Galfan Hexagonal Gabion Basket ASTM A974 2mm Wire Dia

Galfan Material Flood bank ASTM A974 Standard 2.0mm Gabion Sacks

Gabion Sacks Introduction:

Gabion basket is a double-twisted wire mesh container of variable sizes, uniformly partitioned into internal cells, interconnected with other similar units, and filled with stone at the project site to form flexible, permeable, monolithic structures such as retaining walls, sea wall, channel linings, revetments, and weirs for erosion control projects.

Revet mattress, also called , is also a double-twisted wire mesh container with the same weaving method as gabion baskets, only having relatively smaller height and smaller mesh openings than the mesh used for gabions. Revet mattress are generally used for riverbank protection and channel linings.

A double-twisted wire mesh container uniformly partitioned into internal cells with relatively small height in relation to other dimensions, having smaller mesh openings than the mesh used for gabions;

gabion mattresses are generally used for riverbank protection and channel linings.

Gabion sacks are cylindrical baskets, which are good for water to seep through the structure, relieving the hydrostatic pressures, insure the earth's shear strength, well for whole structure's stable; meanwhile, saved the charge for traditional retaining drainage equipment, low down the whole cost.

Hexagonal opening (aperture):80x100mm

Wire diameter: 2.7mm

Selvedge wire: 3.4mm.

1.Material:
Low carbon steel wire, stainless steel wire, pvc wire, brass wire, electro-galvanized wire hot-dip galvanized wire, stainless steel coating, pvc coating etc.
2.Weave Method:
Straight twist, counter twist, double action twist,weave before galvanizing, galvanizing before weaving, and it could be divied into electro-galvanizing, hot galvanzing, plastic coating

3.applications:

Control water or flood,preventing rock breaking,water and soil protection,protecting .

4.Specifications:

material: low carbon iron wire
wire dia: 2.0mm--5.0mm
width of a roll:0.9m~1.95m
length of a roll:10m~50

5.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.
>Less transport freight. It can be folded together for transport and further installation.

Gabion Sacks Standard Specification:

We can produce the gabion baskets and revet mattress on a basis of various materials as follows.

Heavily zinc-coated steel wire conforming to ASTM A 641, Class 3 coating, soft temper;

Zn-5Al-MM-Coated steel wire conforming to ASTM A 856/856M, Class 3, soft temper;

The same type of metallic-coated steel wire as above, but with an additional PVC coating extruded onto the metallic-coated steel wire;

l Aluminum-coated steel wire conforming to ASTM A 809, soft temper;

The most popular wire diameter for gabion baskets is 2.7mm, 2.2mm for revet mattress.

Weaving:

a nonraveling mesh made by twisting continuous pairs of wires through three one-half turns(commonly called double-twisted) to form hexagonal-shaped openings which are then interconnected to adjacent wires to for hexagonal openings. The most popular mesh opening for gabion baskets is 80x100mm size, 60x80mm for revet mattress. During the process, a terminal wire will be used to edge the wire mesh perpendicular to the double twist by mechanically wrapping the mesh wires around it at least 2.5 times or by inserting it throughout the twists and folding one mesh length. We always use 3.4mm wire for gabion baskets, 2.7mm wire revet mattress.

Gabion Sacks Feature:

• 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.

Gabion Sacks Application:

• Control and guide of water or flood

• Flood bank or guiding bank

• Preventing of rock breaking

• Water and soil protection

• Bridge protection

• Strengthening structure of soil

• Protection engineering of seaside area

• stabilization of earth movement and erosion

• canal refurbishment

• landscaping and retaining walls.
