Gabion box is a strong-structure product with hexagonal or rectangular holes, which can be  divided into woven gabion box and welded gabion box according to different fabrics. Gabion box is also called gabion baskets, which can be divided into galvanized gabion box, Galfan coated gabion box, stainless steel gabion box and PVC coated gabion box because of different materials.  HEXAGONAL MESH GABION BOX is a container that made by weaving the wire into hexagonal mesh.Hexagonal mesh gabion box is mainly used for protecting river and dam from the losing of soil and water.

Features

1、Ecology: Gabions is an environmentally sensitive solution to slope stabilization. It has already been mentioned that stone fill is done with natural stones making the gabions, naturally porous allowing interaction between the land and the water table and also persuades deposition of soil in the smaller voids between the stone fill during drainage that again promote vegetation growth.

2、Aesthetics: Gabions supporting vegetation has already been discussed; in some case the vegetation growth is so intense, making the gabion structure invisible, and pleasant to look at. Again if additional effort is given during construction, the gabion can create really pleasing structure with or without vegetation. Unlike other types of materials such a modular block walls the gabion stones do not discolor due to drainage.

Benefits

1、Flexibility: Flexibility is an important benefit of any gabion structure. The double-twist hexagonal mesh construction permits it to tolerate differential settlement without fracture. This property is especially important when a structure is on unstable soil conditions or in areas where scour from wave action or currents can undermine the toe of the structure and cause structural settlement.

2、Durability: Gabions support plant growth which provides a live coating for the wire mesh and stones, adding to their durability. Generally, the wire mesh is needed for the first few years of the structure’s life; later the void between the stones is filled with soil, silt, and plant roots which act as a bonding agent for the stones.

3、Strength: Steel wire hexagonal mesh has strength and flexibility to withstand forces generated by water and earth masses, and the pervious nature of the gabion allows it to absorb and dissipate much of that energy. This is evident on coast protection installations where gabion structures remain effective long after a massive rigid structure fails. Additionally, the double twisted hexagonal mesh won’t unravel if cut.

4、Permeability: Gabion walls are previous to water and stabilize slopes by the combined action of draining and retaining, precluding the development of hydrostatic pressure behind the gabion wall. Drainage is accomplished by gravity, as well as evaporation as the porous structure permits air circulation through it. As plant growth develops within the structure, the process of transpiration assists in removing moisture from the backfill – a much more efficient system than weep holes in standard masonry walls.

5、Low cost: Gabion systems are more economical than rigid or semi-rigid structures for the following reasons

Control and guide of water or flood

Flood bank or guiding bank

Prevention of rock breaking

Water and soil protection

Bridge protection

Strengthening structure of soil

Protection engineering of seaside area

Seaport engineering

Isolation walls

Protection of road

For easy handling and transportation, gabion box is usually shipped in bundle. First, the gabion box is folded and pressed into bundle, and then strapped with steel or nylon bandage. In this way, the gabion box package is in smallest dimension with suitable unit weight. Gabion is usually placed into 40 ft. container to maximize the freight cost.
