Heavy Galfan + PVC Coated Woven Wire Mesh Gabions

Changte has developed a new product: GalFan +PVC Coate woven wire mesh gabions.Popular mesh opening applied: 80x100mm. One diaphragm every one meter (or at 3ft center) is positioned to divide the gabions into cells. This structure makes the whole gabion flexible and easy to handle. This type of woven or knitted mesh gabion has selvedge wire and lacing wire for reinforcement. All mesh panel edges are selvedged with a wire having a greater diameter than the woven or knitted wire.

Special Coating Material: Galfan (zinc-5% aluminum alloy) and its benefits:
Galfan gabion gets its name from its wire material: a kind of heavy Galfan (zinc-5% aluminum alloy) soft tempered steel . Compared with traditional galvanized steel gabions with pure zinc coating, Galfan gabion features a heavy zinc – aluminum coating layer which enables an excellent corrosion resistance. The corrosion resistance of Galfan gabion doubles that of traditional pure zinc plating.

Wire Material Requirements:
The pvc coating for our Galfan Gabions can be checked below (take an example of the 80x100mm galfan gabion), from the changes of the wire diameter before and after coating:

Knitted or woven wire: 3.7mm after PVC coating (2.7mm heavy Galfan before pvc coating)
Selvedge wire: 4.2mm after PVC coating (3.2mm heavy Galfan before pvc coating)
Lacing wire: 3.2mm after PVC coating (2.2mm heavy Galfan before pvc coating)

Zinc plating or galvanization required for the Galfan Gabions:
Galvanization on Kitted & Lacing wire: Heavy GALFAN (ZnAL) min 245gr/m2
Galvanization on Selvedge wire: Heavy GALFAN (ZnAL) min 255gr/m2

The steel wire used in the manufacturing of the gabion is heavily galfan( [Zn-5 Al-MM] alloy) coated soft temper steel. A PVC coating is then applied to provide additional protection for use in polluted, contaminated or aggressive environments: in salt, fresh water, acid soil or wherever the risk of corrosion is present. The PVC coating has a nominal thickness of 0.50 mm to 1.00mm. Galfan plus PVC coating gabions, simplified as Galfan gabions, are strong and durable for long term uses.
