Gabions are baskets manufactured from 8x10 double twisted hexagonal
woven steel wire mesh, as per ASTM A975-97 Gabions are filled with
stones at the project site to form flexible, permeable, monolithic
structures such as retaining walls, channel linings, and weirs for
erosion control projects. The steel wire used in the manufacture of
the Gabion is heavily Galfan (zinc-5% aluminum-mischmetal [Zn-5
Al-MM] alloy) coated soft temper steel. A PVC coating is then
applied to provide additional protection for use in polluted,
contaminated or aggressive environments: in salt, fresh water, acid
soil or wherever the risk of corrosion is present. The PVC coating
has a nominal thickness of 0.02 in. (0.50 mm). The Gabion is
divided into cells by diaphragms positioned at approximately 3 ft
(0.9m) centers. To reinforce the structure, all mesh panel edges
are selvedged with a wire having a greater diameter. Gabions shall
be manufactured and shipped with all components mechanically
connected at the production facility.

Wire
All tests on wire must be performed prior to manufacturing the
mesh. All wire should comply with ASTM A975-97, style 3 coating,
Galfan and PVC coated steel wire. Wire used for the manufacture of
Gabions and the lacing wire, shall have a maximum tensile strength
of 75 000 psi (515 MPa) as per ASTM A856-03, soft temper steel.
THE ADVANTAGES
1. FLEXIBLE
Superior to rigid type structures. The hexagonal mesh construction
permits natural adjustment to varying conditions of earth
settlement without causing fracture or collapse of the structure.
2. DURABLE
Gaps between the stones silt up naturally as time passes. Silting
supports the growth of grass and plants which serve as a bonding
agent for the stone.
3. PERMEABLE
A Gabion structure allows water to pass through, water pressure
cannot build up behind it and the structure is continuously
drained.
4. STRONG
The flexibility of the Gabion structure provides the inherent
strength to withstand and dissipate pressures exerted by water and
earth masses.
5. ECONOMICAL
Filling materials are usually found on or near the site. No
structural maintenance is needed and foundation work is usually
unnecessary.
6. NATURAL APPEARANCE
Natural stone makes the structure aesthetically pleasing especially
when subsequent vegetation growth takes place.
7. SIMPLE
Unskilled labour can be used for quick assembly.
8. MAINTENANCE
Gabion structures are easily maintained using additional mesh or
grouting.
9. FUNCTIONABLE
Once the structure is built there is no waiting period – it
functions immediately.
10. EXTENDABLE
Extensions are simple. Additional units are simply attached to the
existing ones.

Features
- Economic.
- Just fill the stone into the Gabions and seal it.
- Simple installation.
- No special technology needed.Weather proof under natural destroy,
corrosion resistant.
- No collapse even under big scope of deforming.
- Sludge in the stones is good for plant growing.
- Mixed to form a integrity with the natural environment.Good
permeation can prevent the damage by hydrostatic.
- Less transport freight. It can be folded together for transport and
further installation.
