Hexagonal Mesh Gabions Key Features and Applications

Specifications

• Mesh Size: The size of the hexagonal openings can vary, typically ranging from 60x80mm to 100x120mm, to accommodate different types of fill and application needs.
• Wire Diameter: Ranges from 2.0mm to 4.0mm, with or without PVC coating. The selection depends on the desired strength and durability.
• Gabion Size: Customizable to project requirements, with common dimensions for gabion boxes being 1x1x1m, 2x1x1m, 3x1x1m, etc., and for mattresses, commonly 3x2x0.3m, 4x2x0.3m, etc.
• Tolerance: Manufactured within standard tolerances for dimensions and strength, as specified in relevant industry standards.

Processing Types

• Straight Twist Hexagonal Wire Netting: This type features wire that is twisted in a straight direction to form hexagonal openings.
• Reverse Twist Hexagonal Wire Netting: In this variant, the wire is twisted in the opposite direction after every few twists, enhancing the netting’s strength and stability.
• Double-Direction Twisted Hexagonal Wire Netting: This type involves twisting the wire in two directions, creating a highly durable and robust netting.

Finishes

• Galvanized After Weaving (GAW): The netting is woven from steel wire and then galvanized, providing strong protection against corrosion.
• Galvanized Before Weaving (GBW): Here, the wire is galvanized before it’s woven into netting.
• PVC Coated Galvanized: This finish involves coating galvanized wire with PVC, offering double protection against corrosion and weathering.
• Hot-Dipped Galvanized: After the netting is woven, it’s dipped in molten zinc, creating a thick, protective galvanized coating.
• Electro Galvanized: This involves applying a thin layer of zinc to the wire through electroplating before weaving.

Characteristics

• Mesh Type: The hexagonal mesh pattern enhances both flexibility and strength, enabling the gabions to accommodate uneven settling and pressure from water or soil effectively.
• Material: Primarily made from galvanized or PVC-coated steel wire, these gabions resist environmental damage and boast a prolonged lifespan.
• Size and Configuration: Available in various dimensions, hexagonal mesh gabions can be stacked to form structures like retaining walls. They are delivered flat-packed for on-site assembly and filling.
• Filling: Typically filled with stones or rocks, chosen to prevent passage through the mesh while ensuring tight packing to minimize voids.

Advantages

• Durability and Strength: The combination of wire mesh and stone fill results in a robust structure capable of enduring severe conditions.
• Flexibility: Their ability to adjust to ground movements minimizes the risk of structural damage.
• Permeability: Stone gaps allow water flow, reducing hydrostatic pressure and mitigating water damage risks.
• Environmentally Friendly: Gabions promote the use of local fill materials and support vegetation, enhancing their integration into natural settings and providing wildlife habitats.
• Cost-Effectiveness: Generally more affordable than alternatives like concrete or steel walls, especially where fill materials are easily accessible.

Applications

• Retaining Walls: Employed for slope stabilization, erosion control.
• River and Stream Banks: Utilized to prevent erosion, stabilize banks, and support aquatic habitats.
• Coastal Defence: Effective in absorbing wave energy and safeguarding shorelines against erosion.
• Architectural and Landscaping Features: Creatively used for aesthetically appealing structures that harmonize with the environment.
