Welded gabion

They are made from high tensile wire mesh, which can be hot dip galvanized or Galfan coated. The latter is a Zinc-Aluminum coating applied to improve the corrosion resistance of the wire. They provide reinforcement for many structures, which include: Retaining Walls Temporary Bridge Abutments Noise Barriers Beach Reinforcement River Bank Revetment Landscaped Boundaries Drainage Channels and Culverts Railway Embankments Safety Barriers Terraced Slope Reinforcement Gabions are filled with stones at the project site to form flexible, permeable,monolithic structures such as retaining walls, channel linings,and weirs for erosion control projects.The steel wire used in the manufacture of the gabion is heavily Galfan coated soft temper steel. A PVC coating is then applied to provide added protection for use in polluted environments where soils or water are acidic: in salt or fresh water, or wherever the risk of corrosion is present. The PVC coating has a nominal thickness of 0.50 mm. In order to reinforce the structure, all mesh panel edges are selvedged with a wire having a greater diameter .Dimensions and sizes of PVC coated . P.V.C. (Polyvinyl Chloride) Coating The technical characteristics and the resistance of the PVC to ageing meet the relevant standards. The main values for the PVC material are as follows:The PVC polymer has a minimum durability of 60 years when tested in accordance with UL 746B Polymeric MaterialLong Term Property Evaluation for heat aging test.Lacing Operations Lacing operations to assemble and connect gabion units are made by using lacing wire specified .
