Gabion Mesh Specifications

Mesh Size Standards

Electronically welded wire mesh 75mm x 75mm grid.

Galfan Wire Coating

3mm or 4.5mm diameter Galfan coated wire deflection video.

Mesh Deflection Tests

Gives a good indication of the likelihood of the gabion sides bulging.

Angular Rock

Angular rock is the best gabion fill as it provides a good interlock.

4.5mm wire vs 3.0mm wire

4.5mm dia wire is 125% stronger than 3.0mm dia wire

4.5mm wire vs 4.0mm wire

4.5mm dia wire is 26.5% stronger than 4.0mm dia wire

High flood water velocities

In locations where high flood water velocities are expected, carrying woody debris and gravels in suspension, the stronger 4.5mm welded gabions are the preferred choice, to resist damage to the gabion structures during floods.
