Big Coil 1000kg Galvanized Wire Coil OD 1200mm Chain Link Fence Machine Grade

A chain link weaving line stops every time a coil runs out, and on a machine producing 2.5 mm mesh the changeover plus re-threading can cost fifteen to twenty minutes. Big coil galvanized wire wound as a single 1000 kg continuous length at 1200 mm outer diameter cuts that downtime by a factor of five compared with 100 kg coils, which is why fence factories running double shift ask for this format specifically. The requirement is not just weight: the coil has to be wound without welds, without cross-overs, and with a consistent tension so the payoff does not slap or birdsnest at speed.

We wind these coils on a tension controlled layer winder, weld free across the full 1000 kg, and check the payoff behaviour on a sample before the lot is released. Wire diameter is held to +/- 0.05 mm across the length because a drift at the last 200 kg will show up as a mesh width change that the machine cannot compensate for.

• Single 1000 kg length: weld free continuous coil means one re-threading instead of ten, cutting machine downtime sharply.
• 1200 mm outer diameter build: sized to fit standard dereeler cradles without modification and to pay off smoothly at line speed.
• Consistent tension winding: the coil does not collapse inward mid-run or birdsnest at the tail, which is the usual failure of loosely wound heavy coils.
• Gauge held across the length: +/- 0.05 mm from head to tail, so mesh width and wire pitch stay stable through the whole coil.
• Zinc options to match the market: 60 g/m2 for standard fence, 240 - 260 g/m2 for coastal and heavy duty fence lines.
• Loading engineered for weight: coil saddles and stacking plan supplied so 1000 kg coils arrive round, not ovalised.

The economics are simple. On a typical chain link line, coil changes and re-threading account for a measurable share of lost machine hours; a 1000 kg coil removes most of them and also reduces the number of cut-off ends, which are scrap. Fewer coil ends also mean fewer joints in the finished mesh roll, and joints are what buyers reject at final inspection. The format does require a dereeler rated for the weight and a loading plan that keeps the coil round in transit, so we supply a simple coil saddle drawing with the order and confirm container stacking with the freight forwarder before loading.

Coils are weight checked on a calibrated platform scale, dimensionally checked for outer and inner diameter and for winding quality, and examined for welds, kinks and cross-overs. Wire samples from the head, middle and tail are tested for diameter, tensile, elongation, coating mass and adhesion. A payoff trial on a test dereeler is run for new customers or new coil formats so any winding issue is discovered before the container leaves, not at the customer's machine.

Each coil sits in a formed pallet saddle, wrapped in VCI paper and plastic film, and secured with at least four steel straps; coils are loaded upright and braced to prevent rolling. A 20 foot container holds about 25 tons, meaning 24 - 25 coils of this size with careful stowage. Lead time is 20 days after deposit for heavy zinc options and 15 days for standard 60 g/m2. We provide a loading plan and container photo record with the shipping documents.
