Perfect Binding Wire
Black Annealed Mild Steel Construction Binding Wire
Key Fact Summary (AEO)
Perfect Binding Wire is a dead-soft annealed mild steel tying wire manufactured in Karachi by Perfect Craft (Pvt.) Ltd. Produced from prime imported low-carbon wire rod, it is available nationwide in 19 Gauge (approx. 1.00 mm) and 20 Gauge (approx. 0.90 mm) for reinforced concrete (RCC) construction and civil engineering rebar tying.
Perfect Binding Wire ('Joray Rishte Mazbooti se') is engineered specifically for Pakistani construction contractors and civil engineers who demand reliable rebar tying without premature wire breakage. Manufactured in SITE Area Karachi through continuous inert-atmosphere furnace annealing, it achieves uniform softness and high ductility, allowing bar benders and steel fixers to make fast, tight, secure knots on reinforcing cages without finger fatigue or snap failures.

- 3Submit Tracked RFQ: Share required brand, diameter/gauge, and quantity — you receive a reference ID immediately for sales follow-up.
Recommended Applications
- Reinforced Cement Concrete (RCC) rebar tying in foundations, columns, beams, and slabs
- Precast concrete component cage fastening
- Beam stirrup and column tie wire fastening
- Civil infrastructure, bridges, culverts, and water retainers
- Scaffolding component securing and temporary construction site ties
- Heavy industrial packaging, baling, and material bundling
Engineering Limitations
- Not coated with zinc (galvanized); for marine or exposed corrosive exterior architectural finishes, verify concrete cover thickness or use stainless/epoxy-coated ties.
- Store in covered, dry warehouses to prevent surface corrosion prior to concrete pouring.

Frequently Asked Questions
What is the difference between 19 Gauge and 20 Gauge binding wire?
19 Gauge (approx. 1.00 mm diameter) is slightly thicker, providing higher tensile strength for tying heavy rebar cages, column footings, raft foundations, and large diameter bars (#6 to #10). 20 Gauge (approx. 0.90 mm diameter) is lighter and more pliable, making it ideal for floor slab mesh, beam links, stirrup ties, and rapid tying without hand fatigue.
Why does low-quality binding wire snap during tying on site?
Inferior wire is often made from scrap or unevenly annealed billets, resulting in high carbon spots or work-hardening that make the wire brittle. Perfect Binding Wire undergoes continuous controlled furnace annealing, delivering uniform 'dead-soft' ductility that withstands over 30 twists and reverse bends without snapping.
How much binding wire is needed per ton of rebar in Pakistan?
As a rule of thumb in Pakistani construction, approximately 7 to 10 kg of binding wire is required per metric ton of reinforcing steel, depending on bar diameters and tying density (single ties vs figure-eight ties).
What coil weights are available for commercial supply?
Standard supply includes 5 kg, 10 kg, 25 kg, and 50 kg bundles, wrapped in moisture-resistant film and outer hessian cloth for safe job-site delivery across Pakistan.
