Welded Gabion IntroductionWelded Gabion is made of welded wire mesh. Welded gabions are faster to erect and do not need tensioning. This allows them to keep their shape, to be free from bulges and depressions and fit easily against the wall. Welded gabion can be connected with other similar containers and filled with stones to form flexible and permeable structures for retaining the riverbanks and soil. Welded Gabion SpecificationWire diameter: 2.2mm,2.7mm,3.0mm, 4.0mm.,4.5mm,5mm,6mmMesh opening:76.2mm*76.2mm,75*75mm or on request Specifications of corrosion protection are available1) Galvanised wire :-Zinc coating to BS729 (galvanised after welding 460g/sqm)Up to 5 years ago galvanising was one of the principle methods of wire protection against corrosion. Galvanising is stable in the PH range 7 to 10, outside this range PVC coated gabions should be specified.Used for general applications where water quality is good and soils are within specified PH range. i.e retaining structures, sound walls and fresh water river protection schemes.Galvanising has generally been replaced with the recent alloy coating of 95% Zinc-5%Aluminium which has superior corrosion resistance. 2) Zinc-Aluminium :-.(95% zinc-5% aluminium coatings)Developed in America some 15 years ago by the Galfan Corporation, the coating gives approximately 1.5 to 4 times the durability of a pure zinc coating. The improved durability is attributable to the presence of the aluminium which has greater resistance to corrosion. The zinc corrosion rate is higher which leaves an aluminium rich surface which provides the enhanced protection.The coating weight applied is equivalent to the coating weights specified in BS443 for zinc coating before fabrication. The coating is applied to the wire prior to fabrication and goes through a wiping process which gives it a smooth coating as opposed to the hot dip process after manufacture (BS729). Claims of heavier minimum coating weights should be viewed with caution as they are difficult to achieve with any consistency. 3) PVC coating was introduced as a protection to the core wire where pure galvanised coatings would be subject to rapid corrosion i.e saline water conditions or where the PH of the soil is outside the stable zone for zinc (stable zone for zinc is PH 7 to10). It is also used where gabions are subject to salt spray (trunk roads and motorways).The PVC coating will give a life expectancy for the structure of up to 120 years providing that the PVC coating is not subjected to mechanical or chemical damage.
