Tolerances:
On the hexagonal, double-twisted wire mesh opening shall not exceed 10% on the nominal dimension.
In order to strengthen the baskets, all the edges of structure selvedged with wire of greater diameter.
ASTM 975 standard:
Style 1 galvanzied wire as per ASTM a 641, class 3 soft temper
Style 2 style 1 and overcoated with PVC
Style 3 zn-5al-mm coated wire as per ASTM a 856
En 10223-3 standard:
Galvanzied wire meets en 10244-2 and old bs 443
Tensile strength between 380n/mm2 and 550n/mm2 according to bs 1052.
Gabion mattress application:
Gabion mattresses plays an important part in preventing natural scour of water and retaining earth. It is mainly applied for river bank protection as well as foreshore and side slope protection. Meanwhile, it provides protection on water courses and coastal revetments against scour and erosion.
General specifications:
Sizes: 6*2*0.3m, 6*2*0.23m, 5*2*0.3m, 5*2*0.23m, 4*1*0.3m, 3*1*0.3m, 2*1*0.3m
Special sizes: 2.5*1*0.3m, 1.5*1*0.5m, etc
Mesh hole sizes: 60*80mm, 80*100mm
Surface treatment: heavy zinc coating or PVC coating.
The materials to make gabion mesh can be divided into four types. The first type is the hot-dipped galvanized wire, which can be classified into common hot-dipped galvanizing with the amount of zinc coating 50g/m2 and high galvanizing with the export standard for 250-270g/m2. The second type is the electro galvanized wire. The following type is the pvc coated wire. It can be pvc coated after either electro galvanizing or hot-dipped galvanizing. A variety of colors are available like grey, grass green and dark green, etc. The last type is the galfan steel wire, which can be divided into ZN-5%al wire and ZN-10%al wire.
Hot-dipped 10% zn-al gabion mesh or hot-dipped 5% zn-al gabion mesh (also called ZN-10%al gabion mesh or ZN-5%al gabion mesh) is woven with various specifications of 10% (or 5%) ZN-al alloy low carbon steel wire. Under the same conditions, the hot-dipped 10% ZN-al alloy steel wire will have a relatively longer service life compared with the 5% ZN-al alloy steel wire. In order to prolong the service life of the steel wire, a layer of pvc or pe coating will be added on the surface of the steel wire.
Heavy type galvanized hexagonal wire mesh: made with high quality low-carbon steel wire to weave, steel wire tensile strength is 38kg/m2. The wire diameter may reach 2.0mm-4.0mm. The steel wire is usually galvanized. And the galvanizing layer thickness can be made according to the customer request. Max. Galvanizing quantity can be 300g/m2.
Major applications of welded gabions:
1. Retaining wall structures
2. Prevention of current scour and erosion control
3. Bridge protection
4. Hydraulic structures, dams and culverts
5. Embankment protection
6. Rockfall prevention and soil erosion protection.
