Gabions are baskets manufactured from 10X12 double twisted hexagonal woven steel wire mesh, as per IS 16014 (2012), ASTM A975. 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 or PVC coated heavily zinc coated soft temper steel.

The gabion is divided into cells by diaphragms positioned at approximately 1M centre (Fig.). To reinforce the structure, all mesh panel edges are selvedge with a wire having a greater diameter.
Gabions shall be manufactured and shipped with all components mechanically connected at the production facility.
Woven Wire Mesh Type 100 X 120 mm
The mesh and wire characteristics shall be in accordance with ASTM A975/ IS 16014 (2012).Table 1, Mesh type 10X12. The nominal mesh opening D = 100 mm.
The minimum mesh properties for strength and flexibility should be in accordance with the following:
Mesh Tensile Strength shall be 51.1 kN/m minimum when tested in accordance with ASTM A975 / IS 16014 (2012).
The tolerance on the opening of mesh ‘D’ being the distance between the axis of two consecutive twists, is according to ASTM A975/ IS 16014 (2012). or EN 10223-3
