Introduction | BIS for Zn-Al-Mg Coated Steel
The Indian steel industry is evolving rapidly, especially in high-performance coated steel products designed for enhanced durability and corrosion resistance. Among these, Hot-Dip Zinc-Aluminium-Magnesium (Zn-Al-Mg) alloy coated steel sheets, plates, and strips have gained significant demand in construction, infrastructure, solar mounting structures, automotive components, and industrial fabrication. These advanced coated steels offer superior corrosion protection compared to traditional galvanized steel, making them ideal for harsh environmental conditions.
BIS for Zn-Al-Mg Coated Steel standards, the Bureau of Indian Standards (BIS) introduced IS 18513:2023, which specifies the requirements for Hot-Dip Zinc-Aluminium-Magnesium alloy coated steel sheets, plates, and strips. Compliance with this standard is mandatory for manufacturers and importers who wish to market these products in India.
What is BIS for Zn-Al-Mg Coated Steel IS 18513:2023?
