Woven Gabion

Woven mesh gabion boxes

Woven mesh gabion boxes are hexagonal, double-twisted wire-mesh structures.

The gabion boxes are divided into chambers by inserting diaphragms every meter. The wire used for making the boxes is made of thickly plated mild steel. The gabion units are delivered to the site flat-packed.

The double-twisted mesh connections of the woven mesh prevent the mesh from coming apart if the wire is cut or snaps, in each case the location of the fault is restricted to the neighbouring areas. The units are attached to each other using stitching wire and/or staples.

Mateial:

· Galvanized woven gabions. According to different zinc coating weight, galvanized woven gabion can be divided into electric galvanized and hot dipped galvanized. Heavier the zinc coating weight, better corrosion resistance performance.

· PVC coated woven gabions. The thicker PVC coating supplies outstanding corrosion and rust resistance performance for the gabion box. The inner wire can be carbon steel wire or galvanized wire.

· Galfan woven gabions. Galfan woven gabion refers to 5% aluminum - zinc alloy material gabion. When the gabion in the corrosive environments, the surface will form a oxidation film to resist corrosion and rust.

10% aluminum - zinc woven gabions. Higher aluminum content supplier better corrosion resistance than the Galfan woven gabions. It is suitable for high corrosive environments, though the price is higher than the galvanized woven gabions.

Technical characteristics

The mesh/wire versions generally used are summarised in the table below. In order to reinforce the structure, all edges are strengthened with a thicker wire. For the sizes and size tolerances belonging to the different versions see the table of dimensions below:
