STAY WIRE AND EARTH WIRE

Stay Wire and earth wires are made from stranded galvanised high carbon steel wires. They comprise of 3 to7 strands of such wires. All steel strands are smooth, uniform and free from imperfections such as die-marks, scratches, abrasion after drawing and also after standing. The material is then suitably packed before dispatch on wooden drum as per customer's requirement.

Size range: 6.30mm to 1.60mm diameter

Coating range: Zinc coated, light, medium and heavy

Tensile Strength range: 45Kgs/ sq.mm to 180 Kgs / sq.mm

Specification: As per BS 183 / IS 12776/ BS 443
