GuanDa Galvanized Gabions  are baskets made of Mesh 8 double twisted steel
woven wire mesh, as per ASTM A975-97 (Figs. 1, 2). 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. The standard specifications of
mesh-wire are shown in Table 2.
The gabion is divided into cells by means of diaphragms
positioned at approximately 1m centers (Fig.1). 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 galvanized gabions are shown in Table 1.
The material is supplied from an ISO 9001 certified factory.

Wire
All tests on wire must be performed prior to manufacturing the
mesh.
1. Tensile strength: the wire used for the manufacture of
gabions shall have a tensile strength between 350-500
MPa according to EN 10223-3 . Wire tolerances (Table 3)
are in accordance with EN10223-3.
2. Elongation: Elongation shall not be less than 10%, in
accordance with EN10016-1 and EN10016-2.
3. Zinc coating: minimum quantities of zinc shown at Table
3 meet the requirements of EN 10244-2 Class A.
4. Adhesion of zinc: the adhesion of the zinc coating to the
wire shall be such that, when the wire is wrapped six turns
around a mandrel having four times the diameter of the
wire, it does not flake or crack when rubbing it with the
bare fingers, in accordance with ASTM A641-97.

All sizes and dimensions are nominal.
Tolerances of ± 5% of the width, height, and length of the
gabions shall be permitted.

Lacing Operations
Lacing operations can be made by using the tools shown in
Fig.5. Steel rings having the following specification can be
used instead of lacing wire (Fig.4):
Heavily galvanized steel rings for zinc coated products
• diameter: 3.00 mm, ASTM A313, Type 302, Class I
• tensile strength: 1530-1745 MPa, ASTM A313-92.
Spacing of the rings must not exceed 200 mm (Fig.3)
