PVC Coated Gabion - Solid Structure and Colorful Surface
As we all know, the galvanized steel wire and zinc-aluminum alloy steel wire can be material of both woven gabions and welded gabions. But the PVC coated steel wire is suitable for woven gabions only. When welding, the PVC coating of steel wire will be melt and falling off on the joint of wires. It is much easier corrosion and rust, so the PVC coated wires are not suitable for the welded gabions. Welded gabions can be used the steel wires or galvanized wires for fabrication and then be treated with PVC coating. In this way, the welded gabions can be also colorful and much more suitable for the decorative applications.

GALVANIZED and PVC COATED GABIONS for Georgian Project
Gabions baskets made of double twisted steel woven 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 zinc coated soft temper steel. A PVC coating is then applied to provide added protection for use in polluted environments where soils or water are acidic: in salt or fresh water, or wherever the risk of corrosion is present. The PVC coating nominal thickness is 0.50 mm.
The gabion is divided into cells by means of diaphragms positioned at approximately 1m centers. In order to reinforce the structure, all mesh panel edges are selvedged with a wire having a greater diameter (Table 3). Dimensions and sizes of PVC coated gabions are shown in Table 1.
The material is supplied from an ISO 9001 certified factory.
Wire
Tests on wire for the manufacture of
gabions are made prior to manufacturing of gabion
mesh.
Tensile strength of the wire used for the manufacture of gabions ranges between 350-500 MPa according to EN 10223-3. Wire tolerances meeting EN10223-3.
Elongation not less than 10%, meeting with EN10223-3.
Zinc coatings meet EN10244-2 Class A.
Adhesion of the zinc coating to the wire shall meet ASTM A641-97 standard, zinc coating shall not flake or crack when rubbing it with the bare fingers, when the wire is wrapped six turns around a mandrel having four times the diameter of the wire.
P.V.C. (Polyvinyl Chloride) Coating
The technical characteristics and the resistance of the PVC to
ageing meet the relevant standards. The main values for the
PVC material are as follows:
Specific gravity: 1.30-1.35 kg/dm 3 in accordance with ASTM
D792 Table 1;
Hardness: between 50 and 60 Shore D, according to ASTM D
2240 –91;
Tensile strength: not less than 20.6 MPa, according to ASTM
D412-92;
Modulus of elasticity: not less than 18.6 MPa, in accordance
with ASTM D412-92;
Abrasion resistance: the percentage of the weight loss shall
be less than 12%, according to ASTM D1242-92.
Creeping corrosion: max. penetration of corrosion of the wire
from a square cut end shall be 1 in. (25 mm) when the
specimen has been immersed for 2,000 hours in a 5% solution
HCl (hydrochloric acid 12 Be).
Structure
The tolerance on the opening
of mesh meeting ASTM A975-97

The accelerated ageing tests are:
Salt spray test: test period 3,000 hours, test method
ASTM B117-94;
Exposure to UV rays: test period 3,000 hours at 145°
F (63°C), test method ASTM D1499-92a and ASTM G23-
93 apparatus Type E;
Brittleness temperature: no higher than 15°F (- 9°C), or lower
temperature when specified by the purchaser, when tested in
accordance with ASTM D746.
The properties after ageing tests shall be as follows:
Appearance of coated mesh: no cracking, stripping or air
bubbles, and no appreciable variation in color;
Specific Gravity: variations shall not exceed 6%;
Hardness: variations shall not exceed 10%;
Tensile strength: variations shall not exceed 25%;
Modulus of elasticity: variations shall not exceed 25%;
