Steel and Iron - Mild steel and Medium Tensile steel bars and Hard–Drawn Steel Wire for Concrete Reinforcement: Part 2 Hard- Drawn Steel Wire
Summry
Hard-drawn steel wire is a cold-worked steel wire used for concrete reinforcement. It is made from carbon steel, drawn to precise diameters to achieve high tensile strength. This wire is commonly used in reinforced concrete structures, pre-stressed concrete, and fabrication of wire meshes, ensuring structural stability and durability.
Why BIS Certificate is Mandatory for Mild steel and Medium Tensile steel bars and Hard–Drawn Steel Wire for Concrete Reinforcement: Part 2 Hard- Drawn Steel Wire ?
BIS certification is mandatory to ensure the steel wire meets Indian Standards for chemical composition, tensile strength, ductility, and dimensional accuracy. It prevents substandard products that can compromise concrete structures, ensures safety, uniformity, and durability, and protects public interest by guaranteeing structural reliability in construction projects.
What is BIS Certified for Mild steel and Medium Tensile steel bars and Hard–Drawn Steel Wire for Concrete Reinforcement: Part 2 Hard- Drawn Steel Wire ?
The BIS certified specification for hard-drawn steel wire is defined under IS 1786: Hard-Drawn Steel Wire for Concrete Reinforcement. It sets standards for chemical composition, mechanical properties, tensile strength, elongation, surface finish, and dimensional tolerances to ensure the wire is safe, reliable, and suitable for reinforced concrete and prestressed concrete applications.
