BIS Certification for Electro Galvanized Hot Rolled and Cold Reduced Carbon Steel Sheets and Strips IS 17404:2020

Electro-galvanized hot-rolled and cold-reduced carbon steel sheets and strips are used primarily in applications requiring enhanced corrosion resistance and a smooth, high-quality surface finish. The electro-galvanizing process involves applying a thin layer of zinc to the steel, which provides protection against rust and corrosion while maintaining the steel's inherent strength and formability. These coated sheets and strips are commonly used in automotive components, appliances, construction materials, and other applications where durability and a high-quality finish are essential. The combination of electro-galvanization with hot-rolling and cold-reducing processes ensures a product that is both robust and aesthetically pleasing, suitable for a variety of industrial and consumer uses.

Importance of BIS Certification

BIS certification for electro-galvanized hot-rolled and cold-reduced carbon steel sheets and strips is essential to ensure these products meet rigorous quality and performance standards set by the Bureau of Indian Standards (BIS). This certification verifies that the steel sheets and strips possess the required mechanical properties, corrosion resistance, and surface quality crucial for their intended applications. Adherence to BIS standards guarantees product reliability, consistency, and safety, preventing potential failures and ensuring long-term performance in various industrial and consumer products. BIS certification also supports regulatory compliance, fosters consumer trust, and promotes industry best practices, ensuring that the steel products meet the highest quality benchmarks necessary for effective use in demanding applications.

Indian Standard IS 17404:2020

As per the latest Quality Control Order (QCO) issued by the Ministry of Steel, Government of India on 5th February 2024, electro-galvanized hot-rolled and cold-reduced carbon steel sheets and strips must conform to the Indian Standard IS 17404:2020. This standard specifies the critical requirements for the chemical composition, mechanical properties, and surface quality of these steel products, ensuring they achieve the necessary corrosion resistance, strength, and dimensional accuracy. Compliance with IS 17404:2020 is crucial for maintaining product performance and reliability across various industrial applications, supporting the effective use of steel sheets and strips in demanding environments.
