET Gabion Mesh relies on Polyethylene Terephthalate (PET) monofilament. Scientifically, this is a semi-crystalline thermoplastic polymer known for its hydrolytic stability. Unlike a standard Gabion Basket made from galvanized or PVC coated steel, PET mesh contains no metallic core. Consequently, it is immune to electrochemical oxidation (rust) and hydrogen embrittlement.

The monofilament is extruded to create a material with high tensile strength and a high modulus of elasticity. Its chemical composition renders it inert to a wide spectrum of chemicals, including sulfates and alkalis found in soil and seawater. Furthermore, the material is engineered with intrinsic UV stabilizers, ensuring that the polymer chains do not degrade under prolonged solar exposure.

Spec Comparison: PET Gabion vs. PVC Coated Gabion

The following table compares the physical properties and lifecycle expectancy of PET mesh against traditional PVC coated steel mesh in marine or aggressive environments.

Core Applications

Due to its non-corrosive nature, PET Gabion Mesh is specified for projects where steel is functionally unsuitable:

• Deep Sea Aquaculture: Utilized in the construction of mariculture cages. The smooth surface of the monofilament reduces bio-fouling and algae adhesion, while the material withstands constant immersion without structural fatigue.
• High-Salinity Coastal Zones: Applied in coastal revetments and riverbank protection. In these zones, salt spray accelerates zinc stripping on metal wires; PET remains unaffected by saline concentration.
• Chemically Aggressive Terrain: Ideal for retaining walls in mining reclamation or wastewater facilities. These environments often possess soil with low pH (acidic) or high pH (alkaline) levels that rapidly degrade standard metal coatings.
