GI Wire (Galvanised Binding Wire)

GI wire is soft galvanised iron wire used for tying reinforcement bars, binding fencing, hanging ceilings and general site work. The zinc coating slows rust. Falcon Link TR supplies GI binding wire from Sharjah for building sites and workshops across the UAE.

What is GI wire used for?

On a reinforcement cage, binding wire ties bars at their crossings so they hold shape until the concrete is poured. It is also used to fix mesh, hang ceiling supports, tie bundles and secure fencing. Galvanised wire resists rust better than plain black wire, which helps in humid or coastal sites.

GI wire gauges and sizes

Figures are approximate and depend on the exact wire diameter and coating. Ask us for the coil weight and diameter available.

How to choose the right gauge

1. Decide the job: rebar tying, fencing or hanging.
2. Pick the gauge: 18 SWG is the usual choice for rebar tying.
3. Choose a coil size you can handle and store.
4. Decide how much wire per job, then add a margin for waste.

How much binding wire do I need?

The quantity depends on bar spacing, bar size and how many crossings are tied. A simple way is to ask your site engineer for the average binding wire per tonne of steel on similar work, then multiply by your steel quantity. Always order a margin.

Tips for UAE sites

• Store coils under cover and off wet ground so the coating does not wear.
• Keep a wire reel or dispenser at each tying gang to cut waste.
• Use galvanised wire for exposed fixings and seafront jobs.

Common mistakes

• Using too thin a wire, which snaps on a tight tie.
• Buying more coils than can be stored dry.
• Using GI wire where it will not be seen and plain wire is enough.
• Leaving sharp wire ends sticking out of the cage at head height.

Tying methods for rebar

• Single tie: one wrap and a twist, used for light mats.
• Cross tie: a figure-eight wrap that holds bars from sliding.
• Saddle tie: wraps around the crossing twice for stronger holding on vertical bars.

Binding wire for ceilings and hangers

Light GI wire also supports ceiling channels, cable runs and small pipework. Always check the load, because wire hangers are for light duty only. Heavier items need rods or proper hangers, such as threaded rod.

Checks when you receive a coil

1. Check the label for gauge and weight.
2. Inspect the coating for rust spots and flaking.
3. Unwind a short length and bend it to check it stays flexible without cracking.
4. Store the coil under cover and off the floor.

Handling and safety

Cut wire ends are sharp. Wear gloves when unwinding coils and bend wire tails inwards so nobody scratches an arm on the cage. Keep a snip or pliers on each tying team, and collect offcuts at the end of the shift, because loose wire is a hazard on slabs and walkways.

What to send us for a quote

• The gauge (SWG) or diameter in millimetres.
• The coil weight you prefer.
• The quantity and delivery area.
• Whether you need GI or black annealed wire.

If you are unsure which gauge your crew prefers, ask the site foreman for a sample and tell us the diameter. It is better to confirm before ordering a full coil.

What to buy with GI wire

Binding wire goes with concrete spacers, rebar safety caps and steel nails. See all fasteners and fixings.
