Hot-dip Galvanized Low Carbon Steel Wire Gabion Boxes for Lining of
Gabion Box brief:
The height of the gabion mat is much less than its length and
width, after putting the stone in the gabion mat,the gabions mats are connected together.The difference from traditional gabions is its shape, it is flat
and large,the wire diameter is usually thinner thantraditional gabions, and most is hot-dip galvanized or galfan. And
usually there are double diaphragms of gabionmat and single diaphragm of gabion mat

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.
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.
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.
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.
Low cost: Gabion systems are more economical than rigid or semi-rigid
structures for the following reasons:
• It requires little maintenance
• Its installations does not require skilled labor and stone fill
is available on site or from nearby quarries,
• It requires little or no foundation preparation, as the surface
needs to be only reasonably level and smooth.
• Gabions are porous, requiring no costly drainage provision
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.
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.
