● Low Carbon Steel:
○ SAE 1006, SAE 1008, SAE 1010
○ Q195
● Annealed Quality:
○ Soft annealed (black annealed)
○ Oil ‑ coated for rust resistance
● Variants:
○ Black Annealed Wire (construction tying)
○ Galvanized Binding Wire (corrosion‑resistant)
○ PVC‑Coated Binding Wire (special applications)

Typical – Low Carbon Wire Rod Base:
● Carbon %: 0.06 – 0.12
● Manganese %: 0.30 – 0.60
● Silicon%: ≤ 0.01
● Phosphorus %: ≤ 0.030
● Sulphur %: ≤ 0.025
● Copper %: ≤ 0.20)

Annealing reduces hardness, improves ductility, and ensures easy bending/twisting.

● Diameter (mm): 0.5 – 5.0 (common: 1.0–2.0 mm for rebar tying)
● Coil weight: 0.5 – 1000 kg (small coils, spools, or large coils)
● Tensile Strength: 350 – 550 N/mm² (soft annealed)
● Elongation: ≥ 26%
● Forms of Supply:
◌ Coil wire (big coils up to 1000 kg)
◌ Small coils (0.5–5 kg for manual tying)
