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).

Galfan Coating Standards Applied for Gabions
Wire: Galfan and PVC Galfan coated:
Coating heavy Zn-95%/Al-5% and an option for Zn-90%/Al-10%.

Gabions for Colombia Market Standard
All wires applied conform to:
New Zealand: EU or ASATM standards used in production


Export to Australia Standard

Mesh Type – Double twist hexagonal woven wire mesh in accordance to EN 10223-3
Mesh Size – The mesh openings shall be hexagonal and of nominal dimension of 80mm x 100mm and shall conform to EN10223-3
Mesh Wire – The nominal mesh wire for the body of the gabion shall be 2.7mm in diameter and of a nominal 3.4mm for the selvedge wire. The body wire, selvedge wire and lacing wire shall be in accordance with EN 10218-2 and EN10223-3


Technical Standard Applied to Galvanized Gabions for Gabion Project Implementation:
All wires shall be galvanized in accordance with ASTM A153 (AASHTO M 232).

The minimum weight of the zinc coating:

Diameter of Wire Minimum Weight of Coating gr/sq.m
2.0 mm 240
2.2 mm 240
2.4 mm 260
2.7 mm 260
3.0 mm 275
3.4 mm 275
3.9 mm 290

The adhesion of the zinc coating to the wire should be such that when the wire is wrapped six turns round a mandrel of 4 times the diameter of the wire, it does not flake or crack to such an extent that any zinc can be removed by rubbing with the bare fingers.

All wire used in the fabrication of the gabions and in the wiring operations during construction shall be mild steel wire having and average tensile strength of 45 kg/mm2.

All edges of gabions including end-panels and the diaphragms, if any, shall be mechanically selvedge in such a way as to prevent raveling of the mesh. The wire used for the selvedge shall have a diameter greater than that of the wire used for forming the mesh, namely: for gabions made of wire having a diameter of 3.0 mm the selvedge shall be of wire having a diameter equal to or greater than 3.9 mm.

Sufficient lacing and connecting wire shall be supplied for all the wiring operations to be carried out in the construction of the gabion work. The quantity of such wire is estimated to be 8-10 percent of the weight of the gabion basket supplied.

Gabions might incorporate diaphragms to form cells having a length not greater than one and a half times the width of the gabion.

A tolerance of ±2.5 percent is permitted on the diameters of all wires utilized.
