Heavy type hexagonal wire emsh can be made into Gabion boxes used in control and Guide of water or flood,flood bank or Guilding Bank,proventing of rock breaking,water and soil protection,bridge protection,strengthening structure of soil,protection Engineering of Seaside Area,seaport Engineering,Isolation Walls,protection of road,etc. Galvanized hexagonal wire mesh heavy type: made with high quality low-carbon steel wire to weave,steel wire tensile strength is 38kg/m2. the wire diameter may reach 2.0mm to 4.0mm. the steel wire is usually galvanized . and the galvanizing quantity can be 300g/m2. PVC coated hexagonal wire mesh heavy type: PVC coated hexagonal mesh is made of PVC coated wire that offers longer service life and better anticorrosion Property. to the Gabion, the material divides into four kinds, namely the electro-galvanized ( but not many for export ), the hot-dipped galvanized ( with the zinc-coating 50g/m2 and 250-270g/m2 separately) ; the PVC coated ( include electro-galvanized wire then PVC coated and hot-dipped galvanized wire the PVC coated ) ; the last one is the Galfan , this is a special kind material, also divides into two kinds, one is the wire with 95%Zin-5%Al , and the other with 90%Zin- 10%Al The diameter of Gabion / hexagonal wire netting to the galvanized gabion , the diameter often from 2.0mm to 4.0mm, and to the PVC gabion , the diameter from 3.0mm to 4.5mm Opening Mesh of Gabion /hexagonal wire netting 60X80mm, 80X100mm, 80X120mm, 100X120mm, 120X150mm, 130X150mm etc
