Summry

Cold-reduced electrolytic tin plate is thin steel sheet coated with a uniform layer of tin through electroplating. It provides excellent corrosion resistance, solderability, and hygienic properties. Widely used in food and beverage packaging, aerosol cans, and household products, it combines steel strength with tin’s protective and non-toxic characteristics..

Why BIS Certificate is Mandatory for Cold-reduced Electrolytic Tin Plate ?

BIS certification is mandatory to ensure cold-reduced electrolytic tin plates meet Indian Standards for tin coating thickness, adhesion, corrosion resistance, and steel quality. Certification protects consumers from substandard products, ensures safe use in food packaging, maintains uniformity in manufacturing, and guarantees compliance with legal and industrial regulations in India.

What is BIS Certified for Cold-reduced Electrolytic Tin Plate?

The BIS certified specification defines the chemical composition, mechanical properties, surface finish, tin coating thickness, and corrosion resistance for cold-reduced electrolytic tin plates. It prescribes testing methods and inspection criteria to ensure consistent quality, safety for food contact, and suitability for industrial and packaging applications.
