Surface Treatment of Gabion Box
Gabion box is twisted hexagonal woven mesh with the automatic gabion mesh machine. The gabion box are filled with stones to make the box strong and provide which is an effective permeability throughout the structure, they are self-draining. The gabion box can absorb the huge amount of energy and very strong under tension generated by the nature.
The surface of the gabion box will be treatment to make it more beautiful and anti rust. The main surface treatment are galvanized and PVC coated.
Galvanized Gabion Box
Electro galvanized gabion box
Electro galvanized is the using electrolytic to make the compact and uniform combined with good metal or alloy sedimentary process. This kind of technology will use less zinc, so this kind of gabion box will be cheap. The disadvantage will be easier to rust. The zinc amount is about 15g/m2.
Hot Dip Galvanized gabion box
Hot dip galvanize is the process of coating iron, steel or aluminum with a thin zinc layer, by passing the metal through a molten bath of zinc at a temperature of around 860 °F (460 °C). This kind of gabion box it will be much better than electro galvanized gabion box, so it will be more expensive. The zinc amount is about 60g/m2.
Heavy Dip Galvanized Gabion Box
This kind of box will be more beautiful and good quality to anti rust. The zinc amount is above 200g/m2.
PVC Coated Gabion Box
PVC coated gabion box is coating a layer of PVC protective layer before weaving by low carbon steel wire or galvanized wire. And then woven into various of gabion boxes. This PVC layer will greatly increase the useful live of the gabion box and anti-rust. The different color choose, make easier merging withe the nature and look better.
