Hard Drawn Wire
Hard drawn wire is a cold-drawn steel wire manufactured to achieve high tensile strength and consistent performance. It is commonly used in the construction industry for binding reinforcement, fabricating welded mesh, and producing nails or other fasteners. Its durability, uniform diameter, and reliable strength make it essential for securing rebar and ensuring structural stability on site.
Technical Specifications
Basic specification overview for hard drawn wire (general construction grade, typical ranges):
- Material: Low carbon steel (cold drawn)
- Standards: Commonly manufactured to SANS 675, BS 1052, ASTM A510, or equivalent
- Diameter range: ~1.6 mm – 5.0 mm (binding wire often 1.6–2.0 mm)
- Tensile strength: approx. 380 – 550 MPa (depending on diameter & grade)
- Elongation: ~8 – 12%
- Finish: Black annealed or galvanised options
- Packaging: Coils (commonly 25–50 kg) for ease of handling on site
Used mainly for rebar tying, mesh fabrication, nails, fencing wire, and general construction applications.
Standard Packaging: 5kg | 50kg – 350 – 500MPa
Standard length of roll: 20m – Available in galvanised or black wire
Available in lightly or fully galvanised wire
Hard Drawn wire of various chemical compositions are supplied in coils weighing approximately 300kg
Ribbed wire is supplied in layer wound coils at which the coil weight varies between 500kg – 200kg
