Heavy Zinc 260g/m2 Hot Dipped Galvanized Wire Coil 2.0mm BWG14 Rust Resistant

A galvanized wire coil is only as good as its zinc layer, and on this heavy zinc 260 g/m2 hot dipped galvanized wire coil the layer is the specification, not a marketing line. At 260 g/m2 average coating mass a 2.0 mm BWG14 wire carries roughly three times the zinc of a common 60 - 80 g/m2 commercial coil, which is the difference between a fence that shows red rust in the second monsoon season and one that still reads bright silver after five. We draw the wire from SWRH62A high carbon rod, anneal it to a controlled 12% - 15% elongation, then run it through a continuous hot dip line where coating mass is sampled every coil rather than per batch.

Buyers comparing quotations on this item should compare three numbers: coating mass, wire diameter tolerance, and coil weight consistency. A coil that quotes 260 g/m2 but delivers 210 g/m2 on the inner wraps costs more per metre of finished fence than a coil that quotes honestly. Every coil we ship is weighed, coating tested, and marked with its own heat number so the data can be traced back to the galvanizing shift that produced it.

• Heavy zinc coating: 240 - 280 g/m2 measured by the stripping method on three positions per coil, matching ASTM A641 Class 3 and EN 10244-2 Class A requirements for severe exposure.
• Tight diameter control: 2.0 mm +/- 0.04 mm, checked with a micrometer at the head, middle and tail of every coil so chain link weaving machines do not see a gauge drift mid-run.
• Controlled softness: 12% - 15% elongation after annealing keeps the wire workable on automatic weaving and bending equipment without cracking the zinc layer at the bend.
• Adhesion you can twist: the wire passes a 4 - 6 turn torsion test and a 180 degree bend test with no flaking or peeling of the coating at the deformation zone.
• Consistent coil build: layer wound, no cross-over wraps, so the coil pays off without tangling on a rotating dereeler.
• Full traceability: heat number, coating mass and coil weight printed on the tag and repeated in the mill test certificate.

Heavy zinc pays for itself in coastal fence lines, highway right-of-way barriers, port perimeter security, and agricultural enclosures in humid climates. It is also the right input for chain link mesh that will be PVC coated afterwards: the extra zinc survives the pre-treatment acid dip better, so the finished coated mesh keeps a sound galvanic layer under the plastic. For inland, dry, short-life applications a standard 60 - 90 g/m2 coil is cheaper and perfectly adequate; we will say so instead of upselling. Where the environment is saline or industrial, the 260 g/m2 coil is the economical choice once you cost the replacement labour of a premature fence rebuild.

Each production lot is sampled for coating mass, diameter, tensile strength, elongation and coating adhesion before packing. Wire is examined for slivers, laps, seams and uncoated points under 2x magnification. The shipment file contains a mill test certificate to ASTM A641 or EN 10244-2, a coating mass report by coil, packing list with net and gross weight, and a certificate of origin. Third party inspection by SGS, BV or Intertek can be arranged at the loading port on request, with the inspection cost quoted separately.

Coils are wrapped in VCI anti-rust paper, sealed in plastic film, then covered with hessian cloth and bound with galvanized strip. Coils are loaded on wooden pallets or in bundles according to inner diameter. A 20 foot container holds about 20 - 25 tons of 2.0 mm coil depending on coil weight; 500 kg coils load faster and waste less floor space than 100 kg coils. Production lead time is 15 - 20 days after deposit, and we keep shipping documents ready for T/T or L/C at sight settlement.
