1. Product Overview

Our PVC Coated Gabion Mesh Cage (2m × 1m × 1m) is engineered for civil engineering, geotechnical reinforcement, and hydraulic infrastructure projects requiring long-term structural integrity in harsh environments. Manufactured from double-twisted hexagonal woven wire mesh, each basket is reinforced with heavy-gauge selvedge wire and internal diaphragms to preserve dimensional stability during stone filling.

To ensure maximum service life, the steel core wire is heavily galvanized or coated with Zn-Al alloy (Galfan) prior to being extruded with an engineered, UV-stabilized Polyvinyl Chloride (PVC) protective jacket. This dual-barrier protection shields the wire core against acidic soils, marine salinity, abrasion, and industrial runoff, fully compliant with ASTM A975 standards.

2. Technical Specifications (ASTM Compliant)

All materials, dimensional tolerances, and coating performances are manufactured in strict adherence to ASTM A975 (Standard Specification for Double-Twisted Hexagonal Mesh Gabions and Revet Mattresses) and related ASTM standards.

3. Core Product Advantages

• Superior Dual-Layer Corrosion Resistance

  The fusion of a Class 3 heavy galvanized/Galfan substrate and a robust extruded PVC sheath prevents chemical leaching, oxidation, and salt-spray damage—offering design service lifespans exceeding 30–50 years in aquatic and acidic terrains.

• Flexible & Monolithic Mechanical Behavior

  The double-twisted hexagonal weave distributes tension evenly and accommodates differential ground settlement without unravelling or catastrophic structural failure.

• Natural Hydrodynamic Permeability

  Eliminates hydrostatic pressure build-up behind retaining walls. The porous structure allows groundwater drainage while supporting natural biological revegetation and ecological stabilization over time.

• Project Cost Efficiency

  Units are shipped folded flat to minimize container freight space. Fast on-site assembly using pre-formed lacing wire or pneumatic C-ring fastener tools significantly lowers installation labor costs.

4. Engineering Applications

• Riverbank Protection & Canal Linings: Resists high-velocity water scour, bed erosion, and turbulence along flood-control channels and natural shorelines.

• Gravity Retaining Walls: Stabilizes highway embankments, railway slopes, and bridge abutments against active earth pressure.

• Marine & Coastal Defenses: Ideal for breakwaters, seawalls, and groin structures exposed to high salinity and continuous wave action.

• Culvert & Weir Drop Structures: Dissipates energy and protects culvert headwalls, stormwater outfalls, and weir spillways.

• Architectural & Sound Barriers: Functions as a durable, sound-dampening perimeter wall or aesthetic landscape feature.
