GALFAN Gabions Basket Standard Specification
GuanDa GALFAN COATED 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
Galfan 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 372-470
according to ASTM A856-97. Wire tolerances (Table 3)
are in accordance with ASTM A856-97.
2. Elongation: Elongation shall not be less than 12%, in
accordance with ASTM A370-97. Test must be carried out
on a sample at least 12 in. (30 cm) long.
3. Galfan coating: minimum quantities of Galfan shown at
Table 3 meet the requirements of ASTM A856-97.
4. Adhesion of Galfan: the adhesion of the Galfan 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 A856-97.
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 Galfan coated products
• diameter: 3.05 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)
