A ZAM offers stronger corrosion resistance than conventional galvanized steel, especially at cut edges and in harsh environments. Its zinc-aluminum-magnesium coating forms a dense protective layer that slows rust formation and supports self-healing when the surface is damaged. At the same time, ZAM maintains good formability and surface durability, making it suitable for both structural and fabricated applications. Compared with stainless steel, it delivers similar corrosion performance in many uses at a more economical cost.

A ZAM is a hot-dip coated steel made from a zinc-aluminum-magnesium alloy and originally developed. It is essentially a steel sheet with a specialized metallic coating designed to improve corrosion resistance.
The coating combines the strengths of each element. Aluminum provides barrier protection, magnesium supports self-healing at cut edges, and zinc adds durability and surface hardness. ZAM is produced in accordance with ASTM A1046/A1046M Type 1 requirements.
Because of its performance and cost balance, ZAM is often viewed as a practical middle option between traditional galvanized steel and stainless steel.
