The LINKWELD differenceManufacturingExcellenceQuality ControlPerformanceAll LINKWELD gabions aremanufactured from steel rodthat is then drawn down to theappropriate diameter for use in ourproducts. We can supply productwith wire diameters ranging from2mm to 5mm. All wire conforms tointernational standards for tensilestrength and tolerances.The wire is then coated in ourfactory with either a heavy zincor Galfan® protection that meetsinternational standards for bothconsistency and quality of suchcoatings. If required, we canadditionally coat the productwith an organic PVC for additionalprotection, in a range of colours.The wire is welded intoappropriate panel sizes to producethe LINKWELD gabion.Please ask for our detailed datasheet on the LINKWELD gabionfor all technical requirements.All LINKWELD gabions aremanufactured in our ISO 9001accredited factories so that eachtime you order you know exactlythat your product will meet ourpublished specifications.All LINKWELD gabions of coursecome with assessments of designlife performance. We want toknow that our product will giveyou many years of satisfactoryservice. Should you require fulldetails of our certification pleasecontact Global Synthetics for yourcopy.

What we offerWe offer a large range of wire diameters, mesh openings and coating types in the LINKWELD gabion range.If your project can allow the time required to manufacture against your design preference for a specificapplication, then we can almost do the impossible. We can offer a very large range of sizes and coating types.If you had curved walls in mind or a special gabion size to suit a specific application then we can help you.Even down to a particular colour for our polymer coated finishes, then we are happy to assist.If you have the time 1LINKWELD BOX SIZE - (m)L x W X HMESH OPENINGS - (mm)AVAILABLEWIRE DIAMETER - (mm)& COATING TYPE1.0 x 1.0 x 0.51.0 x 1.0 x 1.02.0 x 1.5 x 0.525 x 25 or.50 x 50 orFor mesh opening up to and including50mm x 50mmWire Diameter choice is:2.0, 2.20, 2.50, 2.70, 3.00, 4.00 and 5.0mm2.0 x 1.5 x 1.02.0 x 0.25 x 0.575 x 75 2 orAvailable with coating:Heavily Galvanised CoatingGalfan® Zn 5%Al- Coating2.0 x 0.5 x 0.52.0 x 1.0 x 0.52.0 x 1.0 x 1.03.0 x 1.0 x 0.53.0 x 1.0 x 1.04.0 x 1.0 x 0.54.0 x 1.0 x 1.0100 x 50 or100 x 100Note:For convention the firstmeasurement is the horizontalmesh opening and thesecond measurement is thevertical mesh opening.This may be reversed butmust be specified at the timeof order.For mesh opening 75mm x 75mm and up to andincluding 100mm x 100mm.Wire Diameter choice is:2.50, 2.70, 3.00, 4.00 and 5.0mm.Available with coating:Heavily Galvanised CoatingGalfan® Zn 5%Al- CoatingHeavily Galvanised Coating + Polymer CoatedGalfan® Zn 5%Al- Coating + Polymer CoatedWhen product is polymer coated the final overallcoated wire diameter is3.0, 3.2, 3.5, 4.8 and 5.8mm.1.

What we offer from our stockWe have used our experience to stock the most commonly requested sizes for our customers that gives themthe greatest flexibility in building their structure, combined with efficient and speedy delivery to the job site.Additionally, we have chosen both the mesh opening and wire diameter combination that we believe will giveyou the best, most economical strength combination whilst allowing you to maintain crisp structural lines andform that the LINKWELD gabion can offer your structure.Warehouses and Global Synthetics offices are located throughout Australia.LINKWELD BOX SIZE - (m)L x W X HMESH OPENINGS - (mm)AVAILABLEWIRE DIAMETER - (mm)& COATING TYPE1.0 x 1.0 x 0.51.0 x 1.0 x 1.02.0 x 0.50 x 0.502.0 x 1.0 x 0.5100 x 50Note:For convention the firstmeasurement is the horizontalmesh opening and the secondmeasurement is the vertical meshopening.This may be reversed but must bespecified at the time of order.Wire Diameter choice is:4.00mmAvailable with coating:Galfan® Zn 5%Al- Coating2.0 x 1.0 x 1.04

What else do I need toconsider?LINKWELD gabions are supplied flat packed and areassembled on site using LINKWELD lacing wire orLINKWELD spiral joiners. Sometimes if the project issignificant in size, you may wish to use LINKWELD“C” clips and a pneumatic lacing tool sold by GlobalSynthetics.LINKWELD gabions can be used to construct largeretaining structures. You should ensure that you seekthe necessary statutory approvals to construct suchstructures when required. This will mean that you mayneed to engage a qualified engineer who is familiar withthe design of such structures and who will assess site, soiland drainage considerations for your site. Design costsare a good investment in the life of your structure.The choice of infill rock should consider the most suitabletype that is compatible with the design requirementsof your structure. There are many infill rock types thatcan enhance the visual appearance of your structureincluding round river gravel, quarried angular stonewith a range of colours that are exhibited by such rockas basalt, limestone or sandstone. Sometimes the useof recycled materials such as concrete or brick could beappropriate. It is important that the rock infill suppliedto you is compatible with the mesh opening of theLINKWELD gabion selected. For example, if using the100mm x 50mm opening gabion then typically youwould require rock with a maximum size of around150mm and a minimum size of around 75mm, ideally therock should be graded between such sizes. Although themass will vary dependent upon the rock type selectedyou should allow for some 1.8 tonnes of rock for eachcubic metre of LINKWELD gabions to be constructed.Dependent upon the shape of your structure the numberof panels required can vary.LINKWELD gabions are modular units that consist of anumber of elements.End PanelsBase PanelsTop PanelsSide PanelsBracing WiresDiaphragm Panels*Spirals or lacing wire or “C” clips*for units that are 2m in length or greater, additional panels called diaphragmpanels are placed at 1m spacing’s along the units, giving greater internalstability.5

late my LINKWELD gabion cost?Spiral wiresIncluded in your purchase price will be spiral lacing wires. Thestandard pitch will be 25mm and are engineered to provide apositive connection between all panels. Spirals will generally besupplied in either 0.5m lengths or 1m lengths to suit your order.Some minor on site cutting to specific lengths may be required.Spiral lengths may change for speciality size units.Diaphragm unitsWhen purchasing LINKWELD gabion units where the length of panels is 2m or greater we shall includein your purchase price internal panels which increase the stiffness of your gabion structure and helps tomaintain the neat and straight lines of the unit over its service life. The diaphragm unit will ensure thatthe rock is contained in a compartment no longer than 1m in length by the height of the unit ordered.Diaphragm units are fixed in place with spirals, “C “clips or approved lacing wire.“C” clipsGlobal Synthetics are able to offer at additional purchase cost, asystem of mechanically fastening your LINKWELDgabions. Thisis achieved using a pneumatic lacing tool (compressor suppliedby customer) and specially designed closing clips. You shouldspeak to Global Synthetics in this regard, if the size of yourproject requires such equipment.Lacing wireWhenever you purchase LINKWELD product we shall supply and include in your purchase price, 2% bymass of units supplied, our approved lacing wire. This will be a 2.2 mm diameter wire and shall be coatedto the same coating quality as the units purchased. This lacing wire will be in addition to spiral wires thatwe supply and will assist with construction where it may be difficult to use some spiral wires. The methodof lacing required should be a single and double loop each consecutive opening.Other costsYou will obviously need to allow for additional costs such as rock infill for the gabion, excavation costs,drainage costs and necessary design costs. Dependent upon the structure size and complexity thesecosts may vary considerably. You should always be aware that a well designed and well constructedLINKWELD gabion structure will last for years and can enhance the aesthetics of your project.NEED HELPJust ring one of the Global sales staff at an office location closest to you and they will be pleased to assistyou in making your selection of the LINKWELD product.7
