gabion wire mesh

GABION   consist of rectangular units, fabricated from a double-twisted hexagonal mesh. Filled with stones, gabions become large, flexible and permeable elements from which a broad range of structures may be built. Gabions and mattresses are widely used for hydraulic and geo- technical control such as retaining walls, riverbank protections, weirs, channel linings etc.

GABION are divided into cells with diaphragms (usually spaced at 1 meter or 3’ intervals), whose function is to reinforce the structure. The mesh (except for the diaphragms) is reinforced on all edges with wires of a larger diameter to strengthen the gabions and facilitate the assembly and installation

.

INTERNATION STANDARD TO FOLLOW:

Manufacture

Gabion Mattress shall be manufactured from double twist hexagonal woven wire mesh in accordance with EN10233-3

 

Mesh wire Style 1 Hot-dipped galvanized wire Style 2 Galfan (Zn-5-Al) coated wire Style 3 PVC + Galvanized coated or PVC + galfan coated

The nominal mesh wire for the body of the gabions shall be 2.0mm-3.0mm in diameter

and of a nominal 2.7mm-3.4mm for the selvedge wire. The diameter of lacing wire should be 2.0-2.4mm (at the ratio 5% of the box/mattress weight) .Both the body wire and the selvedge wire, lacing wire shall be in accordance with EN 10218-2 and EN 10223-3.

 

Mesh size

The mesh openings shall be hexagonal and of nominal dimension of 60X80mm, 80mmx100mm, 100X120mm and shall conform to EN10223-3.

EN 10223-3 standard:1. Steel

Base metal of hexagonal mesh has a tensile strength which ranges between 350 N/mm2 and 500N/mm2 with an allongement of 10% minimum as per EN10016-1 and EN10016-2

2. Zinc coating

Zinc and Galfan ( Zinc –alloy with 5% of aluminum) coating varies according to wire diameter and ranges from 215gr/m2 to 275gr/m2 to confirm EN10244-2 Class A Standard.

3. Organic coating

PVC coating (1mm thickness),when required, will confirm to EN10245-1 and EN10245-2 Standards.

Tolerances:

a)      Wire diameter subject to usual tolerances as per EN10218-2 Standard.

b)      Hexagonal mesh sizes as per 10223-3 Standard

c)      Zinc coating according to EN 10244-2 Class A Standard.

d)      Length and width of gabions have a production tolerance of 3% and height of 5%.

Gabion mattress Features:1) Economic. Just fill the stone into the gabions and seal it. 2) Simple installation. No special technology needed. 3) Weather proof under natural destroy, corrosion resistant. 4) No collapse even under big scope of deforming. 5) Sludge in the stones is good for plant growing. Mixed to form a integrity with the natural environment. 6) Good permeation can prevent the damage by hydrostatic. 7) Less transport freight. It can be folded together for transport and further installation.

Gabion mattress applications: 1)Control and guide of water or flood 2)Flood bank or guiding bank 3)Preventing of rock breaking 4)Water and soil protection 5)Bridge protection 6)Strengthening structure of soil 7)Protection engineering of seaside area
