Al Yamamah Steel Industries operates three galvanization plants, employing the process of coating steel products with high-purity zinc. These facilities have a combined production capacity of 160,000 tons annually.

The galvanization process is conducted in-house to protect steel products from rust and corrosion caused by rain, humidity, and other harsh environmental conditions. Moreover, galvanization is environmentally friendly, as it reduces the need to replace corroded steel products, conserving natural resources and minimizing environmental impact.
